My 1963 1010 had no power in forward, especially once it warned up. After changing the filter and testing pressures and finding low pressure with the reverser in forward, I pulled it and rebuilt it. I replaced piston rings and seals and forward clutch piston. Both of the clutch packs had one separator plate where the tabs were deliberately bent slightly and I straighten the reverse one. After reinstalling everything, I find that the reverse clutch pack is always partially engaged. With the reverser in either forward or reverse it will creep backward with the clutch depressed. With the clutch released it works fine in reverse, but strains in forward. I took the engine back out expecting the reverser to be jammed, but with the transmission in gear, I can spin the transmission shaft freely by hand.
I don’t think it is a mechanical bind. I think reverser is always getting some pressure to reverse pack. The rotary valve was not touched or removed. I checked the gasket between the accumulator housing and forward-reverse valve housing, thinking there might be a leak through the gasket.
Before I pull the reverser out I’m looking for guidance. If the reverse clutch pack is not getting the 25 lbs pressure would this cause the partial engagement? Any other idea about how this could happen? Should I have left the reverse separator plate tabs bent? I could see tool marks and there was nothing in the manual about bending them.
