RH Helical Drive for 50 MT Starter

You need a RH helical drive (when facing drive end) either 11 or 12 tooth but the sources for the drive appear to have dried up.

The 42MT positorque (or Spragg?) drive gear can be replaced with a new gear - G2751PT was available last year from VanBergen and Greener in Illinois 800-621-3889 for $21.35.

This was in 2015??? Post #29 Thread 3J D2 Direct Start Question

You need a RH helical drive (when facing drive end) either 11 or 12 tooth but the sources for the drive appear to have dried up. You are exactly right Old Magnet, the sources for the drive appear to have dried up. At least now I have another number to try. Thanks

restore49 I will call these folks tomorrow and see what is available. (2015???) If I can get the gear, Maybe I can turn the straight gear off the drive I have and weld the new gear on this drive. If not, it may be time to set the mill up and make an 11 or 12 tooth RH helical gear. This may get real interesting before it gets over. Thanks Brian Boaz

Helped me out with Starter nose and Helix.
Good to deal with even from the land down under.

Bboaz:
The gear itself is replaceable - comes off your Positorque Bendix. No machining required.
