I have a L3750 with a 4540A backhoe.

We are working on the backhoe. One of the pins on the bucket was frozen. We had to cut that one out and we were able to remove the other.

The pins measure 2" on calipers but this seems to be an odd size based on searching aftermarket buckets and etc. I also see some references to bushings in the parts provider listings.

What's up here?

Is the 2" pin correct and where would I source one (and also where does one find different size buckets for 2" pins)?

Or am I missing bushings to size pins down to 1.5"? Did they change from stock to smaller later?

Confused here and need some guru help!

Agree to legal. Put it your L4540A backhoe model.

Diagrams aren't good, but I think I see references and part numbers for bushings......

Yep - Wondering if they used 2" pins originally then went to bushings and 1.5" more standard size. A mystery to me what's what here!

Did you buy the backhoe used? If so, no telling what a previous owner might have done.
