How do I grease pto shaft slip joint?

[JKS3613]

I have a new Woods BB72x rotary cutter and one of the recommended maintenance procedures is to grease the slip joint in the telescoping pto shaft. The manual says to pull the two apart until just before they separate and then pack grease in the joint while repeatedly sliding shaft in and out to distribute the grease. My problem is the plastic shaft cover completely obscures the joint and I can't get to it to grease it. I also can't seem to figure out how to remove the plastic cover without pulling the shaft completely apart and that is what I am trying to avoid! Any advice will be much appreciated.

Skeets, I just fell on the floor laughing!! I love grease I re-greased my whole tractor when i got it. OMG the 3 point! the dealership must have never seen one before! I greased a lot, including the FEL now my pins are covered i see black all around the outside. i couldn't believe that one either. I came in the house and I looked like I was working in coal mine all day.

Thanks Skeets! I think I was over analyzing again. Lol So, as long as I put it back with the u joints in the same orientation, I'm fine correct?

You will find that the two halves of the shaft are made so you cannot put it back together out of phase.
Old shafts did not have this feature.

I slather never seize compound over the male half, and re-assemble. If it dries out, then I smear grease on it, to get it slidin smooth again. One Neverseizin, and 3-4 years a greasin, is about all they need...

PTO shafts are designed that you can't put them together wrong.

I dislike saying this but I oil in the shaft to tractor with WD-40 as it loosens up the ball bearings to go on tractor shaft. I have a grease gun and usually just use the grease in it. Last I Di separate the shafts to install shaft to tractor first to connect tiller.

There is usually an easy way to remove the plastic shield from the PTO shaft. On mine it is some plastic screw heads that turn in a cam movement to hold the shield to the bearing. Others have a lever to pop open.

I highly suggest that you learn how to take the shield loose since it will make disconnecting the PTO shaft from the tractor.

Once you know how to remove it, then you can get it out of the way to grease the PTO slip joint easily.

Two points regarding this post:

Perhaps the newer PTO shafts can't be reassembled incorrectly, but I know for certain the older square-tube type can and regularly are. Since I don't have anything new to go look at I'm a bit at a loss for specifics.

I do have one older Spanish-import (I think) that has a PTO shaft looks almost like a flattened figure-8---I know it only goes together one way because I spent more time than I care to admit beating on it before spouse appeared on scene and said try it the other way. What other way? Match the two big parts. D'Oh!

In my part of the world if you blow a U-joint and go to a driveline repair place or farm Co-Op store all you can get is the square-tube type shaft.

I dimpled with a punch the shafts to match just to keep U-joints in phase when reassembling.

As for lube, every season or so if I remember I squirt a little oil on the shafts where they join and work it a bit. If shafts get stuck (rust, grit) I've had to pull them apart with a chain-lever-hoist.

Please post back your continuing experiences so we may all learn.

Thanks everyone for all of the good advice. It turned out to be a pretty simple job after all. I uncoupled the shaft from the tractor, pulled the two halves apart, greased them, and as several of you mentioned, the shaft was made in such a way that it could only go back on the correct way, and that was it. Now I know. Thanks again everyone!!
