Husqvarna Crank Seals
« on: March 15, 2013, 05:30:29 pm »
Can anyone here provide us the CR/SKF/National/etc industrial #'s for these Husqvarna crank seals?

503 26 02-04 as used on the 61/266/268/272 saws.  These saws use common 6202 bearings.

503 26 02-05 as used on the 281/288XP and 285/1100/2100/298/2101 saws (and probably others).  These saws use common 6203 bearings.  I have National 471466 and SKF 6904 numbers for another saw series (Poulan 4200-8500) that uses the 6203 bearings.  Those should work, as long as the seal body width is compatible.  Can anyone confirm this (or say it won't work)?

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

Tim (Fossil) figured out the 61-272 series seals.  That one is in my seals list.

Husqvarna 61-272XP

-FW & PTO seals: 503 26 02-04. National 15X26X6 metric seal (double lip like OEM). The size is the part #. I couldn't find an SKF that was 6mm wide. 7mm was the smallest in 15X26

Finding the OEM seals isn't the problem (for now anyway; Husky has been obsoleting 100/200 series parts).  I started this thread in hopes of finding industry replacements for the OEM seals.

The subject of seals can take on a life of it's own.I have as I've said before the master interchange book published by bearings inc.It must be 6 inches thick and weigh 10 pounds .I'm certain some place in that publication a match could be found but it's like finding a needle in a hay stack .

Best method to get correct seals is to measure the hole in the crankcase(o.D.),measure the crank diameter (I.D.),and measure the width of the seal.Go to a bearing supply store,they can get them overnight, but be sure to specify a "Double-lip" seal,or you will likely get a single lip seal- it will have the inside lip but not the outer lip.
Since the seal must hold against pressure and vacuum the 2 lips are more desirable.
And of course they cost much less than factory original...
