I have a 20? Year old Honda 750 tiller. A beautiful machine, but the bearings in the tensioner pulley for the drive belt. seized up. So I need one of these:
Honda 22465-777-003 Roller Tensioner part 5 in diagram
I’ve looked at several dozen online parts stores and the parts diagrams all say

roughly “no longer in production”. Ordered several from smaller engine repair places hoping for NOS, Amazon, eBay and etc, They decide they dont have it/can’t get it and let me know that after a month.
Emailed Honda & they wouldn’t help but said see your local dealer. There’s only one within driving distance & they only do parts as a sideline and don’t stock much, I’ll drive over and try but I’m not hopeful they can come up with an alternative. Last time I had to special order parts which turned out to be wrong
The pulley is stuck on it’s shaft — I can get it off with my oxy torch, but didn’t want to damage it until I have a plan
I could drill the spot welds out and see if I can find a matching bearing set. But then I have to figure out how to put it back together & bearings may not like welding/brazing going on.
I thought somebody might have an idea on how to repair or for an online vendor who could look at a dimensioned sketch and suggest another part. I have a small lathe but am not good at making stuff like this
All thoughts appreciated!
