Dry clutch oil seal

Post by Peter Mille »

It's leaking ( again) on my Mille.
I remember from years ago, it was a real pita to get this seal in it's place.
Any tips on how to do this right?
I just ordered two new seals ( so I can mesh up at least one....).

I don't think there are a lot of Mille's out there so the reference base on the bevel dry clutches is tiny. I've never been inside one but if they are anything like the dry clutch belt models, pressing the seal in the cover is best done with a tool that engages the diameter of the seal so it doesn't cock or twist the seal as it goes in and the edges are uniform when in place. If it is being installed with the cover in place a cup type of driver will be needed so it clears the protrusion of the primary gear face that the clutch basket bolts to. I've used a flat plate to puh the seal in with the pri. cover off on my belt drive engines.

I concur with the last post, I have never had to deal with Mille dry clutches but the torque converter seal in my Mini caused me problems several times until I made a tool to install the seal squarely into the cover, large diameter seals seem to be particularly tricky

After a somewhat longer, fast run, the seal is oiltight again....(but for how long...??)
