Today I attempted, for my first time, to install the trans cover. I can say it was a real pain in the ***. Any reason why I couldn't ditch the felt and just use RTV along the top?

That is what I do, although I don't use ordinary RTV. I use a product called "The Right Stuff" which is a fiber reinforced RTV made specifically for this sort of application where a large gap needs to be filled with sealant only. Regular RTV can work OK but you need to be sure it has plenty of time to cure and that there are no voids caused by gravity.

I use the beer method in the shop also but it causes me to leak, not the car.

I massage a thick bead of black RTV into each side of the felt, so I virtually have a silicone gasket held together by the felt. I put the ends in place on the block and work the rest of the gasket down onto the land.

This means the thing stays in place when working on the cover.

Hope this helps.

I've used a bead of RTV on several and haven't had a leak yet.

I thought a good beer was "the right stuff".

I read a thread here a few years ago when I installed the hogshead on mine about using shellac with the felt. The idea was to saturate the felt in the shellac, let it dry a bit, then install while still fairly wet and sticky. Worked great for me. I suppose it's just another type of "sealant". Think I still have the can of shellac, as I bought it just for that purpose.

When installing the transmission cover RTV is a lifesaver. I use it to hold down the gaskets and the felt before sealing things up.
Years ago I would use grease to hold things in place.
Nowdays its RTV.

Thanks for all the input. I'm going to get some "right stuff" and try that. My biggest problem was I couldn't get the felt to compress enough to get the cover to block bolts on top to line up.

Jon:

The felt provided by the vendors may be too thick.

For you purists -

A seven page article "The Transmission Cover Felt" by Trent Boggess and Steve Coniff appeared in the May/June 2005 issue of "Vintage Ford."

The article includes the history of the felts as well as restoration tips.

The transmission cover felts, like all Model T Ford parts, were engineered/designed to certain specifications and drawings and memos exist for the felts.

It turns out that the hogshead felt supplied by the vendors is not made to the original specifications in that it is too thick. This can be remedied by carefully splitting the felt.

ALSO - depending on the year of the Model T, there were two types of shorter felts that were also used, an additional felt at the top of the crest between the hogshead and block and a felt under the transmission cover at each of the crankcase arms.

Interestingly enough, the Ford supplement in my 1917 edition of Dyke's Automobile and Gasoline Engine Enclopedia shows an "Edelman's" brand Model T Ford gasket set that includes the two shorter felts and lists their dimensions which are identical to those in the Ford factory drawings, including the specified 3/64" thickness.

Great video, Mike & Arkansas group. That is how we do it.

I especially like the 30.06 cartridge for a centering/alignment tool. That is what it looks like, anyway.

Great idea. And, it is just the right size.
