Fordson super major

1. FMD 1951-56 40hp
2. FMD 1957-58 48hp
3. FPM 1958-60 52hp

After this it gets confsuing. There are three Super Majors.

1. FSM 1961-62 (Simms Pnuematic Governer) 52hp or 54hp
2. FSM 1962-63 (Simms Minimec injector pump) 54hp or 60hp
3. New Performance FSM 1963-64(5000 in the US) 54hp or 60hp. This engine has a modified cylinder head iddentified by the letters "FL" cast between injectors 1 and 2 and they also changed the injector nozils. This change, acording to the truck service letters, was to reduce exhaust emmissions by improving the swirll. I do not know if this increased the HP.

I have a video (New Holland) that states, "FPM hp was increased from 48 of the FMD to 52, and the introduction of the FSM saw a further increase to 54hp". This is why think the Minimec pump may have increased the HP to 60. I have also cross refrenced the truck and tractor parts books and after 1962 it appears that injector pumps and camshafts became common at that point.

Note that the truck version of this engine produced after 1957 (intoduction of a revised cylinder head,larger bores in the injector pump and a new camshaft) was 62bhp at 2400rpm. The tractors rev at 1800rpm.

Hope this helps. If anyone can add to this and confirm through quoting official Ford printed matter from the 50s and 60s (service letters etc) I would be most appreaciative.

Thanks

Diesel = 40.5 Petrol = 39.5 TVO (kerosene) 38.5

1954 to 1958 no. 1425097 to 1481090

Diesel = 44

1958 to 1964 no 1481091 to 1599501, 1599502 onwards: Diesel = 51.8
All HP quoted are at 1600rpm and are bare engine.

Ford Motor Company data 1963.

Thanks. I have seen those figures quoted before. I have also seen offical FoMoCo documents (not mine, belongs to a collector in Albury NSW) that quotes the FSM as 53.9hp. The engine did change in specs from the FPM to the late 62FSM. Not only the injection systems, but the camshafts and cylinder head ports. I think the correct figures are,
1. FPM and 61/62FSM 51.8(52)
2. FSM Minimec pump, 53.9 (54)

The 60hp claim is a verbal from a New Holland dealer. Can't be verified, but I can't see why Ford would bother adopting a new fuel injection system for a tractor and truck engine that would not give any benefit when they knew there was only going to be two more years production. Also, I still give the 60hp claim some merit as a 2hp increase is not realy worth while persuing either, I just want more evidence. The engine was extensivly modified when the "D" Series trucks replaced the Thames Trader range and the engine was not used in tractors with the introduction of the world range. Like I said in my post above, it is confusing and there seems to me to be a lot of contradictory evidence.

Why was Ford so coy about the HP figure on these tractors? I have parts lists, service leters and operators manuals for all of these tractors as well as the trucks. The truck hp figures are easily available but not the tractors.

BTW, the 330CID six cylinder is rated at 100hp in trucks and 86hp as the marine/industrial version. The four cylinder truck petrol (gasolene) is rated at 72 and the six at 115, both at 3200RPM. The petrols only have a 95mm bore. We are toying with bulding a 330 CID six cyl petrol /gas engine using TVO pistons and sleaves and puting it in a early E1A Major for the tractor pulls ( I have a number of Thame Trader Trucks, petrol and diesel 7.5 tonners in my collection). Any coments from anyone?
