Re: about to rebuild a 650 motor , need advice .......,

you need the case half gasket!!!!!!!!!!!
















j/k, 1211 is fine. dont forget to grease the lips of the seals and put grease between the seals.

no grease on the outer edge of the seals, though...

Re: about to rebuild a 650 motor , need advice .......,

3 seals, starting from the fornt of the crank:-

1st is spring forward
2nd is spring forward
3rd is spring rearward (double lip seal)

So you see springs at both ends when installed...

That last pic should be where a seal goes... Looks like some corrosion... A small amount of 1211 when closing the cases should do the trick!

If I'm wrong I'm sure I'll be corrected swiftly! Probably by WB!

Sorry, now I get it! That's one of the centre bearings! Looks like some corrosion, and it may have spun a little at some point... I'd probably put a little loctite or 1211 on there during assembly...
