NOTE:
If replacing the cylinder block subassembly the
bearing standard clearance will be:
0.004- 0.060
mm
(0.002- 0.0024
in.)
If the oil clearance is greater than maximum, replace the
bearings. If necessary, grind or replace the crankshaft.
NOTE:
If replacing a standard size bearing with a stan-
dard oil clearance, replace with one having the same
number. If the number of the bearing cannot be deter-
mined, select a bearing from the table table blow accord-
ing to the numbers imprinted on the cylinder block and
era nkshaft.
There are five sizes of standard bearings, marked T1, T2,
