Thanks so much for finding that part number. I'll call the dealer tomorrow! Seems common across several models. Maybe they'll stock it.

I could see a couple of inexpensive options;
1) Are the holes in both ears the same diameter?
If so a large bolt the proper diameter, with a nut and washer.
2) It looks like a 3 point bushing might be the right diameter with a bolt thru it.
3) There should be minimal side loading on that pin, use a thread file or die and get the threads cleaned up and then use a nyloc nut.

4) Or it may be this part number TB44360000A4 [BOLT] which is around $20.

Luck

I've had a thought of replacing those bolts on my tractor with a heavy pin with lynch pin keepers to avoid needing a wrench to swap my 3PH with my backhoe. Any reason that needs to be a bolt w/ nut instead of a pin?

It looks as if there's a flat on one of the ears to prevent it from turning, that might be in the way. I wouldn't want it to turn while in use neither, I think it'd be more prone to wearing the ears, just my thoughts.............Mike

Looks like a shoulder bolt to me. Might try the hardware store and see if they have that size.

I think the flat just makes it so you don't need two wrenches. Not sure why a pin would spin with either a backhoe or a 3ph lower arm on it.

I've thought about replacing them too. Can't see any problems if you find the right size.

Post #9 well do the job.

A reason to use the factory bolt that sits against the shoulder or pins with retaining eyes is to reduce the wear on the bolt holes.
As the 3 point is raised and lowered the swivel ball is rotating around the pin the wear points are the pin which is held stationary and the swivel ball which can be replaced,
if you let the pin / bolt rotate the bolt holes will become the wear point, many times the bolt locations are not easily replaced or are part of the main casting.

That was my point in post #13 also. yes, the balls are supposed to turn...key word 'supposed' :).............mike
