jonathan mirgon said: (quoted from post at 13:22:25 02/06/09) Do the c-123 replacement rod piston pin inserts have to be machined to obtain proper clearance or are they a press them in and go design ? Just wondering if the rod insert replacements will require machine shop work ?
Piston pin bushings are a press fit in the rod. After they are pressed in they should be burnished which involves pressing a special tool through the bushing to expand it to insure a tight fit in the rod. After burnishing they will be about .010 smaller than the pin. They need to be honed to .0002 clearance. When properly fit, with the pin and bushing lubed with 30 weight oil, when held with the pin vertical, it should slowly slide through the bushing with just its own weight.
The crankshaft bearings do not require any machining but the big end of the rod must not be distorted. they do need to be matched for proper size with the crankshaft.
