Measuring crankshaft end play
1. Install the thrust bearings in position, then secure
the bearing cap. Under this condition, measure
the end play. If the end play exceeds the stan-
dard clearance, replace the thrust bearings.
2. If the end play still exceeds the repair limit even
after the new thrust bearings have been installed,
replace the bearings with the next oversize bear-
ings. There are three sizes for the thrust bear-
ings:
+ 0.25 mm [+0.0098 in]
+ 0.50 mm [+0.0197 in]
+ 0.75 mm [+0.0295 in]
NOTE! Generally the rear journal is likely to wear
more rapidly than the front journal. This means that
replacement of the rear thrust bearings will generally
be sufficient.
