Fan pulley question

Postby Ian D » Thu Jun 25, 2015 3:44 pm

Hello Folks
Can anyone tell me anything about the seals in the cub fan pulley assembly? I understand there is oil in it (or supposed to be) I put oil in mine but it just came out the shaft end where it mounts - I see TM list 2 gaskets for the fan pulley hub but are there not seals in there?
Regards
Ian

If oil is running out, you overfilled it and that gets messy when the fan blows the oil all over the motor! (a lesson I learned the hard way...). Turn the hub till the screw is facing towards the air cleaner, remove the screw, pump in some oil, then rotate the hole to the 6 o'clock position so the extra oil can drain out. Then replace the screw.

The full procedure is in the manual available at the top of the page.

Here is the 1965 Manual from RUDI'S MANUALS above. The Lubrication section begins on Page 63:

Originally there was a O ring type seal molded into the fan pulley assembly but there was never a replacement . In 1976 International went to a cast iron pulley assembly with sealed bearings. These are available from aftermarket. But its been my experience the aftermarket cast iron pulley bearings are junk. I always replace them with a quality bearing usually a timken
