Viton Output Shaft Seals?

[ksoholm]

Lads,

Regular nitrile seals are only good up to 210F, so I should go for viton seals for higher temp handling?

Also, whomever installed the layshaft oil seal used a smear of sealant on the outside - what do you fellers do? Dry or with sealant?

Thanks-

Dry and NBR is fine. If your crankcase gets above 100C you've got other things to worry about

Thanks, Rob - these things are well-cooled.

I oil the outside of the seal and the bore in the cases. It makes it a easier to install the seal.
