Seals 98 rat

[SuperRat2110]

Hey guys, besides the crankshaft seal which protrudes a hair for the lube chamber, do the rest of the seals but right up to the bearing?

I set mine in flush with the case. I don't push them in till they touch the bearing.

[SuperRat2110]

Throwchain, is that personal preference or is that how they are typically installed. Are there any negatives to butting them up against the the bearing?

[thrownchain]

I'd say it's a personal preference, but been doing it that way for 40 years.

[SuperRat2110]

Ok, thanks for the advice.

With the already noted exception for the magneto side crankshaft seal, seals get pressed in to a point flush with the exterior of the case bosses.

There is nothing good which can come from pressing the seals in further than flush. (There may not be anything bad . . . but there is certainly nothing which is better by pressing in further.)
