Skf cr6119 or 6120
What ones do we like ?
Available from the dealer still by chance ?

Page 1520 has some case bore chamfering info from ModifiedMark. You may want to do it first, to help the 6119 seals start in straight & easier.

Still can’t figure out how to go to an old page directly in the Stickies, but searching will do it.

I did a little searching, but everything is painfully slow lately. I’ll check that page out, thank ya kindly.

There's a step in the crankshaft at the seal pocket that the seal needs help to get over or the seal lip will turn inside out. For the 3400 to 4000 series saws I put a piece of 1/2" copper plumbing pipe over the crankshaft and push the seal over that and down over the step.

Failing that and for other saws that are similar, I wrap electrical tape around the crankshaft until it's built up to the same diameter as the step and push the seal down over that past the step.
Don't wrap any tape beyond the step as you don't want any tape under the seal lip once the seal is in place.

The Timken / National seals are typically a little larger than the SKF seals on the case OD. About 0.001" larger OD which can make them a little harder to get in. Both SKF and Timken / National work equally well.

SKF 6119 has one lip and the SKF 6120 has a sealing lip and a dust lip. Most of the old saws came without the dust lip so either is fine.

Backwards, SKF seal 6119 is dual lipped (HMSA1) & is preferred over the 6120 (HMS1) for dirty/dusty applications.

You made me go dig the spare seals out & look...lol

Just checking to see who's awake Randy. Well, really a mistake and it's not going to stop either.
Thanks for correcting that.
