Important Operations

1. Cylinder 

Body

Use compressed air to thoroughly clean the inside and
outside surfaces of the cylinder body, the oil holes, and the
water jackets.

2. Tappet

1)  Apply a coat of engine oil to the tappet 

c

 and the

cylinder body tappet insert holes 

d

.

2)  Locate the position mark applied at disassembly (if the

tappet is to be reused).

Note:

The tappet must be installed before the camshaft
installation.

3.  Crankshaft Upper Bearing

The crankshaft upper bearings have an oil hole and an oil
groove. The lower bearings do not.

1)  Carefully wipe any foreign material from the upper

bearing.

Note:

Do not apply engine oil to the bearing back faces and
the cylinder body bearing fitting surfaces.

2) Locate the position mark applied at disassembly if the

removed upper bearings are to be reused.

4. Crankshaft

Apply an ample coat of engine oil to the crankshaft
journals and the crankshaft bearing surfaces before
installing the crankshaft.
