Bosch 3 gear mag drive

Making room for bigger and better toys! Been saving this mag drive for parts as it has new idler and driven gears installed. Magneto mount is clearly homemade, but appears to be correct enough to function properly. Cover has the typical fan belt damage and welding. Housing has the typical grinding clearance from someone trying to make the wrong timing cover work. Could be patched up and ran as is, or scavenged for parts.

Designed to run on an early non generator engine with late’12 thru early ‘13 timing cover with small oil spout. Can also be used on all generator type engines with the ‘19 generator delete side cover installed. There was also a special Bosch timing cover with small oil spout and no timer register.

As pictured, $150 + shipping


I have extra mags, but only cores. I have patterns to make the special timing covers, but no finished covers available. I may have a ‘19 side cover, but would need to find it. All available at extra cost
