Figure 3C-24. Installing New Connecting Rod Bushing

Oversize piston pins are available .002, .004, .006, .008 and .010 in. oversize.

Ream new bushing to size, or preferably, ream nearly to size and finish to exact size with a hone (Reamer, Part No. 94800-26). A properly fitted pin should have .001 in. clearance; with this clearance, pin will have just noticeable shake in bushing. Fitting tighter is likely to result in a seized pin or bushing loosened in rod.

After installing new connecting rod upper end bushings in connection with only a top overhaul, connecting rod alignment must be checked the same as when an engine is completely overhauled.
