Bearings & Seals for B-12 wheels

<< < (2/3) > >>

the old trucker:
   I found National seals pretty good also. Another brand I used was called Chicago Rawhide & Stemco is another. I think Chicago Rawhide had one with a grit gard feature. It worked really well for me on trucks.

Averyman:
Cranman.. Is that  drive axle seal (National #5797) a one piece unit with the seal permanantly mounted in a flange with  five bolt holes in it?
NAPA advises it is no longer available from National  but CR advises that they will in future be manufacturing a replacement under #20380. (They could'nt give a date though)  What year is your machine,just want to make sure we're talking about the same seal.

Cranman:

Mine is an early 1953 (January) but is still old style early metal, like the 1952 with wood doors and aluminum sprockets etc so the part numbers will be the same. Too bad you can't find the National but I'm sure the CR will do the job. Maybe give Dan Shaver a call or email some other suppliers. There must still be some on the shelf somewhere. Good luck.

the old trucker:
  I found a place, www.canadianbearings.com. They are in Toronto, ON. Don't know if they can help any.

Averyman:
I got around the outer drive axel seal problem by chucking the flange in a lathe and machining off the dimples that held the origional seal in place. Then I pressed a CR#20526 into the flange. Not as robust a seal as the origional but it works fine.  National #5797 and CR#20380 are unavailable through NAPA. Cranman... my machine has heavy cast steel drive sprockets.
