hi guys ,up at my uncles farm hidden away in the corner of the shed i found an old what looks like a fordson major diesel engine which i think has come out of a truck, the no under the manifold is h22d on the other side of the block 1561880 also on the block e1adkn 6015 e the cover on the top is grey has a simms injector pump and starter, was hoping to take out the auxiliary drive shaft and pump gear and fit then into my tvo major just wondering if the gears and shaft are the same , also got the serial no of tvo major 1219492 no under the seat f9t and near clutch pedal b22t .
many thanks wayne

You have a late Power Major engine from September 1960 and an early Fordson Major from March 1952.
You will not be able to change the oil pump but you can change the shaft and gear. You will have to press the pump gear off both and then change them.
When you press the gear onto your pump, you will need to measure 132.08mm to132.13mm from the surface of the pump gear to the under surface of the drive gear, not to the hub of the drive gear, and leave a .010" gap between the drive gear and the top of the pump.

hello brian took the auxiliary drive shaft and pump out of that old engine and the shaft looks right but the gear on top of the pump is different theres no notch on the top for the dustrubtor drive

does this mean that the shaft is different too. also on my major the oil pump seems to be seized i can't turn the pump gear but that other pump is very free running

don't know what would cause the pump to seize .
thanks wayne

That is a bit of a problem as you must use the two together. It should be possible to machine or cut a notch. The problem is that the two parts, gear and auxillary drive shaft must be made of the same material.
Cannot think of a reason for the pump to seize unless someone has had it to pieces and assembled it wrongly, not kept the right clearances. You are going to need that pump as the later one has a different relief valve set up and is not interchangable.

hello brian i took a closer look at that gear on top of the pump and it has e1addn marked on it , does this mean i can't use it as it ment for the diesel engine , the centre bit on top of the gear does not look tall enough to cut a notch in it, i'll try to post a picture or i'll email one , that engine i found could it have found it's way into a truck cos the sump was made out of alloy and had no plate to get at the oil pump pick up screen or mountings for the pivot, the exhaust manifold is different too, next job extract that oil pump from my major, any tips as i'll be on my own and everthing looks heavy and awkward.
many thanks wayne

That gear is certainly not for a distributor drive. All the gears shown in the manuals and parts lists and even on after market replacement parts have the long, notched top.
Yes, everything is heavy. Look at "Henrietta overhaul" on the Wiki. There are pictures on there on how to get the sump and front off. Not easy but I did mine as we always used to and managed it on my own.
