Cab 11 cowling seal

[Dave Schindel]

Hope someone can give me a quick tip on the fabric seal that runs along the front of the cab frame and seals to the tin cowling above the engine. it was held in place with steel nails driven right into the tin of the cab frame.What was originally used for the seal? Any help greatly appreciated.

Not sure which seals you mean, but from the attached first photo (I don't recall where this photo came from, so apologies for not giving the owner the recognition they deserve):

A: On my cab, this was a rubber 'P' section. But I've also seen a double beaded canvas, similar to that found on the top of the grille on a flat fender jeep.
B: Only ever seen this as the double beaded canvas as described in 'A'.
C: On my cab, this was a double beaded canvas as described in 'A'. But on an NOS front shell I picked up a while back, this was a rubber 'P' section (see second & third photos).

On page 154 of the January 1941 Chevrolet parts list, this 'anti-squeak' is listed as webbing (part no. 114286) or rubber (37852 R), so I guess both were used; strangely, only rubber is listed for the C15A. Not sure about Fords, but I assume similar?

Hope the above helps.

Owen.

Hi Owen

You ca't always trust what you see on the web or on a multi owner 1940 vehicle.

Basically cab 11 where built BEFORE the rubber crisis/shortage so yes rubber was used on all joint surfaces....... best substitute now is thin foam neoprene rubber with one side with adhesive....... it compresses well.

Mac Auto and other Chev outlets like Chev of the 40's do sell both the rubber and the double roll canvas similar to jeeps BUT I do not think that it will compress enough. The canvass antisqueak was prevalent on some cab 12 and most cab 13 and Mac has a good selection again with one side sticky..... which is a great help when installing....... webbing is also used on the brackets of the fuel tanks, fenders and various body panels.

Cheers

All good points. Advancements in technology over the past 70-odd years have undoubtedly provided improvements over what was used back then.
But again, I can think of some "improvements" that should never have happened!

The area I am talking about is at location A on the first pic. and the weatherstrip goes between the cab frame and the sheet metal.I will try to post a pic shortly.

Officially known as fender welts.... Flat rubber with one edge beaded...... so one and a half inch wide by 1/8 thick with a 1/4 inch bead on one side.

Available from most GM/Ford retro distributors.

My experience as been using a 1/8 foam neoprene about 1 inch wide easily found on EBay by the foot...... compresses and seals very well.
