Hi everyone We came across this bag 207786 with two seals in it. Can't find that part number in any of our books. The seals are national 50055. Can any of you find that number. Thanks

I have several National Seal cross reference books from the 80s and I can't find either of those numbers in any of them. I have an A-C cross reference book dated 12/31/97 and I can find neither of those numbers in it either. Hopefully someone else will have better luck.

In the oldest Master Number Index that I have, part # 207786 shows to be a shaft, not a seal and back then it was discontinued with no other notes. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

| Did you still have these seals. I pulled some out on a 615 tractor. From the rear axle seal behind brake drum. May be interested if you still have them. |
