1940 Ford coupe had the steering box rebuilt over one year ago. I noticed that the castle nut on the shaft coming out of the box to the steering arm (I believe that the shaft is called a roller shaft) has no cotter pin. There is also no slot seen in this shaft to accommodate a pin. The nut is very tight but I am concerned. Any thoughts and input would be appreciated. Bill

Many steering boxes, particularly the pre-'46, didn't have a cotter pin lock, but used a lock washer, instead. The shaft and Pittman arm are splined, so the tightness just serves to hold the arm in place.

There should be a large cotter pin there. I would get under the car with a good light and a big wrench and search for the hole. I have a 1940 also and it has the cotter pin.

Thank you for the quick reply I will double check to see that either there is a hole for a cotter pin or at least a good lock washer.

Authentic 1940 shafts used BOTH a lock washer and a cotter pin. When the steering gear was replaced, perhaps the shaft was replaced with a non-OEM part? Hope this helps. Mike Kubarth

For what it is worth, when I checked the "green book", it shows steering boxes with the lockwasher only in some of the views. It can be difficult to see a cotter pin hole, as they are often filled with grease, etc. That is why we lightly score the ends of the rear axles with a file to show where the cotter hole is as we cinch down the nut.
