Just a heads up on doing this. I ordered the seal, which comes with a speedi-sleeve to repair the seal surface on the damper from Advance Auto for my 7.3. Pulled everything apart, and sure enough there was a groove on the damper where the seal rides. I go to put the sleeve on, and no way is it going to drive on there. It's a lot thicker than the normal sleeve I am used to. So I have to gather it up and take it to work and put the damper in the lathe and cut it down about .120. The ID of the sleeve measure .125 smaller than the OD of the damper seal surface, so I left about .005 on the damper and drove it on with a soft mallet.

Just wanted to let you know if you are planning this job, and don't have access to a lathe, plan on taking it down to a machine shop to get the job completed.

 

Buy the seal at Ford then you would get the right one............

 

Sounds to me like they got the wrong speedi sleeve listed in their catalogue or the speedi sleeve they sent you was the wrong wrong one. Not sure if taking 0.120" of the diameter of the pulley would matter much to the strength of the pulley, probably not.

Seb....

 

The seal was correct. The sleeve was the correct OD for the ID of the seal. Was it the correct sleeve? I don't know. It was a Federal-Mogul seal kit with the sleeve and the seal all in one box.

 

I have seen more than one part in the wrong box.

I just went through a nightmare trying to get a heater for my 86.
I probably had to open 5 boxes to find one with the right heater core in it.

Parts book picture was right, number was right, core was wrong and did not look like the picture.
Yes the core did look like another one of the heater cores Ford used in 86, but the number should have been different.
