That's not when it would leak.

what would you suggest to test it?

There is a procedure in the maintenance manual to pressurize the box. I'm camped about 30 miles north of Wonewoc so I have limited internet. It would leak when it is at operating temp and pressure with the seal assembly in a dynamic condition. Just get the shim pack exactly as it was and run it. If you fill it with oil you will make it hard to paint.

Thanks for your reply.  i am quite a while off sorting paint etc.  i will reassemble as all the gaskets and shims came off and when i get to the point of a test fit for everything, as it is having quite a few modifications, i will take the bike out and monitor how the bevel drive is in terms of leaks or any other nasty surprises.  if all is okay i can get on with paint etc.  cheers.

Just re-reading this and I don't think I see anyone mentioning this. Some smallblocks have a vent/filler on  top.  it is vital this is free.  It was Sign 216 that first brought it to my attention 150 years ago, and mine was blocked literally from new.  A good solvent degreaser should do the job.  Although mine hadn't started leaking, now, after a good long 500km ride I now find a faint oil mist around it.  If blocked it can pressurize the rear end and encourage oil past the seal

I am just waiting on a couple of parts before buttoning up the bevel drive.  Given that I have had to clean it thoroughly to ensure no tiny tiny metal bits interfere with its running, does the large bearing (U in the relevant workshop manual diagram) need to be repacked with any grease?  same goes for the roller bearing on the hollow shaft?  thanks

That's how my V50 III came from the factory: gasket/shim/gasket/shim/gasket. I use sealer (Permatex 300) and have no problem getting them back apart.

finally at a point whereby the joining of the cases is going to happen.  i ordered a gasket set and it came with three gaskets in it.  would this suggest that it should be gasket/shim/gasket/shim/gasket to avoid a metal shim to metal casing scenario?  thanks.
