Acknowledgements Thanks are due to Nissan Motor Company Limited of Japan for the supply of technical information and certain illustrations. Castrol Limited provided lubrication details, and the Champion Sparking Plug Company provided the illustrations showing the various spark plug conditions. The bodywork repair photographs used in this manual were provided by Lloyds Industries Limited who supply ‘Turtle Wax’, ‘Dupli-

color Holts’, and other Holts range products. Lastly special thanks are due to all of those people at Sparkford who helped in the production of this manual; particularly, Martin Penny and Les Brazier who carried out the mechanical work and took the photographs respectively, John Austin who edited the text and Stanley Randolph for planning the layout of each page.

About this manual Its aim The aim of this manual is to help you get the best value from your car. It can do so in several ways. It can help you decide what work

must be done (even should you choose to get it done by a garage),

provide information on routine maintenance

and servicing, and give a

logical course of action and diagnosis when random faults occur. However, it is hoped that you will use the manual by tackling the work yourself. On simpler jobs it may even be quicker than booking the car into a garage, and going there twice, to leave and collect it. Perhaps most important, a lot of money can be saved by avoiding the costs a garage must charge to cover its labour and overheads. The book has drawings and descriptions to show the function of the various components so that their layout can be understood. Then the tasks are described and photographed in a step-by-step sequence

so that even a novice can cope with complicated work. Such a person is the very one to buy a car needing repair yet be unable to afford garage costs.

The jobs are described assuming only normal spanners are available, and not special tools. However, a reasonable outfit of tools will be a worthwhile investment. Many special workshop tools produced by the makers merely speed the work, and in these cases guidance is given as to how to do the job wihout them, the oft quoted example being the use of a large hose clip to compress the piston rings for insertion in the cylinder. On the very few occasions the special tool is essential to prevent damage to components, then its use is described. Though it might be possible to borrow the tool such work may have to be entrusted to the official agent. To reduce labour costs a garage will often give cheaper repair by fitting a reconditioned assembly. The home mechanic can be helped by this book to diagnose the fault and make a repair using only a minor

spare part. The manufacturer's official workshop manuals are written for their

trained staff, and so assume special knowledge; therefore detail is left out. This book is written for the owner, and so goes into detail.

Using the manual The manual is divided into twelve Chapters. Each Chapter is divided into numbered Sections which are headed in bold type

between horizontal lines. Each Section consists of serially numbered paragraphs. There are two types of illustration: (1) Figures which are numbered according to Chapter and sequence of occurrence in that Chapter, (2)

Photographs which have a reference number on their caption. All photographs apply to the Chapter in which they occur so that the reference number pinpoints the pertinent Section and paragraph number. Procedures, once described in the text, are not normally repeated. If it is necessary to refer to another Chapter the reference will be given in Chapter number, Section number and where necessary, paragraph number. Cross references given without use of the word ‘Chapter’ apply to Section and/or paragraphs in the same Chapter (eg; ‘see Section 8’ also means ‘in this Chapter’).

When the left or right side of the car is mentioned it is as if one is

seated in the driver's seat looking forward. Whilst every care is taken to ensure that the informa tion in this manual is correct, no liability can be accepted by the authors or publishers for loss, damage or injury caused by any errors in, or omissions from, the information given.

Introduction to the Datsun F10 The Datsuns covered by this workshop manual are known as the F10 series. Introduced in 1976, the UK range, consisting of saloon, coupe and station wagon, is designated: 100A F-I] with a 988 cc engine and 120A F-ll with a 1171 cc engine. In North America the range, consisting of sedan, hatchback, station wagon and sports

wagon

models, is designated

F10 and has a 85.24 cu in (1397 cc)

series

engine. The F10 series is based on the Cherry 100A and 129A, having the

same well proven mechanical layout but with a new, slightly larger body. The construction is very strong with vibration and soundproofing materials used in the floor, bulkheads and body panels,

making the car unusually quiet for its size and type.

