The Stovebolt Site Forums The Shop Area General Truck Talk PTO u-joint help

Greetings folks,

Shown in the picture below is the shaft that goes from the tranny mounted PTO to the hydraulic pump on my dump truck. A couple of the u-joints (one is circled) are shot and the u-joint itself can't be replaced, they are integral to the yokes.

Does anyone know who sells these? I would imagine they come in different configurations to adapt to different shaft diameters?

Any help would be greatly appreciated!!

Thanks, in advance!!

I see you live in Colorado Springs, which if I recall is a pretty good size town. So is there a drive shaft shop there? How about a truck bed supplier?

The u-joints should be only pressed in to the yoke, and I can see that the yokes are held in place by set screws. If the u-joint is part of the yoke, then they should have those or be able to get them, or if you have to they could make a new shaft to work on your truck.

burgie ...I,ve never seen one that had integral joints to the yokes,only fact. sealed units with no grease fittings. possible that p.o. welded them in. could have internal snap rings by the brg caps. if you cant get them apart with BFH and a vise, (heat wrench suggested), like Jolly sez, take whole shaft to a drive shaft shop or at least the joints off the shaft and they should be able to match up some thing for you steve sr. ps that looks like a std shaft to me.

What Jolly suggested... drive shaft shop... you could also ask around at 4x4 off road shops as when they get to modifying the ride height and things they have to have custom shafts made for strength/length or they modify the stock ones, depending on the situation.

my 2 cents.

Also try tractor supply houses, bush hogs, log splitters, etc. all use PTO shafts. Brian

Thanks for the feedback gang ...

I've done tons of u-joint replacements and I looked at the assembly, hoping I can merely pull it apart and replace the joint. But, I don't see any clips or retaining devices. In fact the journals on the bearing cups look like they are knurled, thus my description of being an "integral" part of the yokes...

Hopefully I can find some replacements. I don't need them now but always am on the prowl for parts

There should be a thin inside snap ring. The
u-joint kit is available at Carquest or Napa
stores if you can get a parts man to work with
you. The catalog has listings by demensions.

A place you might be able to find a joint like that is Granger. They carry alot of industial stuff like that.

OOPS I spelled it wrong, it is grainger. I looked on there web site, but did not find anything like that. Might be better off getting a catalog sent to your house.

The farm and fleet stores in our area carry a variety of PTO joints and shafts. I would give them a try,

Cool...finally found them on the McMaster-Carr website...

Thanks for the help folks!!

Check with an industrial bearing supplier, or a farm supply like Co-Op. Most of those joint assemblies aren't repairable, just replace the whole assembly. I notice the joint you've circled doesn't have much support. The pillow block bearing that supports the shaft should be very close to the u-joint, or the joint will fail very quickly. I maintained a fleet of wreckers with shaft-driven PTO winches, so I've seen that problem frequently!
