tic, tic, tic.....bang!

First of all, thanks to everyone for your feedback.
I'm definately letting Big Red take a rest. Hearing that noise makes me cringe.
I have an independent PTO engagement lever. The noise is there regardless of whether the PTO is engaged or not. Turning the PTO on and off does not effect the noise. How could a heavy torque load on the PTO shaft cause a problem with the drive gears? I have no idea how the PTO is driven, but I always assumed it was independent of the drive. Was it just a coincidence?
Another thing I'm curious about is the brakes. The brakes are located in the same location and have never worked real well, could the brakes be causing some kind of noise??
I'm probably ignoring the obvious, but what you guys are saying is making me sick to my stomach.
You guys wouldn't recommend an amateur making an attempt on this? I have more time than money if you know what I mean, but if it's gonna cost me the same in parts & tools, I might as well give it to the professionals.
Thanks again for your help.

I don't think the brakes are the problem, and they were never really great on this series of tractors. Somewhere in the PTO drive train there is about a 4 to 1 gear reduction. This makes your PTO speed max out at about 540 RPM while the engine maxes out at approx 2,000 RPM. One of these gears that reduce the PTO speed could be broken.

I don't think this is an easy job for a beginner. It would probably begin with removing the lift box off of the top of the transmission. Very heavy... You might also have to split the transmission off of the rear of the tractor....

I would recommend getting a repair manual for your tractor, they can be obtained from binderbooks dot com for about $30. You can study it and decide if you want to do the job yourself. I do understand about more time than money, although I seem to be crimped on both /forums/images/graemlins/smile.gif

If you haven't already, you may want to post your question on ytmag.com. There are discussion forums there for several brands. Ususally some good answers. I am sure there are other good forums for IH.
