2290 torque limiter still slipping

I posted a while back on this subject and am still having trouble. I split a 2290 a while back because it only had 1st and rev. I split the tractor and find that c3 pistons were melted into the piston and would not apply pressure to lock up. I repaired the rps and inspected the torque limiter disc and found it had slipped to the point where all the facing was worn off. Replaced the disc tractor slipped in all three rps gears. Split the tractor for the 2nd time and had the flywheel reground. Ended up taking .018" off to clean it up. Put it back together and it still slips. Split it for the 3rd time and replaced the belleville spring that pinches everything against the flywheel and installed another brand new torque limiter disc just for fun and the tractor still slips in every rps gear. I checked the seperator plate thickness and the spacer thickness and they should be a match together. There are two thickness of seperator plates a thick one and a thin one and I have the thin one with the shorter spacers. Not sure if I should split it again for the 4th time or let it burn in and see what happens because I'm running out of things to replace. One last thing I did dyno it just to verify hp and it has 136 pto. Thanks
 
MM, I am trying to figure out why that torque limiter did not slip for you at first when it was worn out. I have replace many of these and never had a replacement one slip and I usually only replace the disc even though the book says replace the other parts also. After they seem to have slipped a lot does the disc and pressure plate shows signs of wear and heating. I am wondering if the power shift is slipping but it is unusual for that to slip in all speeds also. If I remember correctly the late 2294's had a double disc set-up you could up grade to, but truthfully at stock HP you should not have to. Rod.
 
a dumb question but you are not installing it backwards are you? some of them hit the flywheel and will not seat? just thinking out loud
 
You could shorten the spacers a bit, .010-.020". That will put more squeeze on the bellview washer. We often did that with the 70 series that we turboed.

I've thought about that. I called the place where I got the tl disc (aftermarket) and they claim that the Belleville spring cannot be pressed flat or they won't hold. I felt the spring by hand and it has a slight angle to it and I measured between the top of the spring and the seperator plate and there was 3/32" gap so it's not pressed flat. I may have to try what you said and shorten the spacers I think I have some 70 series ones somewhere I cold try to modify. Thanks
 
I hope you don't mind me asking this but When you say aftermarket are you meaning for a Ag application for the Case tractor or just a Belleville spring that is similar in size and shape?

My first though is the Belleville spring you used isn't up the snuff meaning not too case standards for the application.

A small difference in thickness or height or material quality can affect the ability for the Belleville spring to work.

Just my first thoughts. Plus remember there is always the chance of the part being miss-labeled since its after market
 
Bellville springs are inexpensive in stock sizes. Write down what you have to start with, then look at some bellville spring catalogs. They explain how to select the springs and how to stack them to get the force and travel you want.

Lee Spring is a good catalog.
