The center will just press out.

I’ve had one fail on me at around 80k and seen 2 others fail under 100k. It was new but had the smaller bearings and not the larger one. If they’re all that’s available I recommend changing them with the timing belt. I have changed the ones with the 17mm center due to them feeling dry but have never had one actually fail.

Steve, I may have a spare I can drop in the mail. I’ll have to check my stash.
That would be great Mark but don't go to a lot of effort. I'm sure at some point I will stumble upon a tensioner pulley with a 17mm insert.

Hmmmmm..... I’m curious what the 17mm one will log. Makes me want to look at one and see if it can be relubed.

At around $5 each, for the Uro, you’ll log 200k before you reach the cost of the Mustang part.

Todd, that's one manufacturer I don't trust at all for just about everything they sell. I think I have a flange somewhere by URO and I'm not excited about using it.
