union, leaving standard position protruding from the cylin-
der head.

(i) Measure the Plastigage at its widest point.
Standard oil clearance:

Maximum oil clearance.
STD 0.07 mm (0.0027 in.)
U/S 0.25 0.08 mm (0.0031 in.)
If the oil clearance is greater than maximum, replace the bear-
ings. If necessary, grind or replace the crankshaft.
HINT:
If using a standard bearing, replace with one having the same
number. If the number of the bearing cannot be determined, se-
lect the correct bearing by adding together the numbers im-
printed on the connecting rod cap and crankshaft, then select-
ing the bearing with the same number as the total. There are 5
sizes of standard bearings, marked º1º, º2º, º3º, º4º and º5º ac-
cordingly.
