Ah, no, i didn't. Unfortunately my mother-in-law knocked over the box of carefully ordered parts and they got mixed up. Due to the super-fine operating tolerances and the parts already having worn in the piston assemblies had to be assembled as they came out, having mixed up the parts meant that i was trying to rebuild the assemblies with the wrong parts. Despite trying what felt like scores of permutations i couldn't get all three to work smoothly at once, so i sacked it off as a bad job and chalked it up to experience. There were also a couple of springs and shims that fell out of the pump housing when i removed the central cam shaft and struggled like hell to replace - about three hours work for my Dad and I, my dad used to be a hydraulic pump engineer, so you'd expect him to be more help than your average bear - and i'm still not sure we got them back in right.
I'll try most things and will always encourage people to try it themselves if i think it's doable, but i think this is something best left to a specialist with the equipment and information available to do it properly. Having since further researched the subject i'm also aware of exactly how fine the tolerances are, how you need a huge variety of shims and springs available to make necessary, tiny adjustments, and how much the specialists rely on their testing equipment and manufacturer specifications to make repairs, without which it is simply not possible to do the job properly.
That said, please prove me wrong, i'd love to know how to get around the inevitable cost factor.
