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
