    Hi guys,

    Probably one for MfAndy or some other knowledgable chap on here.

    Our 575 (dual clutch) just has the lift pump and no aux pump (usually denoted by the short pipe looping the flow and return together beneath your left buttock LOL).

    Query to start off is, when overhauling the lift pump (full overhaul kit) is it a do-able job to fit an aux pump while the lift cover is off, assuming I could find one or more likely just buy a new one. If so, what bits apart from the actual pump would be needed. ie Are there gears, shafts, brackets etc required in there along with buying a pump.

    Looking at options for increased flow for spools and loader etc without faffing about with the selector valve always. Overhaul kit is just to treat the old girl to some renewed lift performance, she deserves it after 42 years

    Also, am I the only 500 series owner who got fed up of the linkage for said selector valve and just machined a control knob that just came straight out from the selector

    Thanks in advance

    Gerard

    you will need a plated drive. this is a housing and gears that transfers the drive up to the aux pump, a suction pipe and outlet pipe, a different side cover for the suction and outlet pie to fix to. a breaker could help with the non wearing parts.

    I'll try a couple of the yards I know, not the end of world either way but would be an addition all the same.

    Also, which pump do I need to look out for (visually) if I spot some at a yard. I think some have two ports on top and others have three........or something like that

    Some have 2 suction holes some have one. You could get away with either. You will only use the main outlet port. The other 2 can be left open and will just circulate oil.
