I have a 89 model 580 K phase 1 that got weak pulling in forward but still strong in reverse. Did a master rebuild on the shuttle and the same results. Still strong in reverse but weak in forward. Disassembled the shuttle again and the two fiber shaft seals were broken. Ordered some today and should be here next week. But it seems like it's not enough pressure on the clutch pack. The seals could have broken during disassembly. Could it be in the forward and reverse valve? Linkage seems to be properly operating the valve. Any help would be appreciated. Thanks, Bo
