Hoping that someone has some insight into this PTO issue. Bought this a few months back, 1955-2516xx, had some issues with the hydraulics, which case they have all been resolved. Started with the fact someone replaced the unloading valve, and the excess Teflon tape was all bound up in the pressure valve (s) spools. Removed and cleaned, replaced all the O-rings, run the tests and pressure's were reset, low pressure side as well. Thought maybe this was a cure for the PTO to be able to be stopped by hand. No help. Teed a gauge in at the pressure line on the PTO valve, plugged the return line to the reservoir, engage the PTO, had 0 lbs pressure. Found that the pressure line that feeds the junction block on the low pressure side had rubbed on a cooler line, wore a hole but didn't leak to the outside. Replace the line, now have 240 psi at the valve teed in, still won't run. Valve engages the clutch, minor leakage from the return line when engaged, and the brake will hold when applied. Pulled the pto, pulled it all down. Clutch discs looked as "new", and measure within new specs, both friction and the steel. Thrust bearing and plates show "0" wear, not even a wear pattern. Did a mag particle on the clutch and brake housing, no cracks or holes.
Have reassembled the darn thing, but I haven't really fixed anything, so where do I go from here? Don't really want to put it back in knowing nothings changed. pretty sure I must have missed something simple, so maybe someone can point out where I went wrong. It is 2 speed, and in 540 with 540 shaft now.
