I have a new (NOS as far as I know) speedometer, and a NOS speedometer cable courtesy of Pete Debella. The Speedometer works, but it's reading way off. When I'm doing 35-40 it says I am doing 60. I've had the speedometer miss read on past jeep that I had a lift on, but I have no lift on this one. Anybody have any suggestions? _________________ 1952 M38A1

Mine does that, but that's because its a NEKAF and so is measuring Kilometers per hour, (64Kph = 40 Mph)
Just a thought! _________________ Andy

The old one I had said "Miles per hour" on it. The new one does not, which I have been told is more correct. It only goes up to 60. With the overdrive, I've hit 60 miles an hour, and the speedometer needle is way past the 60 mark on the gauge. Like if the 60 is due east, the needle is all the way down at due south. _________________ 1952 M38A1

That is an origianl AC speedo. The AC part number is right below the odometer. What make and part number are shown on your speedo? _________________ Wes K

Call Debella,send it back,and get another one.
An original has Miles Per Hour on it.
I have some originals that I turned back to zero,polished the faces,and painted the bezels for $50 if interested.

Debella sold me the cable, not the gauge. Do the gauges you have look and work good? Not all beat up? If so I'm interested. Shoot me an email with details! Dan@danhenk.com
Oh, and Wes, I'm in Austria until late Tuesday, but I'll post when I know _________________ 1952 M38A1

For reference, there's a photo of both the AC unit (I think all Willys M38's & M38A1's came from the factory with those), and the later Stewart Warner unit at the top of this post:

So John, from Midwest Military, says the speedometer isn't the problem. Anyone have any ideas what is? _________________ 1952 M38A1

He says the pinion gear in the military transfer cases was different that the pinion gear in the civilian ones, and that is a likely cause. I had Novak rebuild and send me a transfer case. It has the correct military speedo keyed speedometer cable input, but the gearing might be wrong. I shot an email to Novak to try and find out. They have a great rep, but they don't work on many military jeeps. They sold me an overdrive too that was a mess, after it was popped on and off multiple times, I finally sent it back to them and bought one from Herm. That one worked immediately. _________________ 1952 M38A1
