PTO Noise Help

[9mules]

I installed a new rotary mower pulley and everything appeared fine. It spun etc.
Tried pumping some grease onto the fitting and it broken clean off!
I engaged the PTO (I had to show my new toy off to my best friend) and it made an awful racket. It spun good before I quickly disengaged the PTO.

1. Inspection of the grease fitting hole reveals no threads. Looked smooth as far as I can see which ain't much that's a small hole even under a magnifier
2. Could a piece of the fitting fell down into the bearing?
3. I've researched the site and Rudy's and I'm ready to tear into it but I want some opinions on this before I do.
Thanks,

The grease fitting is a driven type fitting, there are no threads. So most likely, it just broke off and nothing has fallen inside as the remains of the fitting are still in the hole. The most common cause of pto noise is the shift collar not fully engaging allowing the shaft to slip inside the partially engaged collar. Or from worn bearings or bushings. Since you're ready to tackle this, go ahead and remove the pto shaft and see what the problem is so you can repair it correctly. It's not a difficult job.

that fitting doesn't really need greased unless you are using the pto a lot when the tracotr is not moving, otherwise it is lubed by splash form the differential. What kind of mower do you have? Teh 42 inch rotartys with the swinging blades sometimes make a lot of noise untill they get up enough speed for the baldes to stay swung out.

I didn't know there was such a thing as a press-fit grease fitting...

I think all of mine on the Cub are threaded, most likely thanks to a previous owner. But I noticed that there's one or two missing on my IH-1000. The holes are not threaded so I assumed they had been stripped (albeit extraordinarily cleanly, I thought to myself), so is this the same situation?

Allen, press in fittings are quite common.

Big Dog,
Thanks for the help. I figured out my PTO noise.

The grease fitting is a press in.

I figured that out by looking at page Section 6A page 5 in the Power Take-off Belt Pulley GSS-1411 Service Manual.

The drawing is excellent.

Thanks again.

Hi John

Thats nice to know as I have been greasing my pto every time I mow. And I was starting to wonder if I was going to end up with a glob a grease laying in the bottom of my trans.
