I welded my pulley to stop it from slipping over 10 years 100,000 miles ago & it is still going strong. My tensioner is still original over 200k miles on it & belt still good over 100k miles later. Never reinstall one of those pulleys new or used because it will fail before 60K, leave you stranded & you will have to do this job over again. You can also buy a solid pulley instead of that original junky one. Just 2 small welds across from each-other between the face of the pulley.& arbor. Cost under $1 + labor.
was upgrading to billet aluminum and just got a new alternator and alternator pulley was an option that was solid and i was like hmmm, whats this "free up strain on motor". Uhhh ill keep this because my alternator is a PAIN to get to, have to pretty much pull the motor since bolts are to long. I also would love to keep my new tensioner in good shape and my belt since its my waterpump too lol. Thanks for confirming my curiosity.
How long until we start seeing retrofit kits for cars not equipped from the factory with ADPs? If the OEs are including them from the factory, it stands to reason that they're effective in doing what they're designed to do. I'd certainly be interested if the option ever becomes available. It also begs the question, how does the rotating mass compare to a traditional solid pulley? The performance aftermarket pays good money for lightened and underdrive pulleys, but is there a performance benefit to using an ADP instead?
We have a couple of retrofit kits out there now. One fits Ford police cars (39189K1) and the other Toyota (39068K1). Both of these belt drive systems are vastly improved by using the Gates Enhancement kit. The benefit of using an ADP is lower belt tension, not weight savings. By lowering the belt tension, this reduces the parasitic losses in the belt drive, thereby improving fuel economy. This also reduces the bearing load on the accessories which increases the life of those accessories.

well said jimmy, I love my solid alternator pulley, no problems.
We're loving the conversations this video is generating. Keep it up!
I've seen nothing but problems from them, seen 4 or 5 failures on cars I have worked on this year. I'm glad my car uses a basic pulley.
Great explanation of how these work, and why they were invented.

Thank you very much! :)
not true when doing coyote swap first steps is change pulley with solid one hahah and it works perfect
