Re: 41 Super 8 differential leak

Hi Wes,

The vent is clean and unfortunately the adjustment shaft is about 1" below the fill level plug! Now oil level is slightly below plug opening.

This morning I removed the "keeper"with curved slot that is held by a 5/16x1/2" long bolt and discovered 2 leaks- around the bolt and around the shaft. The locknut on the shaft was not tight.
Also a diagram in the 41 shop manual shows a blind hole for the 5/16" bolt. But it is clearly drilled through as gear oil flows with bolt removed.

So now everything is put back together. I rotated shaft clockwise until it stopped then backed off a few degrees then snugged locknut. Bolt is coated with teflon thread sealer.
Time will tell if leaks are fixed but I have no idea if the support roller has proper .005" clearance.
Not too thrilled about pulling axle shafts and removing differential.
