Cleaned off any burrs to avoid damaging o ring. Reinstalled using pvc pipe as videos suggested. Gland was a bit tough to push through but went it. Pushed piston back and forth, went smoothly, held air pressure when filler hole covered with finger. Put it all together...still no variable drive...but, no leaks whatsoever... Took the supply line off, it's providing plenty of oil, with tons of air bubbles. Clearly I'm sucking air in somewhere. Main hydraulic cylinders chatter and are slow, but work. Tested the psi at the supply line...65 psi whether at idle or full throttle. Clearly it's set for that... Is it possible 65 psi isn't enough to compress the sheave? Is there a way to adjust the psi at the sheave? What's too much? The air leak is killing me, can't find it. When it gets warmer will power wash this thing so I can find/fix all the leaks. There's no active dripping, but it's covered in oily mud in the engine compartment... Vacuum gauge is also missing... figured maybe someone removed it and didn't plug the orifice, but can find any thing like that. Thought about just pressurizing the intake side of the hydraulic system to see where it leaks...</p></blockquote><p></p>
