I have two Lister CSs to rebuild. They are both models CS 3/1 (one is
3hp at 600rpm, and the other is 3.5hp at 650rpm). I would like to know if it is possible (without too much extra work) to rebuild them as CS 5/1s?Mark
Possible but may prove too expensive. The bore and valves are different sizes. The cylinders and pistons are not that easy to get hold of and I know not whether you could overbore a 3/1 cylinder (I rather doubt it). You'd certainly lose the chroming. Are the pre-combustion chambers also differently sized I wonder? The pump and injector are probably different too. Since the 3/1 is the less common I'm inclined to suggest that it would be better to rebuild as original and sell them to buy a pair of 5/1s Opinions may vary .... hth Roland
