Used this product to replace the tensioner pulley on my 89 Toyota Supra. The design is different than OEM, but the effective dimensions (width and ribs) are the same. The pulley is lighter, and does not have a seating face for the bearing to be pressed against. I don't think this will be a problem, but it is an inferior design.

The bearing concerned me - it was not nearly as smooth as it should be. It felt like there was some debris in the seal or something. I used it anyways because I was in a time crunch and it felt alright once installed, but i'll be monitoring it. The OEM used a better quality bearing, but mine had too much radial play.

I'd use this part if you are in a bind and need it quick. Otherwise i'd order a higher quality replacement part.

            • Q:

              Does this include a mounting bolt for the pulley or just the pulley itself. My old bolt was rounded off, so actually had to hack saw it off, just to remove it. So just wondering.
              thanks.
