'47 Pickup/Open Drive Banjo pinion torque spec?
 

I am planning on replacing the pinion seal on my open drive banjo tomorrow, and I would like to get the torque spec on that nut if anyone has it! Any help would be greatly appreciated!

Thanks...

I took her apart & put her back together. It'd be nice if someone out there could give me the piece of mind I'm looking for so I'm not scared to make those 140mph passes!!! :eek: Ok... so maybe it won't go that fast... but I'd still like to know how Ford recommended replacing that so I can drive her around town with piece of mind!

The U-joint flange does not control the bearing pre-load on that model so it is safe to use a torque spec consistent with the diameter and thread type.

In that wonderful banjo overhaul thread on the Hamb, it was stated the ideal situation is to clamp the pinion shaft in a vice, grab the banjo with both hands, and spin it. According to the writer, it should go no more than one rotation. I tried with my open drive banjo, and the thing spun about five times! :D:eek:

With fhe open drive banjo is easy to get a pinion bearing preload torque reading by using the retaining nut with an inch-pound wrench.

The "spline-only" banjo needs a special tool which connects to the serations or a tool made from a coupler.

Thanks for the input!

Bassman... I was doing this work under the car with the rear axle in place. I tried to spin my banjo, but just couldn't quite muster up the strength! :D

It sounds like I may have torque'd it accordingly. It's different than most rear axles I've done since it's a castellated nut & cotter pin.
