Product Description
Here is a sharp looking early American Bosch MJA4A104 magneto. It is a clockwise rotation device with a 40 degree timing lag and a 20 degree adjustable range. The timing lever also serves as a grounding (stop) switch. The impulse coupler drive cup tangs are 15/64 thick. These were used on the early Allis Chalmers 50 and 75 and the Case A12-20, K18-32, P, Q, and T25-45 per the American bosch service literature. Check your tractor parts manual to be sure. It has been completely disassembled, bearings washed and repacked with a modern sunthetic grease,points polished and set, magnet charged, condenser and coil tested well within serviceable limits and has a new gasket. It was bench tested and is good and hot as it should be. Will ship to US addresses. If any questions please ask. Thank you for looking!
