If necessary, regrind crankshaft journal and select under-size
bearing to use with it as follows.
1) Regrind journal to the following finished diameter.
Finished diameter: 44.732 – 44.750 mm
(1.7611 – 1.7618 in.)
2) Using micrometer, measure reground journal diameter.
Measurement should be taken in two directions perpendicular
to each other in order to check for out-of-round.
3) Using journal diameter measured above and alphabets
stamped on mating surface of cylinder block, select an under-
size bearing by referring to table given below.
Check bearing clearance with newly selected undersize bear-
ing.

Rear Oil Seal
Carefully inspect oil seal (1) for wear or damage. If its lip is worn or
damaged, replace it.
For oil seal installation, press-fit rear oil seal (1) so that oil seal
housing (2) end face is flush with oil seal end face.

mark (on each cap) to crankshaft pulley side. Fit them sequen-
tially in ascending order, 1, 2, 3, 4 and 5, starting from pulley side.
After installing bearing cap stiffeners, tighten bearing cap bolts
in such order as shown in figure a little at a time and repeat it till
they are tightened to specified torque.
