My first A-C, a model C. The distributor is mounted vertical but I have seen them horizonal. Is this an after-market conversion?

TM, lets make sure what you are looking at. The engines with the distributor pointing upward, with the 90 degree angle drive are distributors, that have an external coil, just like an old car. The magneto powered tractors have the "black wire cap" pointing rearward toward the back of the motor (horizontal). The magneto units have an internal coil and do not require a battery for ignition. The early ones were hand crank units. Not sure of the actual dates, but i have a 1948 and 1949 C and they both have distributors which i belive are original. I also have a 1952 B and it has an original magneto. I dont think the B motors got distributors till very very late in production, if ever, but a lot of C units had them in the late 1940's, as far as i know. After that, all CA units had distributors in the 1950--on.

Steve, Sorry, your Cs have been converted. A-C started using battery ignition in models B, Ca and WD in 1953. Model Cs were out of production as you probably know, in 1950.

A model C with a distributor of any kind has been changed over to battery ignition from its original magneto. Several outlets including Allis dealers sold conversion kits with a vertical distributor. These kits bolted on in place of the magneto with no other changes except wiring. The factory battery ignition setup used a different governor shaft and other parts, but was introduced after the model C was out of production and was used only on late Bs and CAs. The horizontal distributors you have seen are most likely units salvaged from IHC tractors. They bolt right on and are the only horizontal distributor I have seen that will fit.

Thanks Butch, you explained it. So my upright is an A-C aftermarket type to replace the original mag.

I have a CA with the old mag on yet and it has been nothing but trouble. (Finding someone to work on it that knows how is the biggest problem) What year and model IHC will fit on it. I had never heard that before. There is not many CA's around here. Thanks Harold

The ditributor and drive from an H,M, W-4, W-6, the supers and probably other models will bolt right on in place of a mag on any Allis with a flange mount mag and RH rotation. The vertical mount distributor kits that were once sold by the car load at places like Central Tractor fit many models of A-C, IHC, Oliver, MM,etc etc all with one part number. The flange mounting and right hand rotation were pretty mutch industry standard.
