Billet Aluminum Ultra Light Belt Tensioner Pulley

Just experimenting with a Billet Aluminum High Speed bearing Belt Tensioner Pulley. You get a nice new Pulley Bearing and Pulley diameter is only 3/16 inch larger than stock otherwise Pulley dimensions are identical to stock. The larger diameter will move the belt tensioner counterclockwise at the bearing center only 3/32 inch more which is insignificant ;)

To be installed and tested within a few days after I get Plenum back on my 90' (with some modifications to IH and Plenum of course :D)

This pulley is identical in Outside diameter and Shaft Diameter of original Alternator Pulley. I very thin washer (3/64 inch thick) was used between the pulley and the cooling fins of alternator for exact Pulley spacing.

Cliff,

Billet pulley on the way from UPR racing. Thanks again and I'll let you know if I need any help with the mod. Looking at your other post, I think I got it. :handshak: The billet aluminum alternator housings are done so I'll update how those are once I get them; not enough interest for a group buy.

Craig

I've run the Billet Aluminum Belt Tensioner Pulley now a couple weeks with absolutely NO issues :thumbsup:

UPR Racing replaced the pulley as I mentioned in PM and I received the new one yesterday so I'm good to go. Thanks for updating the prototype and I'll let you know how it goes when I get mine done.:handshak:

Great.....I expected UPR would replace the pulley :thumbsup:
Take a photo of the Billet Aluminum Belt Tensioner Pulley when you get it installed and let us know what you think.
Also...on that Aluminum Alternator Housing....let us know specifics or update your original thread when you get to it.

Just installed this Billet Aluminum Belt Tensioner Pulley on my 90' (L98). Works perfectly. Same minor modifications of Belt Tensioner Outer Collar as on LT5s ;)
