In the first post, the first picture "existing bearing", you can see a piece of the casting backing onto the base of the tensioner.

Would it be any easier if you just drilled out the old, instead of cutting it off then drilling? Just wondering. I have a drill press, but not anything thin enough to get between.

Cutting the old idler off with a hacksaw takes no time at all, and is less messy than using a grinder. Punch out the old bolt and install new parts. Once I had the bolt installed had to trim the bolt head so it was flush, lots of material remaining to remove bolt later.

Wondering if they are new old stock.
If not what else uses them, & how much do they cost. :?:
If not n o s, makes things easier for many with limited tools,& shop space.

I suspect these are from a nissan vg20det but im not sure at all. The flange is slightly different, so the idler pulley sits a bit higher than the oem honda one, relative to the backing plate. I imagin you would need to adjust it a bit further towards the belt to set the tension, but thas not a big deal. Worse case the slot in the backing plate can be elongated to allow more adjustment if required.
