If the oil clearance is greater than maximum, re-
place the bearing.
If necessary, grind or replace the crankshaft.
HINT:
If replacing the bearing, replace it with one having the same
number as marked on the connecting rod. There are 4 sizes of
standard bearings, marked º1 º, º2º, º3º and º4º accordingly.
