1650 Oliver gas Hydra power drive problem

Postby Tomn230 » Tue Sep 15, 2015 9:19 pm

Recently the hydra power drive part of my 1650 has been malfunctioning.
It drives fine but nothing changes when shifting from direct drive to hydra power. It will also free wheel down hill.
Any ideas would be appreciated
Thanks
Tommy

So if you have it in low range (knob pulled out) and you push in on the knob will the coupler speed up. Do this with tractor in neutral and see what happens. Do you have say a 300 PSI pressure gauge?

I see no visible change in speed from pushed in to pulled out. I do have a high pressure transmission gauge. Is there a port to check pressure.

On the right side of the unit is a small hose. Tee it in to that hose.