Buying spare parts and vehicle identification numbers e

e

Buying spare parts Spare parts are available from many sources, for example: Datsun garages, other garages and accessory shops, and motor factors. Our advice regarding spare parts is as follows: Officially appointed Datsun garages — This is the best source of parts which are peculiar to your car and otherwise not generally available (eg complete cylinder heads, internal gearbox components, badges, interior trim etc). It is also the only place at which you should buy parts if your car is still under warranty; non-Da tsun components may invalidate the warranty. To be sure of obtaini ng the correct parts it will always be necessary to give the storeman your car's engine and chassis number, and if possible, to take the old part along for positive

identification. Remember that many parts are available on a factory exchange scheme — any parts returned should always be clean! It obviously makes good sense to go straight to the specialists on your car for this type of part for they are best equippe d to supply you. Other garages and accessory shops — These are often very good places to buy material and components needed for the maintenance of your car (eg oil filter, spark plugs, bulbs, fan belts, oils and grease, touch-up paint, filler paste etc). They also sell general accessories, usually have convenient opening hours, charge lower prices and can

often be found not Motor factors components which pistons, valves,

‘seals/shoes and pads etc). Motor factors will often provide new or reconditioned components on a part exchan ge basis — this can save a considerable amount of money.

Vehicle identification numbers

Modifications are a continuing and unpubl ished process in vehicle manufacture quite apart from major model changes. Spare parts

manuals and lists are compiled upon &@ numerical basis, the individual vehicle numbers being essential to Correct identification of the component required. The car identification plate is located on the left-hand wheel apron in the engine compartment. The car serial number is stamped on the centre of the bulkhead in the engine compartment. The car serial number is preceded by the engine model designation, A10. Al2 or Al4. The engine cylinder block.

Routine

maintenance

ee) ke ee ag Maintenance is essential for ensuring safety and desirable for the purpose of getting the best in terms of performance and economy from the car. Over the years the need for periodic lubrication — oiling, greasing and so on — has been drastically reduced if not totally eliminated. This has unfortunately tended to lead some owners to think that because no such action is required the items either no longer exist or will last for ever. This is a serious delusion. It follows therefore that the largest initial element of maintenance is visual examination. This may lead to repairs or renewals.

in the summary

given here the ‘essential for safety’ items are

shown in bold type. These must be attended to at the regular frequencies shown in order to avoid the possibility of accidents and loss of life. Neglect results in unreliability, increased running costs, more rapid wear and more rapid depreciation of the vehicle in general. TE

Examination of components requires that they be cleaned. The same applies to the body of the car, inside and out, in order that deterioration due to rust or unknown damage may be detected.

the wheels and nuts from wear if the nuts are slackened with weight on the wheel. After refitting a wheel make a point later of rechecking the nuts again for tightness.

Safety Whenever working, even partially, under the car, put an extra strong box or piece of timber underneath onto which the car will fall rather than on you.

Cleanliness Whenever you do any work allow time for cleaning. When something is in pieces or components removed to improve access to other



areas, give an opportunity for a thorough clean. This cleanliness will

allow you to cope with a crisis on the road without getting yourself dirty. During bigger jobs when you expect a bit of dirt it is less extreme and can be tolerated at least whilst removing a component. When an item is being taken to pieces there is less risk of ruinous grit finding its way inside. The act of cleaning focuses your attention onto parts and you are more likely to spot trouble. Dirt on the ignition components is a common cause of poor starting. Large areas such as the engine compartment, inner wings or bulkhead should be brushed thoroughly with grease solvent, allowed to soak and then very carefully hosed down. Water in the wrong places, particularly the carburettor or electrical components will do more harm than dirt. Use petrol or paraffin and a small paintbrush to clean the more inaccessible places.

Waste disposal Old oil and cleaning paraffin must be destroyed. Although it makes

a good base for a bonfire the practice is dangerous. It is also illegal to dispose of oil and paraffin down domestic drains. By buying your new

engine oil in one gallon cans you can refill them with old oil and take them to the local garage who have facilities for disposal.

Long journeys Before continental in the form advance so

taking the car on long journeys, particularly such trips as holidays, make sure that the car is given a thorough check of the next service due, plus a full visual inspection well in that any faults found can be rectified in time.

