CCKW STARTER TRIVIA

Your CCKW Starter is a direct decendent of the first automobile electric starter designed by Charles Kettering, General Motors engineer, 20 years previously.

Hey, if it works then don't try to improve it.

The Chevy starter is different. No center bearing for one thing.

With 12v makes no difference

But if you compare the SNLs, the Stock Number for Chevrolet 4X4 and CCKW interchange.

According to chev TM10-1557 the chev starter has 12 ft-lbs of torque and the cckw per TM10-1269 has 15 ft-lbs of torque and 525 amps (chev) vs 570 amps (gmc)

That is 25% more torque and 8.5% more amps for the GMC starter

But if you get out of the 1941-1942 TM10 and get into the 45-1951 SNLs that superseeded them, they ended up with the same Federal Stock Numbers. In the real world, when one goes to NAPA, Carquest, Big A, you will get whatever is available. I have three NOS left, one on the CCKW and two on the shelf,and will go see if they are Delco 1107418(GMC), or 1107055, 1107054 (Chevrolet).
Try something for me, go to one of the aftermarket dealers NAPA, Carquest etc, and demand to know if their rebuilt 41-47 Chevrolet/GMC Starters they offer have a torque of 12 or 15 lb/ft.

NOTE:
They are Delco 1107418.

I don't go to NAPA for my starters. I rebuild them myself or have them rebuilt if necessary by one of the few independent starter repair places in the area.

If the later SNL specified the GMC starter for both, that would be one thing, but if they specified either or the Chev, 25% in torque is a BIG diffference especially if you are running 6v at 0 degrees.

That is fine, but what does the average CCKW/Chevrolet owner do? Many of them rely on NAPA, and Carquest, what is your recommendation to them?

Dealers, junkyards, (local) rebuilders, or 12v.

If I am in a junkyard and find a 6v lever action GM starter and I can get it for not too much, I buy it. I do the same thing with GMC 270-302's and Chev 235 - 261's engines

It is good to have a stock of spare parts. I have a NOS starter on my truck at present, or at least it was NOS when I put it on it. I had the old starter re-built at a place in San Antonio for a spare. Spares are great insurance.
