I'm installing a skid steer quick attach on an older loader and need to replace a couple pin collars. Anyone know of a place to order collars for 1" pins?

PRobably you could get something that would work for it at MCMaster-Carr. I would just gat a piece of heavy wall pipe and cut off and drill for the size pin I want to use holding the pin in.

Do you want just a reinforcing collar that does not have the pin keeper through it? If so, shaft collars from a hardware store, bearing supply house, McMaster-Carr, or equipment dealer will work. If you want the type that has holes for the pin keeper bolts in them, you might be able to drill the threaded set screw hole out and drill a second hole 180 degrees from it in a shaft collar for the keeper pin. Other than that, you will likely have to make your own as caterpillar guy suggested.

The correct term is pin boss.

There's two ways to go.
DOM tubing comes in outside diameters, with wall thickness specified.
1 1/2 DOM, 1/4" wall, will give a 1" inside diameter. (usually shy of one inch by a few thou)
If you own a lathe............either bore the DOM to .010-.005 oversize (1.010-1.005 inside diameter)
Or turn a 1" pin slightly undersize to fit the DOM.
Turning the pin is more cost effective if you have to go to a machine shop to have the work done.

I guess I might also add...................boring anything of consequential length, let's say 4-6" involves rigidity issues with the boring bar. Unless you're careful, it's possible to bore a taper.
To avoid a taper, take numerous spring passes. Sneak up on your final dimension.
If you turn a pin, plain ol' 1018 makes decent pins, despite what a lot of purists will tell ya. If kept greased, they wear well.
I built this FEL almost 25yrs ago, and the pins have done very well. 1018 cold roll.
Back when I built it, you could get oversized DOM from Shoup. It came .010 oversize. They don't sell it anymore. Was a great product for fabricators.
Anyways..........it was a fun project. I was teaching myself to weld back then. Doggone thing took almost an entire Winter to build LOL. All I had back then was a little Lincoln AC welder, O/A cutting rig, and a drill press.
I can't remember if they had digital cameras back then. All of the pics I have are 35mm film shots.
