Matco Cross Drive Magneto Question

Post by Kenny Edmondson » Fri Sep 05, 2025 8:11 am

I got lucky this week a purchased this Matco magneto. The mag is hot and should clean up nicely. All the gears are there and appear in good shape. One thing I noticed that I thought was innovative is it’s set up for T engines with or without generator provisions.
The only thing that’s missing is the drive coupler. Looks like that will be easy to make. Just curious if anyone had a picture of the coupler so I can make it as close to original as possible? Thanks

Haven’t seen an output shaft with a hex drive before. Typically these MATCO drives have a 1” diameter cylindrical output shaft, and a matching hub to mount to the mag. A short piece of fiber reinforced rubber hose is used to couple. A 1/4” screw and nut anchors the hose at the output shaft side, and a special MATCO bronze hose clamp provides an infinite adjustability at the mag. I have drawings for the output shaft and bushing, can dig em up if you want

Same casting as my Eisemann front mount, including the provisions for use on both style engines.

Kevin, the pictures I found online all had the hose type couplers, but none with the hex. I assumed this mag may be a later model since this mag has the impulse feature for better starting. But that’s only an assumption.
