tensioner
 

I know magnuson sells the hd tensioner but if you go to the parts store can you just get an off the shelf hd tensioner? the a/c shop just broke mine and need one fast

While it's not the HD tensioner tha Magnacharger has available, the Gates 38131 Belt Tensioner Assembly has been determined to be slightly stronger than the original - Comes with a plastic smooth pulley. The radix supplied tensioner mounting bolt works fine. Removing the plastic sleeve from the locating pin is required. The pulley part number is: Gates 36100 Belt Tensioner Pulley. - Steel 75mm 6 Rib steel with 17mm bearing bore.

If you just need to locate something to get you going, the fitment for an replacement for the original are:
From 87-96 Ford F-Truck/E-Van 4.9L or 87-92 Bronco 4.9L
Dayco # 89222, Pulley # 89009
Napa, Gates, ACDelco # 38131
Four Seasons # 45869
Goodyear 49233

thanks....i did som digging and found an old one. This is the #1 reason I dont like other people working on my shit. the manager tried to argue with me no one was hot rodding my truck....I told him I had broken two of these and I only kow of one way to do it. The guy working on it later told me he had got on it " a little"..he said the truck got sideways on him and he got scared and let off the gas.

I hate to let people work on anything of mine for that reason. I hope they buy you a new one.

That's shitty. I would go blow up on the manager after he said that the truck wasn't hot rodded and tell him the guy admitted to getting it sideways. If I have to let anyone work on my truck I put the alarm in valet mode and it limits the motor to 3,000 RPM.