/ntroduction A selection of good tools is a fundamental require ment for anyone contemplating the maintenance and repair of a motor vehicle. For the Owner who does net possess any, their purchas e will prove a consider-

able expense, offsetting some of the savings made by doing-ityourself. However, provided that the tools purchased are of good quality, they will last for many years and prove an extremely worthwhile investment. To help the average owner to decide which tools are needed to Carry Out the various tasks detailed in this manual, we have compiled three lists of tools under the following heading s: Maintenance and

minor repair, Repair and overhaul, and Special. The newcomer to practical mechanics should start off with the Maintenance and minor

repair tool kit and confine himself to the simpler jobs around the vehicle. Then, as his confidence and experie nce grows, he can undertake more difficult tasks, buying extra tools as, and when, they are needed. In this way, a Maintenance and minor repair tool kit can be built-up into a Repair and overhaul tool kit over a considerable period of time without any major cash outlays. The experienced do-ityourselfer will have a tool kit good enough for most repair and over-

haul procedures and will add tools from the Special category when he feels the expense is justified by the amount of use these tools will be put to.

It is obviously not possible to cover the subject of tools fully here. For those who wish to learn more about tools and their use there is a book entitled How to Choose and Use Car Tools available from the publishers of this manual.

Maintenance and minor repair tool kit The tools given in this list should

be considered

as

a minimum requirement if routine maintenance, servicing and minor repair Operations are to be undertaken. We recom mend the purchase of combination spanners (ring one end, Openended the other): although more expensive than open-ended ones, they do give the advantages of both types of spanner. Combination spanners - 6,7,8,9, Adjustable spanner - 9 inch

70, 11, & 12 mm

Engine sump/gearbox/rear axle drain plug key (where applicable)

Spark plug spanner (with rubber insert )

Spark plug gap adjustment too/ Set of feeler gauges Brake adjuster spanner (where appli cable) Brake bleed nipple Spanner

Screwdriver - 4 in long x x in dia (flat blade) Screwdriver - 4 in long x x in dia (cros s blade)

Combination pliers - 6 inch Hacksaw, junior Tyre pump Tyre pressure gauge

Grease gun (where applicable) Oil can Fine emery cloth (1 sheet) Wire brush (small) Funnel (medium size)

Repair and overhaul tool kit These tools are virtually essential for anyone undertaking any

major repairs to a motor vehicle, and are addition al to those given in the Maintenance and minor repair list. Included in this list is a comprehensive set of sockets. Although these are expensi ve they will be found invaluable

as they are so versatile - particularly if various drives

are included in the set. We recommend the + in square-drive type, as this can be used

with

most

proprietary

torque

wrenches.

If

you cannot afford a socket set, even bought pieceme al, then inexpensive tubular box spanner s are a useful alternative.

The tools in this list will occasionally need to be supplemented by tools from the Specia/ list. Sockets (or box spanners) to cover range in previous list

Special tools The tools in this list are those which are not used regularly, are expensive to buy, or which need to be used in accordance with their manufacturers’ instructions. Unless relatively difficult mechanical jobs are undertaken frequently, it will not be economic to buy many of these tools. Where this is the case, you could consider clubbing together with friends (or a motorist’s club) to make a joint purchase, or borrowing the tools against a deposit from a local garage or tool hire specialist. The following list contains only those tools and instruments freely available to the public, and not those special tools produced by the vehicle manufacturer specifically for its dealer network. You will find occasional references to these manufacturer's special tools in the text of this manual. Generally, an alternative method of doing the job without the vehicle manufacturer's special tool is given. However, sometimes, there is no alternative to using them. Where this is the case and the relevant tool cannot be bought or borrowed you will have

to entrust the work to a franchised garage Valve spring compressor Piston ring compressor Balljoint separator Universal hub/bearing puller Impact screwdriver

Micrometer and/or vernier gauge Carburettor flow balancing device (where applicable) Dial gauge Stroboscopic timing light

Dwell angle meter/tachometer Universal electrical multi-meter

general usage, is an electric drill with a chuck capacity of at least # in (8 mm). This, together with a good range of twist drills, is virtually essential for fitting accessories such as wing mirrors and reversing lights. Last, but not least, always keep a supply of old newspapers

clean, lint-free rags available, clean as possible.

