My neighbor just installed oliver loader on the 1650 that I replaced hydraulic pump on. He says when boom is raised the bucket curls at same time.Loader is connected to tractor remotes.I haven't checked it yet because he's out of town right now. Any suggestions on how to diagnose this?
 
Hyrdalectric I assume? Try adjusting the interlock bleed screws or restrictor valve screws.
I had a heck of a time getting the corn planter markers down one time after I had put a new pump in. I had to adjust the interlock bleed screws.
Don't pay any mind to the second picture. I should have looked at it and rotated it before I posted it.

I put gauges on couplers to test for pressure bleeding. On right side there was 2000 lbs on each coupler but only when handle was in corresponding position and not at same time.0n left remote there was 2000 lbs on top coupler with handle selected for it but bottom coupler had only 700 lbs when handle was selected for it and also not at same time. Do I have a stuck remote valve inside?
 
I'd sooner think a leak in the valve,wouldn't you? I never had to get in to one of those,but if there was an o-ring on a spool that was leaking by,that would let it bypass the oil so you lost pressure wouldn't it?
 
My guess would be a leaky valve. That would cause your loader problem. I have scans of the schematic and valve that may help. I don't se a way to attach a pdf file here so send me an email with your address and I'll send them to you. Anybody else who wants one is welcome.
