Oil Clearance between Crankshaft Journal and Crankshaft
Bearing 1
1.
Measure the O.D. of the crankshaft front journal with
an
outside
micrometer.
2.
Measure the I.D. of the crankshaft bearing 1 with
an
inside
micrometer, and calculate the oil clearance.
3.
If
the oil clearance exceeds the allowable limit, replace the
crankshaft bearing 1.
4.
If
the same size bearing
is
useless because of the crankshaft
journal wear, replace it with an undersize one referring to the
table and figure.

Replacing Crankshaft Bearing 1
(When removing)
1.
Press out the used crankshaft bearing 1 using a crankshaft
bearing 1 replacing tool.
(When installing)
1.
Clean a new crankshaft bearing 1 and crankshaft journal bore,
and apply engine oil
to
them.
2.
Using a crankshaft bearing 1 replacing tool, press
in
a new
bearing 1 (2) so that its seam (1) directs toward the exhaust
manifold side. (See figure)
