Cropmaster and 950 block

[Clarabell]

is a 950 block the same as a cropmaster petrol parafin

I would think not, there would be more bolts holding the head on a 950, there may bo other differences as well.

A 950 cylinder block would be ok but the sleeves are not interchangeable. The pistons in a standard Cropmaster are 3.5’’ diameter. A 950 has 3.5/8’’pistons and an 850 has 3.5’’. Pistons from a Super Cropmaster or 30C would be ok in the 3 5/8 ‘’ sleeves. The front/rear main bearing caps may need a little work with an angle grinder for the block to sit in the frame.
The cylinder head would fit ok. The two extra studs that the 950/850 block has are not required.
There are a few other little alterations.
Check with www.davidbrownparts.com For the availability of 3 1/2 bore sleeves for a 950 block.

Hi i have two Trackmasters that have 950 engines in them,was done before i got them, as i understand it there needs some fitting ajustment around the back bearing cap and seal to the chassis frame to fit. A friend did another trackmaster and that was the part that was made to fit and wheel tractors would be the same good swap if you have a 950 motor or block.
