•••BUILD THREAD: SUGAR CITY SPL 1933 Ford Comp Coupe ROAD To ROG•••

5/16" High Dome Rivets are the ones I need for the saddle. Thanks Scoots!

 

Technical questions.

Here are the parts that I am using for my rear end.

1935 Ford rear end with 4.11 Gear
1935 Ford Rear Radius Rods
1935 Torque Tube
1933 Drive Shaft.
1935 Ford Transmission case with later gears hopefully

Now I have a set of 3.78's out of a '39 Banjo that I eventually planned on using when I had the scratch for a quickchange. I know the '35 rear is a bit different then the 39 but will the distance from the R&P to the trans be the same when I swap them out? Or should I go ahead and swap in the 3.78's now and cut the driveshaft to fit it right off the bat?

 

I do not think you can put 37-later gears in a 36-earlier banjo. The pinion shaft size, length and such are totally different (I'm nearly sure anyways). The inner bearings that go on the inside of the bells are different too, I think. I think you need to stick with 35-36 gears.

 

The banjo housing carries the Ford part number from 35-48 so while the guts are different the housing should be a direct swap. Now the bells carrying a different bearing might be an issue.

Well gears are definitely different. THe internal difference of the spiders with the early rears using 12 tooth spiders and then later using 11 tooth so yeah that's definitely a different animal. But if the housings are the same from 35-48 I should be able to put a 1939 R&P into the '35 housing but if I have to swap out axles and the bells won't work due to bearing issues then I need to find a set of 3.78's for a '35.

 

I would say 39 r&p fits in a 35 rear.......
39 might be 6 spline instead of 10 spline

35-36 bell bearings are special, but will fit later gear , diff housing

Just exchange the r&p

I would look for a 46-48 banjo section with 3.54 gears in it

 

Diff housing will fit from 32-48 ring gear

That is what i said

Keep everything 35 , but the r&p (use the 39)

 

yup.

 

So that means you can use 35-36 R&P in a 37-up? I have a mint 3.54 gear set for both 35-36 and 37-48.

 

Just reaffirming....

What would be best for a quickchange? 35-36 R&P or a later?

 

Rodsville says

Is would it suffice to say that the 35-36 rears are not intended for Quickies? At least not the quickchange cases that are being reproduced today?

 

You just can't use the R&P from 35-36 in a QC because they are 10 spline. They are the same width as 37-41, so you could feasibly use a mixture of parts but the easiest way would be: Take your complete 35-36 axle assy, (cones, axles, spiders, carrier, and bearings) put the R&P on the shelf, find a nice 37-48 R&P and have it machined for the QC. Assemble. Done.

Other thing to consider when changing to a QC center: The input of the driveshaft/TT is lower... so you will need to modify your radius rods after installing the QC center.

 

Awesome car great work. Keep it up. Need to stop by and see it. My roadster is getting there.

 

Oh ok. But I suppose if you were using a '34 Driveshaft like I am you could! Anyways, I'm going to dump the 3.78's from the '39 and machine a coupler for the driveshaft when I cut it down. The real question is where did I put that money I had for the Cyclone Quickchange.....oh yeah I had kids!

 

No, you can't because the pinion faces the rear of the unit and is driven by 6 spline spur gears. You NEED a 6 spline R&P for a V8 QC. You can use a 10 spline driveshaft, but you'd need a lower shaft with a 10 spline input or 6/10 adaptor.

OR... you could weld a 6 spline end into the '34 driveshaft.

 

oh yea... frame looks great too!

 

You're so smart. Thanks dude that totally makes sense.

 

Never done it, but I don't see why not. I've got a Rodsville rear with '41 R&P and 35-36 guts/axles/cones mocked up on the bench right now and it goes together fine. If it goes one way, it should go the other right?

As long as you're using the correct carrier bearings/races for your cones and the corresponding spider gears for your axle tooth count, smooth sailing.

 

No......
I have a 36 rear axle with a winters qc center section under my 32 .....

I'm surprised that only a few american traditional hot rodders know about
Banjo rears.....

 

Yes Chris.
It's just a matter of 10 spline to 6 spline driveshaft.

The industry makes adapters , so you use them both ways around ;-)

 

Thats is what i said.....

 

Yup

 

Yup again

 

35-36 side bell bearings are quite expensive.....
I get them from HRW .
