Farmall 350 utility engine for farmall H

WayneT · Jun 24, 2014

Does anyone know off hand what would be required to put a Farmall 300-350 Utility engine in a Farmall H? The biggest differences I see from pictures is the front engine mount/cover and manifold.

Thanks...

Yes the front cover needs changed, some bolt sizes are different in block but it can be and has been done with bolt hole drilling of front cover or block thread inserts.
Governor lever and a few other easy changes needed also. Use the row crop front pulley to keep timing marks right.

Installing 300 or 350 engine in H

This is for a rowcrop 300 or 350, haven't done a 300U engine.

To install 300 or 350 engine in a H
1. If you are planning on using the 300/350 live pump be sure to use the timing cover and related parts for 300 or 350, SH or late H (older H bolt holes are different).
2. Use the H fan, 300/350 fan is to large in diameter.
3. Use the air cleaner & pipe from air cleaner to carburetor for a SH, the one for an H is to small for the 300/350 carburetor.
4. Use a 300/350 or SH flywheel and a SH clutch plate and pressure plate if you are going to pull it hard (H flywheel, clutch plate and pressure plate will work but is smaller, H 10”, SH/300/350 10 ½” ).
5. Use H governor or use throttle shaft from H governor in 300/350 governor.
6. Have to convert vent from back of head on H to vent from valve cover for 300/350.
7. Change oil pressure fitting from H onto 300/350 block before installing side rail channels (fitting is hard to change after rails are installed).300/350 had small line from block to gauge.
