Hi all,

Can someone please show me a photo or describe to me, how the steering column attaches to the steering box on a 1941 Chevy passenger car ?

I can see the outer column tube is slipped on over the steering box input shaft and is clamped in place.

I want to know how does the inner shaft which is attached to the steering wheel and the worm in the box, how is that shaft attached to the input shaft on the box ? is the input shaft one long shaft where one end is the steering wheel end and the other is the worm ?

Or can it be separated like newer cars can with the rag joint ?

This drawing from the Chevrolet parts catalog shows the parts you asked about and should answer your questions about the construction of the steering box and shaft.

As you can see, the steering shaft is one continuous piece from the steering wheel to the worm. What the drawing does not show is that there is no seal at the upper end of the steering box. If you cut off the mast jacket (the outer tube) above the box, this will allow airborne particles to get inside the box and cause damage to the internal parts.

We might be able to give you more helpful answers if you could explain in detail the reason for your proposed modification to the shaft and mast jacket. If this is related to your plan to add power steering, then you might want to look at the link to Unisteer I posted in your other thread.


Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

Thanks Ray !

The steering box and pitman arm on my car are different in detail to the one in the diagram. My 41 Chevy has a 2 piece pitman arm and the steering box mounting bolts are in a different position.

However I do see that the worm shaft is one unit upto the steering wheel.

The reason I asked is, to see if the steering column could be separated from the box so that I can use the same column with a power steering box.

I will further elaborate in my other post about improvements.
