The Stovebolt Site Forums The Shop Area Driveline Throw Out Bearing

I bought a new throw out bearing from my local NAPA for my 45 1.5 ton Chev it is a US made SKF #N1086-SA that is the long GM T.O. bearing that I have some times seen referred to as an 1 7/8" long bearing which is what my original is. Here is the thing, the new SKF bearing is the same size and fit as the original EXCEPT it is 3/16" of an inch shorter. It seems to me that I could easily make up for that with the clutch adjustment but being as the thing is so hard to get at when it is installed I'd like to get it right the first time. Should I be concerned?

Second question, although it has some grease from the factory should I pack this bearing before I install it ?

A little shorter is probably better than longer. Perhaps that release bearing is matched to height of the pressure-plate assembly?

The release bearings are most likely sealed and greased. I would not try to "pack them" with additional grease.

There are 2 different long brgs listed. One for the diaphram pressure plate & one for the finger type. Measure the distance from the front of the groove to the surface of the brg. That is the determining distance. Compare those dementions. It could be the variation in brands.
You can fill the groove in the center of the sleeve with grease but like TC says the brgs. are sealed.

Thanks for the help on this guys!
