[Farmall] Farmall Cub Engine seal replacement

[Mike Sloane]

That isn't exactly true. The problem (as I understand it) is that IH 
machined the recess for the seal using an obsolete seal specification 
and never changed the machining (I am sure that Jim Becker and/or Ken 
Updike could explain it better). The new seal is very slightly smaller 
than the old. What I have done successfully is to use "flange sealer"  - 
Loctite 603, or the equivalent - to hold the seal in place 
<http://65.213.72.112/tds5/docs/603-EN.pdf>. It is an anaerobic, oil 
resistant, high temperature sealer that holds the rear seal very well. I 
have yet to have one fail in that application using that method. The 
only consideration with Loctite 603 is that it really needs about 24 
hours to properly cure.

I hope that helps,

Mike
