    Clumsy Hidden Ujoint on RC2072 PTO shaft

    Surely this has been covered long ago, and if so I apologize but I can't find the thread.

    I just bought an RC2072 rotary cutter a few work-hours back, and I'm a guy who takes maintenance very seriously. So need-it-or-not I decided to grease the ujoints on the PTO shaft. No problem of course on the forward end of the shaft after dropping it off the PTO... but the aft end at the slip clutch is a whole other story. There's a big rubber(?) shroud that's in the way whichever I go. How are you supposed to access the zerk on the ujoint there?

    The rubber(?) shroud has access plates on each side which seemed the obvious answer but despite a lot of twisting and turning the access plates don't seem to help much. I can't believe JD expects to take the entire shaft loose aft of the slip clutch every time you want to lube a ujoint, and because of the way it's attached neither does it make sense to take the rubber(?) shroud off every time.

    Would someone who has cracked the code straighten me out?

    I have a RC2048, and it sounds/may be similar.

    The plastic or rubber shroud with the 2 access panels. Forget it.

    On mine, I pulled the front half of the PTO shaft off the rear and set it aside. The plastic shaft guard that covers the rear shaft (the one that has a chain, to be able to fasten it to keep it from rotating) has a screw holding the outer (black plastic) guard to a white, locking retainer, near the rear u-joint. Remove the screw and twist the shaft guard to get it to remove from the locking tab and pull it back. The u-joint grease zerk is now accessible.

    Hope this helps. I can post a picture later if you need.

    Kylew,
    I was having the same issue getting to that fitting near the clutch gear box u-joint. I read your post and removed 2 screws on my rc2048 and couldn't get the cover to release and move out of the way. Finally got frustrated and removed the 2 top bolts of the clutch shroud and pulled that forward enough to get the grease gun to the zerk. This wouldn't be my preferred method and think getting that shaft cover out of the way may still be the best option. Is there any thing additional to add to get the shaft cover to slide? It looks like there are white retaining tabs that may be holding it after removing the screws. Thanks

    They certainly don't make it very easy, especially on an implement that calls for grease with every use.

    Yes, the white retaining tabs hold the shafts outer cover. After removing the screw, twist the shaft cover a little to line up the slot in the cover with the tab, and you should be able to pull it forward. The first time I did mine it was stiff to rotate on the white tab part. I'll post a couple pictures in a few minutes.

    No doubt. The plastic shaft covers even have plastic grease zerks on them. I tried squirting grease into them and all it does is make a mess inside. Doesn't even get grease down the inner part of the shaft where it really needs to be.

    Cut a hole

    FWIW, my first solution was to take a 1.25 inch hole saw and cut a new access hole in the big bell-shaped shroud. It's still clumsy, but I can get to the zerk now without removing anything. I'm thinking that maybe a 90-degree grease fitting adapter may be helpful too, when I can get one, but so far it looks like this is always going to be a bad design issue? People who make maintenance hard to do just assure that maintenance won't get done.

    The plastic grease zerks on the shaft shroud are just for putting in a little lube to make the shroud easy to slide fore and aft, I think. Certainly wouldn't think those would need as much attention as the ones on the U-joints.
