PTO shaft U joint greasing

[aaluck]

Okay. Does anyone have a link to a grease fitting that will "easily" get into the 1/2 inch of space they leave us to grease the u joints on a PTO shaft? Or any tips on this?

I spent about an hour wrestling with one of mine this weekend and ended up with more grease on the zerk than inside the joint.

I have a LockNLube on my big gun (thank you to the forums, I LOVE that thing) and there is NO WAY it's fitting in there. So I'd like to use an old small grease gun with a "special" (maybe angled) fitting just for these U joints.

If it comes to it you can purchase an angled zerk and replace the (presumably) straight ones in the PTO shaft. 1/4" wrench should be all you need if I remember correctly.

I've got an adaptor fitting for the normal greasegun coupler. It has a 8mm tube, 5" long with a concave tip at the end and a small rubber seal in the tip.
It doesn't klick on the jerk. You have to push it slightly and nearly straight (angle 0-20°) against the jerk. Works great.

The first one I bought over 20 years ago for my Land-Rover (originaly designed for there prop-shafts) but I still use it for nearly all propeller shaft u-joints. Don't want to miss it.

I've got an ebay-link from Germany as an example. Maybe you can get something like that in the US. Or buy it here.

Simple. remove the PTO shaft and angle the joint so you have the room to grease. Do it all the time. I don't care for the lock and grease coupler or whatever it's called as most every grease couple is adjustable anyway.

Truer words have never been spoken.....but, sometimes I have it hooked up and just don't want to unhook it again. Plus on the back (implement side) I never unhook those and have the same problem.

With this coupler you won't need a separate grease gun for it AT THIS LINK Watch the video at bottom of page.

THANK YOU! Thats exactly what I'm looking for.

That should work perfect for my tight spots on the PTO shaft. Just placed an order for one, thanks for posting!

I also use Flips method, but I change implements fairly regularly

As I do but actually it has become less with two tractors now. Some of my driven implements are hard to grease anyway, the drivelines are heavy and long and have various joints as well. Some are constant velocity some are double Cardan and some are ordinary U joints and can be a mix of joints in one driveline depending on the implement.

Disconnecting the driveshaft from the PTO will allow the shaft to be laid-over to the side sufficiently to grease the implement-end U-joint. No need to disconnect both ends.

Exactly....

Of course, most quality drivelines will also have a zerk or two to grease the sliding halves as well.

I use a LNL on a 16 inch flex line and it works pretty good. It's harder to keep a rigid line at the correct angle in tight spaces i.e. U-joint on my zero turn is hard to get at.

I made an adapter using a standard screw-on zerk 3-jaw coupler and a 45 degree zerk fitting to get at a couple of tough to reach fittings on one of my machines.
