You don't need to remove the grille casting, Jeff. You'll want the fan shroud off, but I can't remember if you'll want the radiator out or not. I just watched the guys in the shop do this, too! :wacko: CRS must be setting in. You'll probably end up taking the oil pump housing off the engine, sometimes those seals don't want to come out of there very easy. So, you might want two oil pump o-rings, p/n 675860C1, in addition to the crank seal.

You don't have to remove anything but the belts. Radiator and shroud stay in place, except on 1566/86 where the fan shroud is in the way.

1566 is the last tractor I saw this job done on, guess that's why I said take the shroud off.

I'll agree with just having to remove the belts and the pulley/balancer, but what's different on the 1566/86 that the shroud would be in the way? I've never had a front seal to replace on one of those, so I'm kinda' curious.....really figured they would be just like the 9/10/14's.

IH recommendations:

Flat rate time is 2.6 hours.

Procedure 4-100-D

1. Remove: Left front hood; Left side radiator support panel; Fan shroud (slide back); Fan belt; Fan; Left side radiator mounting bolts; Shroud.

2. Working through the left side, remove the oil pump "Body only".

3. Install new seal. Refer to GSS-1427.

4. Reassemble.

As others have said, most of this procedure is not necessary. I would recommend that the entire oil pump be removed to replace the second O-ring and also make sure no dirt gets trapped between the pump plate and front cover. With the proper tools and some experience the job takes about an hour.

Two upgrades were available that should be installed if your engine does not have them. One is a dust plate that bolts onto the damper pulley with the 3/8" bolts. It is used to keep dirt from being blown through the pulley into the seal. The second is a change to the woodruff key in the crankshaft. The standard key can slip while the pulley is being installed. If it does you will crack the pulley. The replacement key is longer. It extends over the crankshaft past the keyway in the shaft. If that key gets pushed out of place it comes out of the shaft rather than just getting turned. Small price to pay compared to a new damper pulley.
