Anyone know where to find a ring and pinion set for my 47 pickup? I want a 3:54 or higher to replace the 4:11 there now. I have a set for a 41, will they work?

They will work. Swap meets and want ads. 3.54 sets are hard to find.

Rather than buy a used set (which won't be cheap) consider a new set. But, before buying talk to someone who has used Speedway. Remember in the old days when it was "Getz Gears"?

I just looked at the Speedway link posted by 19fordy, and was surprised to find that their ring/pinion is specified for 35-48 cars, but ends with 41 pickups. Are 42-47 half ton banjos any different than passenger car banjos?

exoilfld · 09-29-2013, 02:02 PM

That is what I was wondering. I know the 41 is a closed driveshaft and the 47 is open. If they will work, I am set. Don't want a used set.

Now I thought the engine and complete driveline was changed together for the '48 model. I hadn't known the torque tube ended in 41 for the pickup.

The pick-up pinion ('42-'48) will need to take a U-joint yoke, unlike a torque tube-type slip joint. DD

exoilfld · 09-29-2013, 03:11 PM

So, are you saying the pinion will not work? If not, I am back to a set from somewhere.

exoilfld · 09-29-2013, 03:13 PM

Not sure when the tube ended. I just know I have a 41 with a tube and a 47 with an open shaft.

Rowdy · 09-29-2013, 03:43 PM

42-47 pickups are open drive shafts. Rod

As you know, ANY '41 is torque tube. The '47 pick-up is "open" drive, with a "normal-type" automotive driveshaft with U-joints on each end. The PINION shafts are vastly different between the two at the driveshaft-attachment ends. DD

Check these two links of MacVP's to see the pinion differences. DD

There is a kit (pricey) to convert a close drive rearend to open drive...now if the parts will physically install into your '47 rearend, you may get by with minimal work needed, since you have the majority of the "kit" in your '47 rear...

It might be possible to just use/find the correct Yoke for the splined earlier pinion shaft.

Speedway sells the kit...on know on the HAMB many have converted without the kit, machining what was needed for a seal retainer and using "some" easy to find Yoke.

Edit:

Here's the Speedway kit..
