After all machine work is done for the bearing mating surface "flatness" and aligning the thru-bore concentric and on-axis with the bearing I flip mount over in the lathe. Then I machine an o-ring groove in the top of the mount floor that surrounds the slotted nut and when o-ring gets compressed it seals the gap between slotted nut and mount bore. When cupped washer or one of the hardened spacers is slipped over the shocks threaded shaft and tightened down it compresses the o-ring a "planned" compression amount that forms a dust, dirt, debris and waterproof seal that "should" be water-proof to approx 100 meters if my math is correct.

The bearing from the factory has an internal seal on its pivot race on the bottom side and I press the bearing back into the mount using a long-life adhesive/sealant around the bearing so nothing can get inside and contaminate the bearings internals from either above or below the bearing.

Pics worth a thousand words so here ya go.

I don't understand what this if for. Care to enlighten me?

VAP

you cant understand basic mount "cleaning"... there's no way I could ever make you understand this.

CvTech

so this is all just to keep mounts clean and waterproofed?

VAP

seal is to prevent bearing dirt/water contamination "all" the other stuff is for other things

CvTech

and yes, now I do understand....pff.

I have to rock n roll lest I fall WAY behind ;-)
