I am changing my clutch bell lining on my sceadu evo. After I clean out the old lining am I suppose to use rubber cement to adhere the new lining to the clutch bell ?

no, use 30minute epoxy (some will recommend JB Weld).

you want to make sure the liner is fully seated w/ NO gap.

take 2 wraps of electrical tape and wrap it around the clutch. Once
you glue in the liner, shove the wrapped clutch in to press the liner
into contact w/ bell. let sit overnight, remove clutch and tape.

z11355. That is exactly the way I do it. It makes the best seal, and it conforms to the way the clutch will fit.

And just use very little. Anice thin film is best, or you will have to scrape out the blob leftover.

Where's that EASY button?

yes, a nice thin film of adhesive cause otherwise, it's gonna squeeze
out.

also, put a small piece of tape over the bearing in the bell to keep
any glue off it.

also, it's easier to get the liner to fit if you shape (bend carefully)
into a sickle (crescent) shape. then put that in the bell and unbend
the crescent into a round.

Sounds good ! One more question before I try it. The lining overlaps. The cut needs to be perfect or will it melt or fill into the void if there is one ?

you want it flush- if it overlaps or is long it may cause a bulge on the liner-you definitly dont want it too short though as it will cause a gap-dry fit it first for a perfect fit and then glue it.

I do only one wrap of tape (after I put a little turtle wax on the clutch to keep epoxy from sticking).
After it cures I touch it up on a lathe so I have .006 thou. clearance

the 400004 liner will have to be cut. it MUST NOT overlap in any
form. Keep shortening it 1mm at a time until it fits w/o overlap
or a gap.
