The torque converter pressure guage is in the green and I checked it with a manual guage - the pressure is good. I checked the pump pressure at the hydraulic filter as the manual says and it is good too. How do I know if the torque converter is failing or if it is the clutches in the power shuttle?

One being Rockford and the other Twin Disc. Twin Disc being the more expensive to rebuild. So maybe one of them have parts availability issues. I believe Twin Disc is part of Allison now.

Still works in reverse. It acts like the clutch pack is not sqeezed together hard enough. Is there any chance it could be something else. I hate to think about spitting the old girl in half.

Years back i got coned into working on a 580 B with the same problem . First off it was no picnic splitting it as i am not set up for working on Ind. When i got it apart and tore down the forward clutch pac was history . Having no contacts other then The Case dealer i am stuck with them . Come to find out that what i need to fix this thing are no longer available from case and had to get a whole unit that WOULD fit with some mods to it for use on a shuttle with out PTO . . And here was the kicker to all this , they did not know what part numbers were they needed to get to put in the PTO unit to plug the thru hole to block the oil flow where the seals went on the Thru PTo shaft as they had to be PLUGGED . .Anyway that unit cost back then over 4300 bucks plus all the rest of the pieces and parts . The guy that owned the machine had almost as much as he paid for it in repairs . I learned one thing , STICK WITH a gear drive as a clutch is a lot less money. [Reply]  [No Email]

And According to Southeast Equipment nothing was available for that ya had to get the whole unit . The soft plugs were not of a std size and i had a machine shop make them . If the parts were available i could have rebuilt it . as for the splitting of it what a pain . I'll stick to splitting wheel tractors , i knew there was a reason that i would not do industrial and trucks. [Reply]  [No Email]
