First off Ive prob done over 20 rebuilds on super and other motors ..so not my first rodeo

Im helping another dude and got/taught him how to remove the seals and bearings...which he did while I was not actually looking

2 weeks later and we are reassembling and there on the bench is brass ring...about 2mm thick and the same size as the bearings and seals

logic says it must go between clutch seal and bearing?????

wtf?

no .its way bigger in diameter..almost the same diameter as the bearings and seals...slightly smaller actually as I can drop said ring into the area where the bearings sit .....and it MAY go..still not sure if it even belongs there

clues are that is brass... same colur as the brass in the cases where the bearing touches.

some one has said it goes under the clutch side bearing sandwiched between the Bearing and the clutch seal

i am in NZ and there is an urban myth that air conditioning units use the same bearings as vespa ..but are wee bit thinner by 2mm needing shim..but the bearing i pulled out is standard

aside..... there is true story of a dude being stranded and could only find air conditioning unit bearings for sale Which are 2mm thinner but otherwise identical...coke can shilm and he was away

Sooo back to brass ring we found..where the feck does it go.?

I think Speedys originals had something on the sides (like you described) that covered the balls... so you may be on to something there

hmm Has any one sighted one
thanks SEB..thats two opinions now that said brass ring goes tween clutch seal and bearing.
Strange...... I can recall over 20 separate vbc engines ive been inside and this ring is the first.

I will have to install it to see if the bearing sits flush in the case with it in place

I suppose its function is so the bearing seats on this brass ring rather than on the seal...and in following years the factory decided to leave it out to save $$$$$

can anyone confirm for sure that they have seen a brass ring 1 to 2 mm thick , same size as the bearing inside a VBC engine (super)

Have you got a photo? I'll see if I've got a matching part, as I've still got every bit of Speedy, & when i got it, the engine was original, never been touched, I don't think they even put oil in it!
Engine number? Speedy has 831XX & Speedys twin is 832XX (from memory).

BTW; Speedys Twin will be restored to original (N.Z. Airco version) using those parts

My VBC motor (1976) didn't have anything between the bearing and seal and it was the first time since factory that the engine had been apart (to the best of my knowledge). Having said that, I replaced the factory setup with DRT adapters and seals and this did have a few shims to get the spacing correct. Maybe if case tolerances were out, the factory used a shim to correct it?

Is it possible that this washer did not come from that motor ?
