6 Clean the flywheel to remove grease and oil. Inspect the surface for cracks, rivet grooves, burned areas and score marks. Light scoring can be removed with emery cloth. Check for cracked and broken ring gear teeth. Lay the flywheel on a flat surface and use a straight-edge to check for warpage.

7 Clean and inspect the mating surfaces of the flywheel/driveplate and the crankshaft. If

the crankshaft seal is leaking, renew it before reinstalling the flywheel/driveplate (see Sec-tion 16).

8 Position the flywheel/driveplate against the crankshaft. Be sure to align the marks made during removal. Note that some engines have an alignment dowel or staggered bolt holes to ensure correct refitting. Before installing the bolts, apply thread-locking compound to the threads.

9 Wedge a screwdriver in the ring gear teeth to keep the flywheel/driveplate from turning and tighten the bolts to the torque listed in this Chapter's Specifications. Follow a criss-cross pattern and work up to the final torque in three or four steps.

10 The remainder of refitting is the reverse of the removal procedure.

15.3 Mark the flywheel/driveplate and the crankshaft so they can be reassembled in the same relative positions

Don't damage the mating surfaces of the sump and block or oil leaks could develop. Note: On VVT-i engines, pull down the plastic cover slotted into the left-hand end of the engine block to access the left-hand sump bolts (see illustration). 10 Unbolt the pick-up tube/oil strainer assembly and remove it for cleaning.

Discard the O-ring seals, new ones must be fitted. Plug or cover the ends of the pipes, and recover the grommet from the bulkhead. Note: On vehicles manufactured after October 1999, the pipes clamps can be released using a very small flat-bladed screwdriver to press down the silver clip (see illustration). 6...

    Removal 1 This procedure is much easier to perform if the fuel tank is empty. Some models may have a drain plug for this purpose. If for some reason the drain plug can't be* removed, postpone the job until the tank is empty or syphon the fuel into an approved container using a siphoning kit (available at most automotive parts/accessory stores). Warning: Do not start the syphoning action by mouth. 2 Remove the fuel filler cap to relieve fuel tank pressure. Relieve the fuel... [читать подробенее]
