Ford 8000 pto problem solved

Josh M. · Jul 18, 2021

For some reason Im unable to respond on my post from earlier, but I
pulled the pump off my tractor earlier today. I ran air through the little
metal pto line to test for leaks and found that when the pto was on,
air would leak from around number 15 where it meets with number 1.
When the pto is shut off the break band would tighten and air would
leak around number 29 on the pto valve. I pulled it out and found
super deep gouges on the brass bushing part of number 15 and
where the cast iron sealing rings are on 1. Looks like it ran without
oil, probably when the old pump went out, I know I shouldve checked
that the first time but I was racing against time before I had to head
back to school. Im getting parts ordered and a new seal for the pto
valve. 1 needs completely replaced and the only replacement I
found comes with an entirely refurbished clutch pack. My question is
that when the pto is off, should air have been able to leak around
number 29 on the pto valve? Im not sure if it leaking will prevent the
break band from being tightened enough or not.

You're going to have air leakage around all of those parts even when they're in new condition. That said, if your #15 support has super deep gouges, you've found your problem.

How do you like working through that little hole? The conventional wisdom around here is that it's just as much work to split the thing. And much less frustrating.

Being this is the second time Ive had it all apart, it honestly went pretty well. All said and done I probably had it apart in an hour and a half if that. I am kinda small and I can fit my hand and arms in there to get to everything. The first time doing it was a challenge, just since I had never even seen the inside of a tractor before. The biggest pain was trying to get that whole side cover off with the pump and the valves for the hydraulics. It got caught on something and its a tight space between the tire and the tractor to try and get everything out of the way while trying to hold that heavy thing. Not having any stands to split the tractor with kinda limits what I can do at the moment, eventually I want to make some and split that tractor in 3 and go through everything. Its definitely a project tractor. Right now Im just trying to get the pto figured out so I can dyno if I qualify in the tractor pull. Gonna be in the 12,500lb 115hp class at our county fair if I can get parts in time

That's a sharp looking 8000 for sure. Most of the ones I see are on their last legs.

With regards to pulling off the pump cover, I unbolt the valves from the cover and winch them up and out of the way with heavy wire, with the hoses and linkage still attached. Makes the cover and pump noticeably lighter.

Might have to try that when I throw it back together. Itll make lining that pump up a little easier. And yeah, I remember as a kid wanting my dad to buy that tractor. It always sat outside and one day I got the opportunity to buy it so I gave the guy some cash and drove it home. It looked pretty rough from being outside since 1991 or 92

Nice job on it Josh. I had a 9000 for 15 years for competition only. it had been in the weeds for 7 years before I got it. I sold it a few months ago. There are very few entries in the heavier classes anymore around here. I pulled it from 7,500 up to 13,000, although the most it ever weighed was 11,500.

Thank you. Im not sure what it weighs right now but it was 12,080
before I put the roll bar on.
