Hydra power drive slipping

bv · Sep 26, 2016

If you have a hydra power drive slipping in high range but not low range and is full of oil what is the problem, can they suck air in the lines or what is the potential problem?

Check your direct drive pressure first. Does your clutch have free travel?

Yes the clutch has free travel, what should the pressure be?

Not sure what model tractor you are having problems with but my manual for a White 2-105/2-135/2-155 states the pressures for the direct and over drive should be between 140 and 160 pounds.

The test ports are to the rear of the oil filter on the side cover. The one nearest to the filter is for the direct drive and the one further to the back of the unite is for the over drive according to the manual.

There is a lubrication test procedure as well which states that pressure should be 27 to 33 pounds.

Hopefully this info is helpful. If pictures would help identify these ports I can get some tomorrow since my over under drive is out of the tractor right now.

Same idea, but a Hydra Power is different than an Over-Under.

I'm not at home right now to check the manual but I recall 300 psi in high and 40 in low for 1550.
