Everything will fit and work. Just be sure to be aware of the "backlash" of the governor gear to the camshaft gear.

I don't see why it wouldn't work. Might be cheaper to buy some kind of digital one from Summit or JCWhitnney. Ground speed would be worthless. Almost is on a D17. Tach is very busy and in a hard to read place. I use it for hours more than anything.

I did the same thing on my Farmall Super H, back in 1969. My local IH dealer's parts man had set aside a
used distributor drive gearbox for himself to put a tach on his H, and got a new tach for a 300/350 and a
drive cable. It's worked faultlessly except the one squared end of the cable rounded off and I installed
a new cable. The speedometer is even pretty close, just a percent or two off due to rear tire size. Oh,
and the hash mark for PTO rpm is 1750 on the tach but is actually 1650 on the SH.

I checked and the WD-45 and D-17 will be about 5% off on the speedo, due to 12-28/13.6x28 tires on the
WD-45 and 14.9x28's on the D-17.

I've got plans to put a tach on my '51 M too, think Steiner's sells the distributor gearbox, and the
tach. Wish we would have done that back in the 1960's when the M was #2 fieldwork tractor, main
chore/loader tractor, and it ran the Knoedler burr mill grinder to grind cattle feed from 8000 to 10,000
bushel of ground ear corn every year.
