Rear axle housing freeze plug, any idea why?

Post by Pep C Strebeck » Wed Sep 18, 2019 3:28 pm

I did not even pay any attention to it while I was pulling out the bearing sleeves, but someone had installed a freeze/Welch plug into the hole for the sleeve dimple.

Any ideas as to why someone would have installed these here? The axle was fitted with a set of Watts Seals.

That is a dome shaped plug used when you install 'modern' neoprene seal alum outer caps instead of the Ford felt and cup over the axle housing.

The plug keeps grease ooze of the Hyatt from sneaking around the neoprene o-rings in the modern cap.

Dan is correct. When I fitted the new seals to Henrietta, those plugs would not fit in the holes, so I just left them out and added some extra black silicone sealant.

By gum, someone figured out how to get those welch plug monsters into those little holes and expand 'em into place. See the punch marks?
I struggled with those little buggers and now I cannot recall what I did.
I believe I laid them in place and stuffed the modern cover on, over the top. :?
Since I lost my mind mind, I feel more liberated
