Apply engine oil to the entire face of the tappets
and slide them into the tappet holes on the cylinder
block.
3.
Wet the cam bush inside diameter and camshaft
with oil, and carefully assemble them while turning
the camshaft.
Be careful not to generate a damage to camshaft
and bush.
4.
Check to see that the camshaft rotates smoothly.

1.
Install the main bearing (refer to assemble
sequence : right figure) machined with two holes in
the cylinder block so that the key is aligned with the
key groove, then apply oil to the bearing surface.
2.
Heat the crankshaft gear for at least 10 minutes to
120°C, then apply sealant (Loctite # 641) to the
inside wall of the heated crankshaft gear evenly
before inserting it to the end of crankshaft.
