Rope Seal Alternative?

PostPost by: DJThom » Thu Sep 22, 2011 4:53 pm

Hello All:

I've read all the archives I could find regarding proper installation of a rope seal, including this one which was pretty comprehensive:

elan-archive-f16/assembly-rope-seal-engine-t9581.html

Key points being use the graphite type, 1/8" out on each end, don't press too hard on the seal surface.

In my most recent attempt I followed the advice, even made up a jig the same diamater as the crank to push the seal in radially so as to avoid point pressure. The result: fine at idle, but the first time I used the clutch it started leaking again. (end float OK).

I will try again, but before I do, has anyone used a modern rubber seal in this application? Is there one available on a modern engine that is the right size to fit our application?

Regards,
Darren

Darren, are you looking for something other than the obvious answer of ...why not convert everything over to the lip seal arrangement, which includes crank, pan, flywheel, maybe clutch, maybe oil pickup, seal carrier, etc.? I think what you're asking is, why not fit a modern seal in a lip seal carrier, that would seal the current 4 bolt crank?

Greg,

I'm going to keep my current setup, not worth converting. I'm just wondering whether there are any alternatives to the rope seal that have been tried, before I try another rope. If not, I will try again...
