TN75 Hydraulic Problem

[lowellcantrell]

Neighbor has TN75 with loader and 3 remotes. The hydraulics look up or vapor lock from time to time which disables the loader, lift arms, and remotes. We remove the plug on one of the pumps, start engine, move steering wheel to bleed, replace plug and everything works fine.

We have checked for leaks and can't find any. Any ideas why the hydraulics are locking up?

This is just a suggestion because I'm no expert on this tractor but I do know a little (very little) about hydraulics. Try looking at the suction side of the pump. Does the tractor have a filter on the suction side of the hydraulic pump? Replace the filter. Make sure the filter fits tight and does not allow any place for the pump to suck air. Check the fluid level.

Good luck.
