H Sleeve question

johndeeregreen · Mar 23, 2012

I was told Farmall switched sleeve sizes once during the production run. The serial number is FBH-319969X1 if they did switch sizes, what size do I have?
Thanks!

The answer is we cannot tel you. The history of the
H is the only way to tell without measuring.
All H tractors were: Bore/Stroke:3.375x4.25 inches
[86 x 108 mm Displacement:152.1 ci [2.5 L]
The Super H was: Bore/Stroke:3.50x4.25 inches [89 x
108 mm] Displacement: 164 ci [2.7 L]
Thin sleeves can be put in an H to increase its
displacement to that of an SH. Thus yours could be
either. Jim

If you are overhauling the engine, don't order parts until you have pulled head and measured the diameter. That is the only way to know.

Jim think you would want corrected on the information. Thinwall sleeves in a H gives a piston bore of 3.4375.
