1020 RUH

IF a INTERNAL HYDRAULIC PUMP in the rear end on a 1968 high low RABBIT TURTLE SHIFTER ON THE DASH ON a 1020 John deere RUH , went bad. would it relieve oil in to the bellhousing or is there a relief port in side the bellhousing. Every thing is working on the tractor, ITS just puking and slinging HYDRAULIC oil out the bellhousing AND inspection grease plate. The tractor had issue when we got it , IT had a bad front hydro pump coupler on a brand new front pump. We fixed that . they had a check valve in the sucker side LINE FOR THE front pump AT THE inside REAR END HYDRAULIC HOUSING LINE PORT . caused the front hydro pump to wine and palsate bad in all the lines. The check valve should noT be in a hi low TRACTOR THE JD book says. so we took it out and it caused this. THE BOOK dont give a good image of wich line tie's in on the rear end for the front pump, THIS TRactor was SET UP SUCKER line ON THE INSIDE with check valve in rear end, and RETURN ON THE OUT SIDE ON THE rear end, any info might help . the check valve caused it to wine and hydro lines to palsate bad , no check valve sounded fine but it started puking hydro oil into the clutch bell

high low RABBIT TURTLE SHIFTER ON THE DASH is leaking into clutch housing.

what do i need to do tho fix this

Split tractor between engine & clutch housing to address oil leak.

pulsing hyd's problem[/quote]he check valve should noT be in a hi low TRACTOR THE JD book says

JD book- does this mean tech manual? I can't understand what would be difference in check valve installation on non hyd hi-lo verses a hyd hi-lo tractor. A check valve is similar to a diode as it allows oil to only travel one direction. The check valve I'm referring is part #s R39078,R39076, T23203 & D2361R and is in supply line that attaches to main hyd pump. Parts description only designates collar shift trans. in foot notes for these parts.

What's your tractor serial number?
