    New Owner Old Unit

    Very close to picking up a CK that I have acquired recently, its a bit of an oldie (12) and needs a bit of TLC, new loop hoses, new DS4's, cells and batteries, but hasn't had a hard life.

    Does anyone know what length breathing hoses I should order please? Not sure I have the hang of the picture posting but hopefully this works:

    Your unit looks identical to mine ( no.23 ).
    Assuming that , like mine, it has been sitting around for a long time, save yopurself some trouble in the long run and strip, inspect, clean and understand every single component on it. Displays, CMF, ADV , the lot !

    I think mine deteriorated more sitting in a box for many years than, it would have by being used !!!!!

    Yeah will be doing, full set of new O-rings going in too for sure, the only bit I am a little apprehensive about dismantling though is the ADV based on horror stories I have read.

    Do you have the Sherwood reg too, how does it breathe?

    Also do the current mushroom valve diaphragms fit units this old?

    Are you on the gen 1 MAV, did you get the replacement spring that was provided FOC, I haven't been able to check it yet.

    Re: New Owner Old Unit

    To honest, I am not much farther ahead than you with my unit. I bought it nearly a year ago and still realy not used it in anger, many trials in the pool and a couple of trials in duck pond type open water , so I am probably not the best person to give advice , however -

    My ADV has been troublsome to say the least, and after many attempts at setting it up , the best I got was it being exeptionally sensitive or at worst it created a positive pressure loop. I have machined some more 'top hats' for the bottom of the stem, just a fraction smaller in diameter and with the rim slightly lower on the diaphragm plate ( as the origional just catches the centre screw head ) but havent tried them out yet .

    Yes I have the sherwood reg , but as yet, I am not in a position to comment

    Mushroom valves, I dont know if they are the same ( interestingly, mine are in good nic yet I would have expected these to be one the first items to deteriorate )

    I had no idea there was an issue with the spring untill now , but if becomes an issue, I will find a way around it, or swap it with another CMF unit I have

    None of the above has realy answered your questions, but I am sure there will be somebody on here who can......