Buying tools For practically all tools, a tool factor is the best source since he will have a very comprehensive range compared with the average garage or accessory shop. Having said that, accessory shops often offer excellent quality tools at discount prices, so it pays to shop around. Remember, you don’t have to buy the most expensive items on the shelf, but it is always advisable to steer clear of the very cheap tools. There are plenty of good tools around at reasonable prices, so ask the proprietor or manager of the shop for advice before making a purchase.

Care and maintenance of tools Having purchased a reasonable tool kit, it is necessary to keep the tools in a clean serviceable condition. After use, always wipe off any dirt, grease and metal particles using a clean, dry cloth, before putting the tools away. Never leave them lying around after they have been used. A simple tool rack on the garage or workshop wall, for items such as screwdrivers and pliers is a good idea. Store all normal spanners and sockets in a metal box. Any measuring instruments, gauges, meters, etc., must be carefully stored where they cannot be damaged or become rusty. Take a little care when tools are used. Hammer heads inevitably become marked and screwdrivers lose the keen edge on their blades from time-to-time. A little timely attention with emery cloth or a file will soon restore items like this to a good serviceable finish.

Working facilities

Not to be forgotten when discussing tools, is the workshop itself. If some anything more than routine maintenance is to be carried out,

form of suitable working area becomes essential. by It is appreciated that many an owner mechanic is forced benefit circumstances to remove an engine or similar item, without the always of a garage or workshop. Having done this, any repairs should be done under the cover of a roof. flat Wherever possible, any dismantling should be done on a clean workbench or table at a suitable working height. 4 in (100 Any workbench needs a vice: one with a jaw opening of some clean mm) is suitable for most jobs. As mentioned previously,

General description

The gearbox is fairly standard having a 4-speed mainshaft and layshaft (countershaft). A 5-speed transmission is fitted to the model F10 Hatchback. The mainshaft transm its the drive to the final drive and differential unit which shares the same housing with the gearbox. A common lubrication system is shared by the two assemblies. The final gear used in the final drive is a helical gear which is of the same design as that used in the trans mission, requiring no adjustment for gear contact pattern. The transmission gearchange is of a remote control floor shift type. It consists essentially of a hand lever, a linkage which conne cts the hand lever to the transmission, and a radius link assembly which Supports the linkage at the locati on between the control rod and the transmission.

Transmission (4-speed) — dism antling

1 Support the assembly on a stand or on a bench. The housing is made of aluminium alloy, so great care must be taken , as it js easily damaged. Prior to dismantling the unit clean all dirt and greas e from it with a good grease solvent. Remove the drain plug, drain the oil into a container and refit the drain plug.

2 Remove the bolts that secu re the clutch thrust bearing housing and the primary drive gear. Withdraw the assembly (phot o), 3 Remove the bolts that secu re the primary gear cover and remove the cover by tapping it with a soft hammer (photo). This might be a little difficult owing to the bearings in the cover. Do not prise it off with a screwdriver. It will be noted that some bolts either have a white When replacing any bolts of this type a protective Setting gasket sealer should be applied to the threads.

Then tap the pushrod right through. 2 The front section of the drive gear can now be removed by using a suitable drift and driving it out. 3. The bearings on the drive gear and idler gear can be pressed out in a vice, always ensuring that soft jaws are used and that suitably spaced blocks of wood carry the pressure. 4 Replacement is the reverse of dismantling, but if any clutch components have been renewed it is most important that the length of the pushrod is selected as covered in Chapter 5.

driveshaft

is supported

on two ball bearings mounted

back

to back, and is splined to the wheel hub. 2 Constant velocity (CV) joints are incorp orated at each end of the driveshafts. The joint at the wheel end of the shaft provides a forty-two degree swivel movement, while the double offset type of joint at the other

end of the shaft allows fora movement of twenty degrees. 3. The outer universal joints are of the Birfield constant velocity type. The driveshaft fits inside the circular outer CV joint which is also the driven shaft. Drive is transmitted from the driveshaft to the driven shaft by six steel balls which are located in curved grooves machined in line with the axis of the shaft on the inside of the driven shaft and Outside of the driveshaft. This allows the driven shaft to hinge freely on the driveshaft, but at the same time keeps them together. Enclosing the CV joint is a rubber boot.

