VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 Intake Manifold Adapter Plate

I'm beginning work on my 1929 Ton and a Half Truck. It of course has the 6 cylinder stovebolt engine which I believe to be the original. The carburetor that was on it was not original so I bought a rebuilt one from The Filling Station. When I went to mount the new carb, it was rotated 40 degrees. On closer inspection, there seems to be an adapter plate mounted to the intake manifold that rotates the carb that 40 degrees. Or in other words, this plate bolts to the manifold holes that are rotated 40 degrees and then provides mounting holes that are in alignment front to rear. I'm assuming this plate was added to fit the carb that was on it and that I can simply take that adaptor plate off and be back to original position. Does that assumption sound right? Has anyone seen this?

sounds right, there were adaptor plates to fit aftermarket/ later year updraft carbs on the stock manifold assembly. the original 1929 would have been a Carter RJH-08 125S maybe a 136S for a late 1929 engine. and the carb actually bolted up to the exhaust manifold side and fed up through it into the intake manifold (warm up the mix going in)

I am running the Carter RJH-08 150S on my 1929, this is probably the most popular from 1930-1931, works great and runs great, as do the 125S & 136S.

You should be able to remove the adapter plate and hte Carter should bolt right up. here is a photo of my 1929 intake manifold with and without the Carter, notice the oval shape on the manifold, almost matches up perfectly to the carter mounting flange :)

That's perfect, thanks. So I took the plate off and yes, it is going to orient the carb with the truck nicely.

One more question, what would the intake filter have looked like and any idea where I could find one? I see you don't have one in your pic :)

i call it a vented tuna can...
I do have one, the engine picture was before i rebuilt the engine, it is now restored and back on the carb

Here are photos of mine after blasting and cleaning. these were empty hollow, later years they had a filament (kinda like steel wool) in them
the tube runs from the oil fill to the air filter, on late 1929. on the early 1929 it ran to the rear of the engine to the oil separator.

they are harder to find, and typically expensive if you can find one. each year 1929-31 were different !! may have a spare 1929, but i will have to look, may have sold it to a friend doing a restoration.

That is really good information BearsFan. And any lead on a "filter" and or Tube would be greatly appreciated.
And I do see the connection on the oil fill tube now. That make sense.

I will try to dig through my spare parts and pieces this weekend in between leaves :)
