DC Live PTO Noise

[Jon Vidulich]

The live pto on the side of the tractor is making a lot of racket when the clutch is engaged, maybe a bearing? There is a minor amount of up and down play, which would seem to indicate this, but what really bothers me is the amount of play when I turn the pto. I would say it has almost a quarter turn in each direction. Is there a way to tighten the chain? Any thoughts?

The chain drives the hydraulic pump, has nothing to do with your 1/4 turn play. How much play when you push and pull on the shaft? There is not much in there to make noise. I think you will just have to tear into it. Problem could be as far ahead as the pressure plate on the flywheel. Keep us posted. DK

take it apart and put a new chain in there , , and if the bearings is loose ,, well you know what needs to be done btdt ,,simple fix compared to MODERN BULL/S--TRACTORS

If your noise is up front and when you have the belt pully shaft running, it could be the double row ball bearing at the rear of the clutch shaft (transmission input shaft) ahead of the pinion has failed. That is what I got from your description of a "front power take off" on the side. That does cause a very loud whine when it fails and also could give a increase in backlash on the pto drive gear up at the pinion where the pto drives from in front of the transmission bevel gear. mEl

I would describe the noise as a growling, whirling sound coming from inside behind the side pto. It gets bad the second I start to engage the clutch lever.

I drained the gear oil last night and found that it only had 5gal in there, so maybe thats the problem or at least why there's a problem with a bearing now. I think there should have 10gal correct?

Also when I pulled the drain plug there seemed to be a lot of dirt or sand in the bottom. What's the best way to flush all that stuff out?

Update on the DC: The noise goes away for the most part when I"m going down a hill, not sure what that means. Any idea"s?

On a side note, this forum really needs a promote feature, so that when your post gets a reply it automatically goes to the top of the forum list. Without this post disappear quick and folks need to keep posting on the same topic. My 2 cents anyway.

John, if you would switch to modern view it would do just that. I switched a while ago and you can edit your posts from there, a dedfinate advantage if you have additional thoughts to offer. mEl
