About this manual This Manual provides information on routine maintenance and servicing and is intended for engineers and mechanics of service outlets, garages and workshops. The Manual covers the following models: VAZ-21213 model - an off-road vehicle, three-door body of all-steel unitary construction, with 1.7 litre carburettor engine; VAZ-21214 model - with 1.7 litre Central Fuel Injection Engine; VAZ-21214-20 model - with 1.7 litre Sequential Fuel Injection Engine; VAZ-21215 model - with Turbo Diesel Engine. The chapters of the manual give full descriptions of VAZ-21213 vehicle units. For general description, service and repair procedures applicable to other models, refer to Section 9 where you can also find the information on additional and alternative equipment fitted to the vehicles. The Manual provides a detailed description of service operations on the base of OEM parts, with help- ful information on fault diagnosis, along with clear indications on removal and refitting, dismantling and reassembly, adjustment and repair of various vehicle units. We recommend to use special tools and working facilities as listed in Attachment No 2. Tighten the thread connections to torques specified in Attachment No 1. Basic adjustments and inspection checks are outlined in Attachment No 3. Refer to Attachment 4 for recommended lubricants and fuels. Due to the on-going process of vehicle improvement aimed to enhance the VAZ vehicle reliability and performance, the manufacturer can make alterations and design changes which may fail to enter this pub- lication. Such changes and alterations will be incorporated into our manuals at the earliest opportunity. The Manual describes the vehicle design as of October 1999. 3

Main bearing knocking Typical knocking or thumping noticeable at sudden throttle opening at idle which intensifies with higher crankshaft rate. Excessive endfloat of crankshaft causes sharper irregular knocking, especially noticeable during smooth increase or decrease in crankshaft speed. 1. Early ignition 2. Insufficient pressure oil 3. Loose flywheel securing bolts 4. Excessive main bearing running clearance 5. Excessive thrust washers-to-crankshaft clearance Big-end bearing knocking Big-end bearing knocking is sharper than that of main bearings. It is noticeable during engine idle at sudden throttle opening. The origin of knocking can be easily identified through switching off spark plugs one at a time. 1. Insufficient oil pressure 2. Excessive big-end bearing running clearance Piston slap Thumping noise caused by piston «runout» in cylinder. Most noticeable at low crankshaft speed and under load. 1. Excessive piston-to-cylinder bore clearance 2. Excessive gudgeon pin-to-piston groove clearance Knocking of intake or exhaust valves Excessive valve clearances cause typical regular noise; its frequency is lower than the frequency of any other engine noise, since the valves are operated by camshaft rotating at half the crankshaft speed. 1. Excessive valve clearances 2. Broken valve spring 3. Excessive valve-to-guide clearance 4. Worn camshaft lobes 5. Loose locknut of adjuster bolt Excessive noise of camshaft operation line Noise from camshaft operation line is caused by clearances between engagement elements and becomes noticeable in general engine noise at low crankshaft speed. 1. Loose chain caused by general wear 2. Broken chain tensioner shoe or damper 3. Seized chain tensioner plunger rod Insufficient oil pressure at warm engine idle 1. Foreign particles entrapped under oil pump relief valve 2. Seized oil pressure relief valve 3. Worn oil pump gears 4. Excessive main bearing running clearance 5. Excessive camshaft bearing journal-to-bearing housing clearance 6. Incorrect oil grade or inappropriate oil quality Excessive oil pressure on warm engine 1. Seized oil pressure relief valve 2. Excessively tough spring of oil pressure relief valve 10 1. Adjust ignition timing 2. Refer to subsection «Insufficient oil pressure at idle» 3. Tighten bolts to torque specified 4. Grind journals and renew bearing shells 5. Fit new thrust washers, check clearance 1. Renew valve 2. Renew spring 1. Refer to «Insufficient oil pressure at idle» 2. Fit new bearing shells and regrind journals 1. Adjust clearances 2. Renew spring 3. Replace worn parts 4. Renew camshaft and levers 5. Adjust clearance between lever and cam, tighten locknut 1. Renew pistons, rebore and hone cylinders 2. Fit new rings or new pistons with rings 1. Tighten chain 2. Renew tensioner shoe or damper 3. Eliminate seizure 1. Clean valve from foreign particles and flash, clean oil pump 2. Renew valve 3. Repair oil pump 4. Turn journals and renew bearing shells 5. Renew camshaft or bearing housing 6. Change oil as recommended in Attachment 4
