Early B Manual Start Conversion?

Postby GusJ » Sun Apr 03, 2022 9:34 pm

I have an early model B with only a manual start. The block is cracked and needs replaced. I was wondering how easy it would be to buy a block with the starter mount. Also what would it take to set up the starter, I believe I would need a generator. Would also plan on switching to 12v if possible. Very new to this but set on getting the tractor running and improved a little. Thanks

The starter goes in from the back side of the flywheel. So you need a bell housing with the starter opening. Your flywheel may not have a ring gear, and may not be notched for a ring gear. If you want to put on a generator (or alternator) you may find the fan hub doesn't have the pulley for the generator belt. Of course, you will need a battery box, a bunch of wiring, and maybe a voltage regulator,

By the way, you can find the installation instructions for the starting attachment in the PDF manuals on this site. Select "PDF Manuals" from the "Quick links" at the top left of this page. Select the [Farmall A, Super A, AV, 100, 130 and 140] and [Attachment Manuals] folders. The manual is "Farmall A & B Special Attachments - lighting".
