Here is a sharp looking rebuilt heavy duty replacement Fairbanks Morse FMK4A11 4 cylinder magneto made for early International Harvester applications according to the magneto factory service manual. It is base mounted and turns clockwise. It was a heavy duty design for the Waukesha engine used on an early International combine. It will also work in other IHC tractor installations requiring base mount clockwise rotation and a 35 degree impulse lag.Tractors used the lighter duty FMJ4A11. This is one of the biggest and baddest Fairbanks Morse magnetos ever made. Check your parts book to be sure. It has been completely disassembled, washed, blasted,primed,painted, bearings relubed, contacts serviced,magnet charged,new gaskets and impulse serviced. It has a new coil, condenser and was professionally bench tested good and hot as it should be. Good and hot and looks great.Would also make a great spare. Any questions, please ask! Thanks for looking! Will ship postpaid to US addresses,payment due in 5 days, may return in condition sent in 10 business days for refund if not pleased.
