That bushing should be a press fit of atleast .003 to .005 and the I.d. of the bushing should be sized after its pressed in the connecting rod. The only thing holding it in is bearing mount!

у нас методика другая, втулка ставится с натягом в 1 сотку, после чего наружные кромки развальцовываются, внутренний диаметр достигается разверткой, либо на специальном станке. сажать втулку на фиксатор в данном узле довольно спорное решение.

Dynamic load vs. unflex bonding is not a good partnership. And how could a thin layer of oil get in between pin and bushing? The fit is slightly too tight for that. It may run-in but is relying on failsafe running properties right from the beginning.

@@martinfriedrich2617 I'm not a machinist but the material is too soft for this application and the glue will not hold under temperature. You need a harder material for this application machined slightly bigger than the hole, it must be press fitted, then dornated and finally reamed to final size

What about the new bushing replacement
@mike9500
7 күн бұрын
it should have been a press fit as the hole in the bushing and the hole in the rod MUST align or no oil will reach the pin. this is done with an interferance fit. you heat the rod end to 350*f and grease and freeze the bushing to -20 to -35*f. you pres in via a press and then you can use a end mill to cut the final oiling hole.this ensures the port does not move. but with that, you should have cleaned up the rod end hole before measuring. using some scrotch bright in a drill and soime wd40 would have been perfect for this job.

Nice work but I don't trust that Loctite for a pin piston bush. Loctite 638 works at maximum 180 degrees and it is possible that the pin piston to reach that temperature because it is so close to the piston. But maybe I am wrong and it is not reaching that temperature because of the oil splash in the engine. Have you tested before this Loctite 638 for pin piston bushes?

Well we all know why it failed -- lol. You did a good job on the machining but I doubt it will last. The bushing will spin when the engine gets hot and then the hole for oiling won't line up and it will all fail. Also bushings need an oil groove for over all oiling. The pin will gall up on that bushing with out it. A rod end should have a needle bearing not a bushing. Just my opinions.
