Farmall H Live hydrolics

[James Bates]

I would like convert my H to live hydro. Will the pump off the 300 or 350 fit? Do I have other options?

To answer directly, maybe, and sort of...

The IH live hydraulic pumps are the same for the Super H, 300, and 350 gas. You can still get these new from various sources.

"Maybe" the pump would fit depending on how old your H is. Some time in 1950, the front engine cover and the timing gears were changed to fit the IH live hydraulic pump. The vast majority of Hs were built before 1950, though, so it's not likely yours is new enough. The front engine cover and timing gears would have to be swapped out from ones out of a 1951 (just to be safe) or newer H in order to fit the IH pump.

"Sort of" because M&W manufactured a live pump that fit stock Hs. These can be found used, but generally worn out and unrepairable due to lack of parts availability.

Neither option is cheap. The M&W pumps fetch a pretty penny when they come around on Ebay even though you're likely throwing your money away. IH pumps run $600 or so, and used ones fetch at least half that, but I wouldn't recommend buying a used one due to the risk of ending up with a bad one. Would you rather spend $600 and have a new warranteed pump, or $350, get a bad pump (which can't be rebuilt) and then have to spend another $600 to complete the project?

i have the pump off a 300 on my h depending on the yr of your h you might have to change the front timing cover and possiblly the cam gear.

James, Two of the four bolt holes of the 300-350 pump will match. I drilled and tapped the third and made a simple clamp on the upper left bolt. This was about 40 years ago, it has had many thousand hours use with no problems and I did not change any of the timing gears. Good luck, Chuck

Other options include a belt drive from the crankshaft, or a shaft drive through the front bolster.

As someone else said below, I think you need to change the camshaft drive gear and timing cover to a 300 cover to use a 300 pump.

Only on the old ones. Mid '51 and newer Hs already have the new style cover and gears.