Routine maintenance

1 At intervals of 6000 miles (10 000 km) inspect the rubber boots which protect the constant veloci ty joints. If they are torn, split or show signs of deterioration they should be renewed as soon as possible. When the boot splits the CV joint becomes contaminat ed by water, road dust and grit, which soon results in rapid failure of the bearings in the joint. 2 Wear in the joints is detected by a regular knocking when the front wheels are turned on full lock. In very severe Cases it is only necessary to turn the wheels slightly for the noise to begin.

3 Loosen the front roadwheel Securing nuts and jack-up the car on the same side. 4 Asit willbe necessary to work undern eath the car, supplement the jack with a stand or support blocks. This will minimise the danger should the jack collapse. 5 Remove the roadwheel. 6 Remove the bolts which secure the driveshaft to the final drive assembly, then use the subframe to support the detached driveshaft. 7 It will now be possible to partially free the end of the driveshaft from the centre of the hub. With a soft drift and hammer tap the end of the shaft until it is seen to move inwar ds slightly. Sometimes the shaft can be completely removed this way but great care must be taken or thesplines, bearings or oil seals will be damaged. If the resistance to the initial taps is significant it is better to obtain a special tool from your Datsun agent (ST35100000). 8 Place the special screwing in the removal tool, but take care not to damage the oil seals, 9 Inspect the driveshaft for disto rtion, corrosion or cracks.

necessary.

Constant velocity joint (inner) - dismantling

1 The double offset type of const ant velocity joint used at the final drive end of the driveshaft can be dismantled if defective parts are to be renewed. 2 Place the driveshaft in a vice equipped with soft jaws. Expa nd and remove the band which secu res the rubber boot, and remo ve the boot from the joint. 3 Use a screwdriver to prise off the retaining ring and with draw the flanged outer

ring of the joint (Fig.7.4) You will also need to remove the sealing plate from the other end of the joint. 4 Wipe grease from the ball cage and take Out the ball bearings. Rotate the cage by approxim ately half a turn, and deta ch it from the

Finally, withdraw the flanged outer ring and the rubber boot.

6 Constant velocity joint (outer) — removal and refitting eee 1 If the Birfield joint assembly shows any sign of rust or excessive play the joint should be renewed. 2 Remove the driveshaft as described in Section 3. 3 The next task is to remove the joint from the driveshaft. First remove the boot by expanding the clips and then easing it back from the joint. Remove the joint by tapping the outer edge of the CV joint with a hide or plastic headed hammer. The CV joint is held to the shaft by an internal circular section circlip and tapping the joint in the manner described forces the circlip to contract into a groove so allowing the joint to slide off. Remove the boot. 4 At this stage it is just as well to fit a new boot, since it might well Save a major operation later on. Slide the boot over the shaft and do not secure at this stage. Obtain a new CV joint and ensure that it is packed with the correct molybdenum disulphide compoun d grease. 5 Fit the CV joint onto the shaft the correct way round and with the joint pressing against the circlip. Contract the circlip right into its groove in the shaft with the aid of two screwdrivers, so the inner race of the CV joint will slide over. It may be necessary to tap the outside

ee eeeeeeeeeSSSSSSSSSSSSSFSseseFs 1 Assembly is a reversal of the dismantling procedures. Tie the band

twice round the rubber boot before tightening it with screwdriver and pliers, as shown in Fig. 7.7. A punch should be used to lock the clip to the band and then the band should be secured by bending it over. The width of the band should be used as a guide to determine how much to bend over. Exercise great care in securing the band, not to scratch the boot. When renewing grease, take great care to prevent the ingress of dirt or other foreign matter into the joint. 2 When installing the driveshafts make sure that the lips of the oil seals are lubricated with multi-purpose grease and are not damaged on installation. The driveshaft can be tapped into position with a hammer until the threads are sufficiently exposed, but the flange of the shaft should be protected with a soft pad so that the seal plate does not suffer damage 3 When fitting the driveshaft attaching bolts ensure that the nuts are to the driveshaft side. Fit the correct bolts.

4 Tighten the wheel hub nut to 87-116 Ibf ft (12-16 kgf m) and the driveshaft attaching bolts to 29-36 Ibf ft (4-5 kgf m)
