TO30 Hydraulic Pump Concerns

Militaryman · Nov 18, 2014

I bought this to30 back in July, hydraulics not working, not an issue. I'm rebuilding the hydraulic pump, once I dropped the pump, I noticed that the pump pistons were broken and the cam blocks had disintegrated, not sure what caused the issue. I'm hoping rebuildong the pump and the lift will do the trick.

Any thoughts?

Probably was started while frozen. Be sure to clean the sump best you can before going back together.

Replace the relief valve also if it's not in your rebuild kit. Very important.

Thanks for the input Guys, any input on what type of oil to put back in the system. I've seen different opinions on this site, not sure what to go back with.

I use 90 wt. what the factory used. Others use 15-40 motor oil. If your in very cold weather you may want to use the motor oil. I'm in Tx and its hot. LOL
