seal, and repair with abrasive paper (#400) if it is
damaged.4. Install crankshaft rear oil seal [4G18-1002130].(a) Coat a little MP grease on new oil seal lip.
Note: do not let oil seal lip contact with foreign
matters.
(b) Gently knock new oil seal in with special tool and hammer
until the seal surface is parallel and level with the end sur-
face edge of mounting hole.
Note: wipe off redundant grease on crankshaft.5. Install flywheel components and clutch assembly.(a) Fix crankshaft with special tool.
(b) Clean bolts and bolt holes.
(c) Coat bolts with adhesive.

Engine mechanism - Cylinder cover gasket componentsReplacement1. Take measures to prevent gasoline leaking.
2. Remove timing chain assembly.
3. Remove camshaft.As sequences shown in the diagram, evenly loosen at
several times, and remove 19 bearing cover bolts, and then
remove 9 bearing covers of intake camshaft and exhaust
camshaft.4. Remove cylinder head assembly.(a) Remove warm air water outlet pipe from cylinder head.
(b) As shown in the diagram, evenly loosen 10 cylinder head
bolts with 10mm dual hexagonal sleeves at several times,
and then remove 10 cylinder head bolts and plain washer.
Notes:Be careful not to let washer fall into cylinder head. Incorrect disassembling sequence will cause cylin-
der head warp or chap.5. Remove cylinder head gasket components
[4G18-1003160].
6. Install cylinder head gasket components.Put new cylinder head gasket on the cylinder body.
Notes:Pay attention to installation direction.Gently put down cylinder head to avoid damaging
cylinder head gasket.7. Install cylinder head assembly.Hint: Lock up cylinder head bolts as 2 steps.
(a) Coat a thin layer of engine oil at bolt thread and the bottom
of bolt head.
