Ian,

22mm is correct. I just sold a NOS updated cover (for 22mm throw out
bearing) on eBay just recently, but I think Mark may have some too.

Hey All,

Ed and I tore into his Ambo engine yesterday. He had heard some things
that did not sound right...not to mention it was leaking from front and
back 35 year old seals.

Discovered was that one of the clutch plates had become unriveted from
the backing. The bike still operated smoothly but the plate was
disintegrating. Don't you love it when you find these things out at home
rather than 1500 miles from home? :-)

Also, as he disassembled...he noticed the 4 speed throw out bearing was
toast. The bearings were ok but the cage had disintegrated.

Questions: Anyone have a 4 speed throw out bearing to sell? The other
alternative is to rebore the opening and put the 5 speed needle bearing
type in there. Can someone confirm that he needs to bore the opening to
22mm.

Predicting that he would need to rebore we pulled the back end from the
4 speed. The insides were perfect. Amazing after 35 years! One thing we
noticed was a piece of metal at the top of the tranny....identified as
an "cup - oil pick up (12 20 20 00) Tavola 9 - #33". Anyone know why
that was put in there? It isn't in the 5 speeds and we were speculating.


Working on these Loops is so much fun...So easy.

...We'll keep you posted...Ian
