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.

Why didn't made it tighter? It could rotate after some time

да не будет скорее всего, он при 112 уже становится пластичный.я так подозреваю он не делал посадку в натяг потому что нет у его расточного станка чтобы потом подогнать под палец

I have rebushed 2 Honda XR 600, they are steel on steel, no bronze bush.Bored little end and fitted bronze bushes, no interference fit and used high temperature Loctite, no problems, engineering in a can!

When I first saw Paul do this, I thought I bet he gets some tasty comments. English isn’t Paul’s native language, and I saw “bronze” in the clip and thought hmmm, no Colisbro or Trojan (brand names), and before this and pressing out the bush, and later using Locite to retain it. For all you naysayers, it can work, it just depends on the loads, lubrication & materials, as I seen in far older engines, floating “bronze” bushes in connecting rods with much heavier pistons in car engines that survive a lot longer than most motorcycles with like for like roller bearing crankshafts, and others with no bushes in connecting rods (steel on steel) that only have low flow oil pumps. I do have a Delapena honing machine, so I could ream out my connecting rods, and do an interference fit, but in all fairness it’s horses for courses, and I can see why Paul does it this way, as he maintains concentricity and running clearance this way. My only observation is in more heavily loaded used connecting rods the “eyes” or holes can become oval, and it is usually best practice to hone this round again, but if you are measuring with a good quality bore micrometer, you can spot if this is necessary, and tbh I saw Paul using one. 👍

people forgetting that it only does a half turn when in motion also cant come out because it's inside the piston ,good job it will be fine .

@mike9500 Ай 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.

@Quiet.Light.Engineering Ай бұрын

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

@canadianoddy8504 Ай бұрын

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.

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?
