YM 2210B Bumping sound in rear end

Postby Pm wells » Sun Jul 07, 2019 4:47 pm

I have a YM 2210B 2wd that makes a bumping sound in the rear end when I let the clutch out, it is like it has slack that it takes up under a load. In lower gears it is not that noticeable except when the clutch is first engaged. Any help would be appreciated, Thanks

Not enough information to pinpoint the problem. Not saying you are able to give more. Any chance of a video?

I may be able to make a video, when my son has time to help me with it.
When tractor is standing still and you let clutch out, it is like it has slack before it moves for just an instant, it has to take up before wheels turn, making a bumping sound or thump. In higher gears it is louder.

Could it be power shift clutch plates making a bumping sound as they engage, just guessing.

I was told today by an experienced Yanmar mechanic, that this sounds like an axle bearing going bad. Well that means a little work taking the pto out and pulling the axle for inspection and repair.

Hope that is a good diagnosis. I don't see the connection between the slack when letting out on the clutch and a wheel bearing.

It's one of those things that you know something is wrong, do you start to tear into it hoping to find the problem, or let it go until you know for sure what the problem was after it breaks, which may take a long time.
