Had posted a couple days ago about troubleshooting the hydraulics on my 1980 White 2-105. With hydraulic oil warmed up to 120
degrees and protractor on the pump. With remotes in neutral I have 1700 psi @ 1500 but no change on protractor. A good hydraulic
pump should move out of full stroke and show as movement on protractor. I put a hose on the case drain port on pump and at idle it
fills a quart container in 6 seconds. Put a pump on from a tractor with a blown engine. Second pump acts slightly better than first
with no movement on protractor and case drain pumps out a quart in 8 seconds. Is the case drain a valid test of pump condition? Any
suggestions, or comments appreciated. Steve

Normal or maximum is a quart in 15 seconds isn't it? The hyd oil in my 2-135 was overheating. The light would come on after an hour or so of work. When I did the case drain line test I filled a 5 gallon pail in 50 seconds. The hydraulics still worked normal though, so I'd say it's not a test for pressure or functionality. I put a new pump on it and the overheating stopped, but there was no change in how the hydraulics worked.

It has been a few years, but have you tried to adjust the compensator? how quiet is the pump in neutral? Send me an e-mail. J.
