The Fordson Tractor Pages Forum

I’ve found an industrial Ford motor out of a log skidder and the price is right –its free. I was wondering if they are more than 220 cubic inches or more horsepower than a stock new performance Major? If so, I was thinking of putting it in mine, as we have a had a lot of snow this year and could always use a few extra horsepower. The serial number on the engine is S438620. Here's some picture of it and my new performance Major.

That engine has 220 cubic inches, like your NPSM. It could be governed to a different RPM, which would change the horsepower a little. Did it come out of a Tree Farmer skidder? You may be able to find the specs for that model and see how many horsepower it had. I would probably just keep it as a spare.
I've never blown snow without a cab. Does that heat houser keep you very warm?

Lovely tractor. How does it get on with the snow blower? Is it an attachment that needs a lot of power to drive it?

Those engines were comon in some combines over here.
They used to have 68 hp with the same cubic inches as the Majors.

JC, the heat houser does do a pretty good job. Just the windshield alone is nice to duck out of the wind.

Adrian, It does take a lot of power if the snow is wet and heavy. Sometimes more than what the old girl has, so that's why I am looking for a bit more.

I've been told that the industrial motors have a different camshaft and injector pump and that's where the extra power comes from. Also, will an industrial motor bolt into the tractor? The bell housing looks the same as a major motor, and I realize I'll have to put the tractor oil pan on. What does a stock New Performance Major actually make for horsepower. I have heard everything from 48-65hp. Thanks.

Extra power comes from reading it at different revs, the tractor was rated at 1800 rpm the truck at 2100 rpm. There were differences in the pump to allow higher revs.

Basically it is the same engine, you would need to change the oil pump pick-up which will be to the front of the sump on the industrial engine. The front plate will need changing and also the timing cover. The side plate with the breather should be changed too along with the valve cover but other than these items the engine will slot straight in.

New Performance Super should be 54.5 hp.

One of the things that could give problems with your snow blower is the Supers gear ratios which could be a bit fast, so increasing the revs to increase hp might not be an option.

Thought it worth a comment given how few industrial engines are visible on here in pics. This one is a late December 64 one, and the revs will probably be at 2250 rpm. The main differences with a contemporary tractor engine are the sump (528E-6675B instead of E1ADDN-6675B), front mounting plate (591E-6030B instead of E1ADDN-6030A), camshaft (528E-6250D instead of E1ADDN-6250D), rockers (E1ADDN-6468L instead of E1ADDN-6468F and E1ADDN-6469L instead of E1ADDN-6469F), push rods (510E-6488 instead of E1ADN-6488A), rocker cover (592E-6449 instead of E1ADDN-6449D), tappet cover (591E-6519 instead of E1ADKN-6520B), intake manifold (530E-9425B instead of 954E-9425C), timing cover (E1ADKN-6019B instead of E1ADDN-6019), delivery valves (510E-993227 instead of E1ADDN-993227B), injector nozzles (NL179 white instead of NL123 green), governor spring (E720-CL-5 white instead of E719-CL-9 blue) and intake valves (510E-6507B and E97-CP-5 instead of E1ADDN-6507). This pump is one with an exhauster drive, so has camshaft 530E-993201B instead of E1ADDN-993201D, but your lift pump isn't on the pump (the usual E1ADDN-9350 instead of the exhauster 510E-9350 type), it has cover E713-CL-5 instead of E712-CL-9 and requires an extra bracket (don't know the part number yet) in place of the exhauster 530E-2A451 or compressor 510E-2875. The cambox is E711-CL-5 instead of E709-CL-9. It has throttle shaft E762-CL-5 instead of E717-CL-9, with arm E766-CL-5 and assist spring E765-CL-5. You seem to be missing a fan, E1ADDN-8607B will do fine. You might also have crank pulley 500E-6312B instead of E1ADKN-6312C but can't see. You'll need to replace the pipes with E1ADDN-9337C, E1ADDN-993174D, E1ADDN-993175D, E1ADDN-993176D, E1ADDN-993177D.
