I have .240mm nozzle, I built another pump with a 12mm and the same came plate (extra aggressive and much lift), and that make 2 times when I exceed the 4200RPM the hub pulley slips on the pump main shaft :cry: the timing falls out of ranges and the engine stop.

I am unable to run this pump over 4000rpm, probably that I should put larger nozzle, or put in a less aggressive came plate, less power too

pulled apart a 12mm ve pump today....noticed that it had four piece cam plate rollers including the pin and washer....do all ve pumps have this construction on the rollers ....for some reason I remember them being only two piece construction.... :?

Hi Tin Tin....I would assume that you run the four piece roller in your 12mm pumps?.....it seems this roller design could handle much more pressure.....anyway I'm going for the 12mm pump head (I found two of them at the scrap yard).....my pump base is a peugeot pump 1.9 going on a 1.9 ALH.....I may just stick the head on and see what happens.... :shock:
