1965 190XT gas , noise in the torque tube

I have a lot of noise coming from the torque tube when the PTO is engaged or the power director is in neutral or low . High side power director is perfectly quiet unless PTO is engaged . Where should I start looking , and for what ? I'm new to this sort of thing , so my apologies if I've posted in the wrong place .

Thank you Sir ! I will do just that . Are the bearings and/or gears still available for this tractor ?

I'm always up for a challenge . I've split some Oliver's bigger than this 190 , just never run across one with a problem like this . Thought it kind of odd that it was quiet on the high side unless the PTO is engaged , but noisy on the low and neutral all the time .

I recently had to have the PTO gear changed on my latest 180 gas tractor. Whenever you engaged the PTO, it would have a real growl and a lot of noise in the torque tube. Took it apart and had to replace the PTO gear with a real good used one, all new gaskets and, while I was in there, I installed a clutch unit and turned the flywheel as well. The problem was the gear had three teeth off it. The guy I bought the tractor from told me he always had a problem with getting it engaged, that all it wanted to do was growl and make noise! I think he was just trying to force it in and knocked off the teeth in the process. There's a lot of labor involved, that's for sure. I also put new oil back in it, while I was doing the job...not the old. Cost for everything was about 2800.00, but I did have a new fuel pump installed and carb. work done, along with cleaning the fuel tank.   Rick

My PTO engages smoothly , tractor doesn't jump out of any gears , power director works perfectly . Shows just under 3000 hours on the clock . The brake and clutch pedals show very little wear . The drawbar isn't elongated like it has pulled any heavy loads on a regular basis . The tractor was a one owner from central Illinois before I purchased it . She now resides around Springfield , MO . The hardest work she'll be doing now is pulling a brush hog .

My 180 is a gas tractor, but...like I said, I think the guy I bought it from was just pushing the PTO lever and cramming into gear and not using the clutch to do it. That's what broke the teeth off the gear! He said he didn't have it long and didn't really know much about it and I believe him now! LOL! It can't be good at all, with what's going on inside the 190 gasser though! If it isn't something serious now, it soon will be... Rick

If you must, you must. It sure isn't going to help it any. Time will tell.

I think I'll just go ahead and pull her in the shop and park it then . It's too good of a tractor to risk tearing up . Everything else on it works fine.....just the noise from the PTO and low side power director . I already have the paint and a full set of decals for it , but want to make sure everything is right before I lay the orange on her .

Does anyone know if a 190XT Series 1 and a Series 3 torque tube will interchange ?

It will come out from the rear if you are creative enough. A single split isn't bad. A double split on a tractor that big can be dangerous, if you don't have proper tooling.
