I have a 190 xt that has hydraulic Pto engage and Power direct two speed that seems to have an hydraulic problem. About 6 years ago my dad was using it and the pto would slow down under load. He had it service by a mechanic and I think he rebuilt the seals in the pto assembly, it ran for several years although the steering was no where near as easy as before. A year ago he was no long able to steer the wheel so went unused. I "bought" it from him and did some pressure tests according to the service manual. I found on the first test for the steering, you unhook the hose from the steering valve and run through a flow meter, the steering worked great. My Bother repaired the PTO valve because that was the restriction, one of the spool valves was bent. Also found that the guy the fix the problem before had put 3 lock washers in the bypass spring for shims, I assume to bring the pressure up. When installed the steering worked much better but the pto would slow down or stop.. Yes I checked adjustment to make sure it was engaged. The pto has three position, Lock, free wheel and on.. it does not stop.
I went back to the pressure test. only getting 175 psi to the pto clutch and PD; it should be 290-300. So I either have a leak inside or no pressure.
I did the pressure test, between the outlet of the power steering valve and before the TEE going back to the pump and going to the PTO. Pressure should be 1200 psi with 4.5 gal per min. I have 5 gpm with no pressure and at 1200 psi I have about half gpm. Does that indicate a pump problem.. Or does someone here have way more wisdom than I.
sorry for the book, trying to give all the info. Thanks
