I have a 1915 Touring car, with the aluminium Hogs head. Naturally, it leaks a lot of oil out from around the steel shaft on the right side. Fixing it "properly" involves removing the hogs head, and machining a groove for an O ring or even bushing the hole. That is a lot of work, and time consuming. I came up with this quick fix idea, and made it on my lathe very quickly. And it has stopped my gushing oil leak completely, with little or no effort. I machined a blind cap, out of aluminium, with a flange on the open end. I bored the hole, in the cap, deeper than the shaft protrudes of the the case. I cleaned the surface of the hogs head with carb cleaner, lightly greased the shaft (to insure nothing would stick to it, and mixed up JB Weld, and smeared it on the face of the flange of the cap, and braced it in place with a block of wood, until the epoxy dried. This is the finished result. I drove the car yesterday evening, and the oil leak around the shaft has totally STOPPED. A stupid and simple, quick fix that does not involve major work. It worked so well, I thought I would pass the idea along for others.

Think you deserve an Award - Dam good idea - I love the solution!!!!!!!

hummmm i dont get it.more info?????.charley

oh i finally got it!!!!!!!!!!!!. charley

Wait a minute...what am I missing here? From the pic, I see what appears to be a totally enclosed cap, JB welded to the hogshead, keeping things tight and clean. So now how do you adjust the low band? What am I missing?

Or...is this an "optical illusion" given the angle, and it appears to be totally closed? I keep looking. That said, would oil still
eventually accumulate and still leak out? Basically it's a good idea...don't get me wrong!! Just being inquisitive is all!

No, it is not on the low band. On early cars the shaft for high gear comes through the aluminium hogs head on the right side. I understand that on later cars, that was not an open hole.

Tim, it's for the clutch fork shaft, early hogs heads had the hole for the shaft open on both sides.

When I ream alloy covers to take a thin wall bushing, I leave that end bush long so it protrudes some 3/8" . Into this I insert a cup type welch plug to seal the hole. Not something you can do in the car, but easy when the cover is off.

Thanks guys for the edification. Learn something every day

For those without machine shop capabilities: clean with carb cleaner & oil the shaft. A good bead of any automotive silicone around the shaft will form a really nice ( + pliable + easily removed & replaced if needed) seal. Works for me.
