Steering columns and horns

[dr deuce]

I was looking in the last WW2 parts manual that included the M27 and was searching on steering parts to trade to someone.

I accidently discovered that the steering column had the position of the contact brush for the horn changed from or to ~14" to ~38" sometime during production, though no sn's were mentioned.

I will have to check all my CCKWs and spare column assy's and Chevys.

Reading the parts manuals in the cold winter is "interesting" and "informative"....

sorry that my reply is questions, not answers, but I have been
thinking about the steering box for a while now.

Am I correct in assuming that the Wormshaft is fully integral with the inner steering column, which is hollow and threaded to recieve the
steering wheel?

If this is the case, with the age of the unit, possible ingress of
moisture over the years, and metalurgical factors such as hydrogen
embrittlement, then the only way to be sure would be to strip the box
and examine this component very carefully, even x-ray!

The next part of the equation is then spares, are they available?

Any information on the repair/replacement/substitution would be of great
interest to me, as I have not seen any discussion of this before.

It is at least hollow down to the slip ring for the horn contact.

Keeping the unit lubed and adjusted should prevent any problems. The later units are pretty rugged. The biggest problems I have seen leading to failure are water going down the column to the box. I lost my Chevy bomb truck box shortly after I got it home. Wheel just went round and round...
