Derby cover. Gasket or o-ring?
In preparation of pulling my outer primary off so I can polish it, I bought an outer primary gasket, derby cover gasket and inspection cover gasket (where the shifter shaft passes through). When I pulled everything off, the derby cover had an o-ring and not a gasket. Should I reuse or replace that or, use the gasket. My TC has a gasket and seems to work well but, it's got five screws holding it on whereas my Evo only has three.

thats what I do. Just leave the O-ring in there and replace the gasket after it gets looking ratty.

You do have to make sure the o-ring is seated in the groove really well. The first time I buggered mine up because it wasn't in the groove and it leaked. When I removed the cover I realized the o-ring had slipped out of the groove and it was smashed. Couldn't see it with the cover on.

The new gasket is ****. MoCo felt the need to have some egghead redesign something that worked. When removing your durby covver be sure to mark it with a wax pencil or sim. They are almost allways warped and you should try to put it on the same way it came off. With my bike I allways reuse the o-ring or it will leak, and as above RTV is a must and she will be tight as a drum.
