H Transmission Gear Mystery

Hoosierfarmall · Jul 2, 2011

I bought a 1947 H for parts, but it ran too good so I have yet another project... fourth gear didnt work, I assumed I would pull the lid off and find the 4th sliding gear with no teeth... what I found was a smaller 36 tooth gear, with all of it's teeth, that lacked a good quarter of an inch from engaging onto the lower 4th gear on the counter shaft?? I got a good 4th/5th of ebay, installed it today and everything works perfect. The 36T removed is stamped T136G, incidentally, the inner teeth went onto the main drive gear perfectly, and it fit the main shaft perfectly. Anyone have any ideas what it is and why it would be there? My parts book doesnt list a 36T for any specialty application for an H or for an M.

No guess of why, but it looks like the 300/350 Utilities used a 36 tooth gear.

In the '60s Tractor Supply Company sold a kit with a high speed forth gear. It contained new gears for second, third, and fourth. Second was speed became what third was before. Third gear equaled the old fourth speed and a new fourth speed was between the old forth and fifth.

My dad installed the kit into his '43 H. It ruined the tractor as a tillage tractor because of the loss of the old second gear speed. He ended leaving the loader on it all the time. Field work with it became mostly cutting and raking hay. It was a good tractor for hauling the loads of bales because of the faster fourth gear.
