(4) Mounting the crankshaft
1) The crankshaft and the crankshaft gear are
shrink-fitted. If the crankshaft and the
crankshaft gear have been disassembled,
they have to be shrink-fitted [heat the crank
shaft gear to 180- 200 deg. C in the hot oil
and press fit to the crankshaft].
2) Coat the crank journal part of the cylinder
block and the upper main bearing metal with
engine oil and fit the upper main bearing
metal onto the cylinder block.
Note:
1) Be sure not to confuse the upper and lower
main bearing metals. The upper metal has
an oil groove.
2) When mounting the thrust metal, fit it so that
the surface with the oil groove slit faces
outwards, crankshaft side.
3) Coat the crank pins and the crank journals of
the crankshaft with engine oil and place it on
the upper main bearing metals.
Note:
1) Position so that the crankshaft gear is on
the gear case side.
2) Be careful not to let the thrust metal drop.
(5) Mounting the main bearing cap
Coat the lower main bearing metal with engine
oil, and mount it to the main bearing cap.
Note:
1) The lower main bearing metal does not
have an oil hole.
2) The base bearing thrust metal is fitted
with the oil groove facing outwards.
1) Coat the flange and the thread of the main
bearing bolts with engine oil, put them on
the crankshaft journal, and tighten the main
bearing bolts to the specified torque.
