Fan

There's absolutely nothing wrong with the direction you're going. You said you were going to rebuild it with a master kit. If it's the one with the heavy duty spring just be very careful with that. If you unbolt it without taking the proper precautions it will come apart very violently.

I don't think the kit has a spring replacement. It's just some orings, friction ring and some bolts.

How do I chk the fan hub for damage without having to remove it? I'm replacing the fan clutch and don't want to re-damage it if the fan hub is bad.

Spin it with the belt off. If the bearings are shot you'll hear a grinding noise or see a wobble to the fan. Also grab the Hub and wiggle it if there's excessive movement then the bearings are shot or the insides are worn out. If it's the Hub itself that's worn out just get a reman'ed or new hub. If it's the pulley hub bearings that are shot take it off the truck take the nut off, pull the snap ring off and tap the pulley off of the Hub. Those bearings are easy to replace. Just pound them out with a hammer and punch. For reinstalling watch how Rawze's does his wheel seal bearings on his YouTube video. You can do the same exact thing and it's highly recommended you heat the pulley and freeze the bearings to install. The pulley hub is made of a surprisingly soft Steel and won't take much of a hammer whack to mess it up.

As far as finding the pulley hub bearings just take the digit numbers and call up any bearing parts store and they should have a couple different choices for you to replace them. Oftentimes you won't find the exact manufacturer and part # of the bearing that came in the hub.

Update, replaced the fan clutch with a new borq warner and the fan is working great again. Thank you guys for the help.

Great job, thanks for coming back and giving us a update, that helps us when we have a similar problem. Often you'll see someone asking for help and comes back multiple times to ask questions and then the thread goes dead. When the original poster of a post comes back to share the "fix" to their problem it not only helps others but also says a big Thank You to those who helped in the tread. So again thanks.
