8000 PTO overhaul

[ford401]

Hi all, I have a DP 8000 with PTO that is spinning with it turned off. I assume it’s the brake band, but since i’m going in anyway I’ll overhaul the clutch. Question is, is it easier to do this all from taking the top cover off, or should I split the tractor? Any tips?

When I looked at my 8000 before purchasing, the PTO would not shut off. I wedged a 2x4 against the drawbar and then against the rotating shaft. My theory was if it stopped it was the brake; if it kept rotating the clutch pack was bad. Chewed up the 2x4 so I started ordering parts.
I did mine by pulling the hydraulic pump and going in from the right side. I pulled the rear wheel off too for some more working room. It was not the most efficient time-wise but it worked with the shop capabilities I had. I dropped a bolt and went fishing for it with a magnet. Not only found the bolt but also a bunch of needle bearings from the transmission. Job got a whole lot bigger at that point.

I have done this job several times and this is my take. The first one i was in i pulled the hydraulic pump manifold and went in there. Never again! By the time you wrestle the wheel and tire out on the axle and remove the linkages on the remote valves on top of the pump manifold so you can remove you, in my opinion are better off doing a rear split between the rear housing and transmission. Then, you can see what you are doing and easily get to the clutch pack, brake band and linkage. Of course i was working all the jacks, stands and a level floor which makes a huge difference. You gain nothing by removing the lift cover.

I’ve already got both axles stripped so I can replace leaky seals. i’ve done a couple pumps on 8000’s now and remember how difficult they were, i wasn’t even really considering trying through that small hole. It shouldn’t be too hard to split and push the front half forward.

There is a guy on youtube who did it through the top cover - that’s what made me consider that.

I'm pretty sure it's physically impossible to remove the PTO through the top cover. Are you sure you weren't looking at a 5000 video?

here is the link. the guy has a series of videos but in this one he pulls it out from the top.

I can remember studying the PTO and how accessible it was, when I split between the transmission and rear housing. I block the front and roll the rear.

I think splitting is the way to go then

Yes, block the front so that it can't flop over on you. Then roll the rear. Big tires roll more easily than small ones. Don't for get the 1/4 cap screw at the center rear of the hood. That one messed me up twice.

Well, I stand corrected, it is possible to pull the PTO out the back on an 8000. It would never happen on a TW though with the deeper PTO housing. Notice the guy didn't show himself disconnecting the oil line connecting to the control valve, that must have taken a LONG time. Then he had to separate the valve body from the housing before pulling it out. I'm sure it was no easy feat putting it back in that way.

I'd bet a week's salary I could split that tractor behind the transmission, service that PTO and have it back together in half the time that this guy fiddle farted around with his method. Stated another way, if he watched a video of me splitting it in half, he'd never do it his way again. That was painful to watch.

I roll out the front. Smooth tires roll easier than lumpy ones. Rear brakes and planetaries add drag also.
