I have an early fordson major the timing gear (62 tooth is broken) and so is the crank shaft where it is bolted to the gear
would love to obtain these items but sadly am no able to find them so will sell for wrecking photo is available it has new tyres all round
There are a few on ebay at the moment. I don’t know if I'd pay what they are asking unless they guarantied to give a full refund if the unit is bad, just because "the engine ran when we took it off" doesn’t mean the pump is any good.
And there are basically three different pumps, early 7mm, the 7.5mm (most common) and the Minimec mechanical governor. You can search, Simms, Minimec, and Fordson.
