Info needed: F30 grease seals ?

[Phil Waterman]

Hi Rob

I was speaking of one in Lynn's picture but the outer seals under the wheel axle shafts nut are missing from that truck (Pattern 12 C60L ) as there was no seal lip was left.

As to over packing wheel bearings, I agree, you and I have both seen wheel hubs were the entire hub between the bearings was packed solid with grease, which is an invatation for grease getting where it should not. My extremely well packed is being sure to fill the spaces between all the rollers.

It really just boils how steep a cross slope you want to drive or park the truck on. Sure would not want do any mud bogging or deep water fording with out the seal in the picture.

At the time I found the seal sitting on the shelf I had been working on all three CMPs so I didn't have a clue which truck or which wheel it was missing from. Figured that a little driving and it would become evident, it never did. Wasn't until five or so years later, when doing preventive maintenance that I found which wheel.

Cheers Phil
