[AT] The IHC W-4 front oil seal

[Dudley Rupert]

Roy,

The first thing you'll need is good access to the lower front of the engine;
e.g., remove the Grill, the radiator, etc.
The next is to remove the Fan Drive Pulley on the front of the Crankshaft
(Remove the big Nut holding the pulley on the Crank and remove the Fan Belt;
Note: A Gear Puller may be needed to get the pulley off).
The next is to remove the gazillion cap screws holding the Crankcase Front
Cover on and Remove the Cover.
The Front Crankshaft Oil Seal (IH P/N: 53 888D) is in the Cover and the
Cover Gasket is IH P/N: 352 169 R2 (which you will need).  I think your'
Case IH Dealer will have, or can quickly get, the seal and gasket.  I've
done this job on the Farmall H engine, which I think is the same as the W4
engine, so I think the above recipe will work (hopefully I didn't leave
anything out).

As to whether or not this is a tough job I will let you be the judge.

Good Luck

Folks,

I suspect my front main oil seal is leaking.  It's been toooo cold to
investigate completely (near 10F tonight), but there's oil behind the
radiator below the fan belt area.

I trust this seal is not impossible to change.  I also don't see any
mention in the manual about tightening any retainer ring or the like,
in the way the water pump seal can be.

Anyone remember how tough it is to fix this?  And what's a likely
source for the seal?  (it's leather.)

Roy
