Standard oil clearance:
0.004 to 0.049 mm (0.0002 to 0.0019 in.)
Maximum oil clearance:
0.049 mm (0.0019 in.)
NOTICE:
Remove the Plastigage completely after the
measurement.
If the oil clearance is greater than the maximum,
replace the bearing. If necessary, replace the
balance shaft.
HINT:
If replacing a bearing, select a new one with the
same number.
