Postby 61Cub51 » Sat Jan 25, 2014 6:36 pm

Ive got a Cub Cadet Original 1961 Model and Im working on changing out the bearing and seal. What are the replacement Numbers for these two Items. And What size pulley Can I put on the end of the drive shaft to speed the transmission up just a little . ( Parade reasons) Thanks Matt

I believe you are looking for these:

21 IH-377959-R91 Oil Seal, Reduction Drive Shaft
And unfortunately (NLA):
18 ~NLA Bearing, Reduction Drive Shaft Front

But, look at diagram to verify it is what you were wanting:

I am sure one can be matched up at a good parts supplier.

OH, good looking O, like the fenders!

Good luck,

NAPA lists NOS 7636 as an interchange for the #21 seal.

Take the #18 bearing to a good bearing supply house in Raleigh and they may be able to fix you up.
