L3600 Kubota GST noise

[Larry Hilbrandt]

There is 611 hours on the tractor and the clutch was changed @ 591 hours. Now there is a rumbling noise when the gear lever is in 4 th @ 8 th gear. The tractor does not have to be moving. It gets worse when you are driving it. The dealer that installed the clutch does not know if they can find the problem. It started when they installed the clutch. The noise stops when the foot clutch peddle is pushed down. I need help! Larry

Throw out bearing?

Does it only happen in 4th and 8th and no other gears?
Or does it still happen in other gears just only less noticeable?
It's rumbling with the clutch in and out, that would tell me it's in the clutch or the clutch disk, also a very remote possible that the pilot bearing is out, that will cause vibrations.
When they did the clutch replacement did they change the pilot bearing, throw-out bearing, pressure plate and clutch disk?

I'm sorry for the reason, but welcome to OTT!
Will they honor their work if it is connected to replacing the clutch?

The throw bearing was replaced, also the pilot bearing, pressure plate, clutch and all the clutch pack parts. Everything is new. There is a slight noise in 3 rd and 7 th also. With the foot clutch depressed there is not any noise. The dealer said if it is there fault they take care of the problem at there expense. I have lost faith in the dealer because I took it back three times and they did nothing. I paid $3200 to fix the clutch and if they say it is not there fault I will be giving them a blank check.

Since it's doing it in several gears, I'm 99% convinced that it's a clutch problem.
It's sad when a repairing party won't just admit to there being a problem with there work.

I would have to agree with the rest. That really sounds like a throw out bearing if it is quite when you depress the clutch.
