Hello all, my cousin bought a case 530 tractor a while back, said there was something wrong with the brakes when you would back up. He didn't get a chance to tear into it until a week or so ago. He said he thought the brakes were hanging up on it when you would back up, because he said it would bang when you backed up if you hit the brakes. I went down to look at it, he had it in his shop on stands, tearing the brakes apart. I was rolling the tire around while talking to him and could hear something like gears hitting when it was in neutral, loud. I told him we should pull trans cover to find out what the noise was and this is what we found. The retaining bolt on the reverse idler shaft had come out and had been thrown up onto the oil trough that directs oil in the rear end. But the noise I heard was the shifting fork was holding the reverse idler gear against the gear it shifts into, and had ground the reverse idler gear off a good bit. The shifting fork had been cut off and rewelded on (apparently not in the right spot) and the fork was wore badly from holding the gear against the other gear. Any idea why this would have been done? Had a hard time finding the gear but he finally found one, but hasn't been able to find the fork yet. Everyone asks for the s/n when looking for parts, but the panel below the dash where I believe it should be is missing. Tractor drove and worked fine except for the bang in reverse, he wasn't too worried about it though. I should also mention that the trans and rear end were full of hy-tran, which I'm pretty sure that gear drive should have gear oil in it? Never worked on a case except for my grandfather's old 320 backhoe (now gone), trying to keep its cobbled up self running for him while he was alive. Just wondered why someone would have modified that fork, or if they had a problem on those tractors. Thanks
