Hello all. I've done a bit of reading and I think the pump is bad. I'd like to hear your thoughts please. So, I bought a 632, 1978 I'm told. Ford engine. Left side drive is weak, almost no forward power, some reverse power but not like the right side. Right side works good. I tried changing the bronze filter but Bobcat sent the wrong one so I cleaned it with brake cleaner, blew it out with air and let it sit to completely dry. It was easy to blow air from my lungs through it so I don't think that's an issue. lol At the same time, I swapped the high pressure valves and none of that made a difference. So then, I swapped the motor lines at the pump and now everything is reversed and the right side is weak. So that would say the pump is bad and not putting out the pressure for the left side in normal configuration, right? Also, how hard is it to rebuild the pump and what goes wrong inside them to cause this? Any thoughts or resources would be nice. Thanks.
