Fordson major with Gasoline/Petrol engine

Postby dromonedog » Wed Dec 05, 2018 5:12 pm

Does anyone know what the differences are between the Fordson major Diesel engine to the gas engine other than the head. Are the pistons, liners etc different and gasket sets

I've never seen in a petrol or paraffin major engine but pistons probably different as the diesels have the usual combustion crown, the parts drawings / listings for all E1A variants are on line somewhere, fordson.se probably, have a look at the different listings and see which part numbers vary is probably your safest bet.

The cylinder head is completely different as it has the combustion chambers cast into the head. The pistons are completely different as they have a flat top, they are a smaller diameter than the diesel and the cylinder liners are thicker with the same outside diameter as the diesel but a smaller internal diameter. The camshaft is different. The inlet manifold is different as it mounts the carburettor. For a petrol/TVO engine the exhaust manifold is different as it incorporates a vaporiser. The distributor is fitted in place of the injection pump. The cylinder head gasket is thicker. The thermostat has different opening temperatures. The fan is different to give a greater cooling capacity with 4 blades and bigger diameter. Other than this most other components are the same on diesel, petrol/TVO and straight petrol engines.

Hi,

Cylinder liners for petrol/parrafin are same as diesel, for pure petrol they indeed have a smaller bore. Head of parafin engine is also different to the petrol head. If i remember correctly, valves and rocker are the same for diesel and petrol, but not for vaporising engine.

Petrol paraffin engine have been made upto the MKII engine, petrol to (nearly) end of production, according to parts list.

Parts like conrod, block casting, crankshaft are interchangeable.

Thanks for your comments, wondering where one could buy liner kits, gasket sets, rod and main bearings

Virtually all of the straight petrol tractors were exported to the USA and Canada, so I would expect that if there is any chance of finding original liners and pistons for these engines it will be from somewhere in the USA or Canada. Failing that you can have liners and pistons made to the original pattern - there are companies in Great Britain who can manufacture any size of liner and there are others who can manufacture pistons and rings, however the cost is likely to be substantial.

You might get away with the thickest type diesel head gasket, or possibly make one out of copper sheet. There are firms in GB that can make up head gaskets for obsolete stationary engines, whether they could make up a gasket for an engine this size I do not know. Con rod and crank main bearings will be the same as the diesel engine.

I'm fascinated by the petrol (gasoline) version of the Major.
Why was it produced? Why did Ford feel the need to create this version?
I believe Brian in one of the posts on this great website mentioned that the (now defunct) GPO ordered a fleet of the petrol version.
Hope to see much more info on this subject. A 3.6 litre petrol engine in a great tractor sounds like a flight of fancy, and I love the idea!
Best, Adrian.
ps Bet it sounds great. Wonder how it labours under the strain of ploughing.

I don't know how big the US / Canadian market was reckoned to be Adrian but petrol / gasoline was dirt cheap in the US until more recent times, not sure how it compared to diesel at that time but certainly not carrying the sort of tax burden it had in the UK. I'm more surprised that petrol paraffin models were considered viable, perhaps as diesel had not by then gained much of a foothold in UK agriculture - the TVO tax 'rebate' here ended around that time, praps Ford didn't see that coming ? either way it was a modern, innovative tractor and at that time standardisation of parts was not so common as it has become, you can't fault UK Ford for that aspect.
