Not sure your purpose....

Flywheels have a purpose of keeping momentum. Less you are really building a drag/circle motor, keep some rotating mass.

.

Please correct me if I am wrong (something that I don't have first hand experience with) but won't the '39 flywheel put the ring gear in the wrong location requiring further modifications to make everything work?

I intend to put an A transmition behind this and put it in a stock A car. seems like this is the easiest way, to mod the pan, and use the A bellhousing( flywheel cover) inplace of the B one?

im wanting to run the B flywheel, which from what I have learned should be fine with the rest of the A parts

I cut off the back of the pan and ran a Model A flywheel housing in my '31 RDPU as I thought it was the easiest way. I may have used a B flywheel but I don't remember.

Regarding the oil passage along the side of the block. No, it does not pass oil to the valve chamber, it sends the oil to the mains and cam bearings. I'm not sure if one gets the oil before the other, I don't have a 4 cyl here.

thanks, I did actually read that someplace after I posted this

from what I have learned and read so far, you are wrong about the preasure oiling to the mains.

i believe they get pressure to the mains, and not the rods. excess oil is dumped out the front of the oil galley thru a hole into the back of the timing gear. some folks thread that hole then put in a plug with a smaller orifice to raise up the oil pressure. v8 style pressure plate and clutch is a nice mod for lighter pressure required on the clutch pedal. happy motoring

good to know

Beater · 08-31-2019, 12:37 PM

ok, next question,if anyone knows. to me it looks like the spaceing of the B and A flywheel housing are the same. is there any reason you cant leave the B oilpan / flywheel housing alone and still bolt on an A bellhouseing and trans?

No provision for rear motor mounts.

well id have to disagree, mine has mounts just like the A on the top cast part. you can see them in the pictures unless they are in a different position than the A?

Charlie Stephens

going to go into a 30-31 A car eventually

looks like I have the long pump

Beater · 08-31-2019, 04:54 PM

got pan and flywheel off anyways. things look good washed it out with degreaser and cleaned it up some pan and flywheel need to go to the hottank really.

isn't that balanced crank prity prity

What you are look at and thinking they are rear motor mounts are actually provisions for brackets for the anti chatter rods used in '32 (and up for several years). They are in a slightly different location from the pads for the rear motor mounts on a Model A. You could probably make brackets for the rear motor mounts and bolt them there.

Heck, I'd try to use the B transmission. At least it has a synchronizer for 2nd & high gear. The drive shaft might need to be shortened though but it's do-able. The pedals is where the problem lies but it can also be worked around if a person wanted to go that route.

ok, thanks, I just assumed that this was the same as the A

I wonder if the B gears will go in the A case?

cas3 · 08-31-2019, 08:41 PM

no, but late style v8 gears will go in a b case. clings make a set up to mount pedals and wish bone, i made my own once, still have the jig for locating the pedal shaft

Beater · 08-31-2019, 09:02 PM

interesting. I have 2 B transmitions, but have no idea what they look like inside, where I have a ton of A stuff. think it will still get an A trans behind it

Great post; The Aftermarket Model A pedal bracket is a nice piece and makes the later transmissions a joy to drive. Newc
