CLEANING AND INSPECTION CONTINUED
18. When pressing new bushings into place, be sure oil hole in bushing lines up with oil hole in connecting rod.
Bushings must then be reamed, honed, or bored to provide between 0.0001 in. (0.0025 mm) and 0.0006 in.
(0.0152 mm) clearance between bushing and wrist pin.
19. Inspect connecting rod bearings for proper fit on crankshaft journals. Check connecting rod bearings for wear.
If worn or cracked, replace rod bearings. Connecting rod caps are not interchangeable. Position caps so two
insert locking slots are adjacent to same capscrew.
20. Inspect crankshaft journals for out-of-round, and replace if necessary.
21. Inspect oil seal ring grooves for wear, and replace crankshaft if necessary.
