New Pivot Pin/Bushing - Too Loose?

Tom Bowman · May 16, 2014

I installed a new axle pivot pin and bushing in my TO-20.

The bushing and pivot fit tight when it was off the tractor, but when I reinstalled the axle carrier, pin and center axle section last night, it seemed like there was too much movement between the pin and bushing: when you grab one end of the axle center section and move it back and forth, you can "wiggle" it a little, toward the front and rear of the tractor.

How much play, if any, is OK? I'll post a couple of pictures. (Sorry, no video, so you can't see anything moving.)

I do know that it's a lot tighter than it was before. (Here are a couple of "before" pictures.)

when you get it all back together you wont have that movement

The radius links should keep that wiggle from happening once they
are in place.

Thanks, guys. I was hoping the radius rods would take care of that, but I wanted to make sure.

I keep the pivot bearing lubed on my old tractor
with a bottle of spray on graphite.

So far so good.

Tom. Out of curiosity, what is that rod or tube under the pivot pin? The TEA20 doesn't have it.

(The grease nipple - or I think you would call a "zerk" - was there when I bought the tractor in 1986.)

Incidentally, a good ride on lawn mower. I have an L110.

Bob, that's the hood safety catch, that was only used on some early TO-20s. The official Parts Book doesn't even have a picture of it any more, but Bob at FENA did some detective work and found an old Ferguson Parts Book that had it. (I think I have a copy that I can post.)

The John Deere mower belonged to my father. He started hiring his mowing out, so he asked me to "take care" of that machine. :wink: I just started using it this season.

Bob, would you believe the L110 you have was built in the factory I work in?

Jason S. · May 16, 2014

I'm glad you mentioned that Tom. I need to bring it to Bob's attention that he is wrong on that one. I now have two 1951 TO-20's with the hood latch that according to him is not supposed to be there. My tractors were produced roughly 10,000 tractors apart.

Bob (Aust) · May 16, 2014

I hadn't seen that catch probably because I only ever looked at one TO20 during a visit to my daughter in Texas. No TO20's in Australia!

No doubt I should thank Jason for building my very reliable JD L110 (with Kohler engine). :lol:

How's that "new" TO-20 coming along, Jason?
