SKF Seals
« on: June 04, 2015, 08:57:49 am »
need to replace seals on my Dayton 2Z463B (Poulan 245SA). I've found some PTO Inner seals on SKF site - 721570 and 711807. they're both

Description - BLOCK VEE SEAL
Lip Code - Longlife (Fluoroelastomers) (Lip Code: V)
Type/Style - BV

sizes match up pretty well but I don't know squat about materials. the SKF site indicates the fluoroelastomers can withstand fuel and temps up to 490F. any of yall had any experience with these materials?

That material is better know as Viton. Better chemical resistance than Buna rubber seals , more $$ too.

I'm not sure that a V seal is the correct application but I'm not sure.

Just so you know, there is a substitute for the 306 / 245 PTO side seal.

Poulan 245/306

-PTO seal: 530001936. Dichtomatik 068091VM (dist by Rankin Industries). .687"x.937"x.135" (OEM measurements). .688"x.938"x.172" (AM measurements. Suitable).

Many chainsaws use a double lip seal.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
