Heisler Overdrive Install

[jdwalkbehind]

I'm getting ready to install a heisler overdrive into a 37 unstyled A. Anyone who has done one (or a behlen) have any pointers on the best way to install it? Any way to get it installed without pulling the differential/rear end? Any advice is appreciated.

Thanks

Not sure about a 37A or Heister but I installed a Behlen overdrive in my 35B last summer. Had to remove the flywheel, cover on flywheel side over the
transmission shafts, top transmission cover, clutch pulley, and first reduction cover and gear. Basically I had to replace the 2 existing shafts with longer
ones so that gears 5 and 6 could be added on the flywheel side. I didnt have to do anything with the final drive or from the rear of the tractor. Took lots
of pics with my phone through the process to aid in putting back together. Im certainly no expert after 1 install but am happy to answer any questions if
I can. Feel free to email me. Good luck!
