I have been asked some advice by a mechanic from another company who doesn't have huge experience on hydros . He has just inherited a 5 stop Inground that was originally otis but has recently been partially modded with a smartrise controller . He did the annual tests with the inspector and when he tried running up onto the stop ring he hit the ceiling before the ring . I told him I have never Personaly done it but I believe the answer is to sleeve the piston and advised him EECO or similar could machine the sleeves for him but the issue is with it being in ground how does he know what length of sleeve to use ? He could be 1 inch off hitting the stop ring or 3 feet , how would he know ?
All I could think of was to measure how far he is overtravelling to hit the ceiling deduct six inches from that and that's the length for the initial sleeve , then also have a number of two inch sleeves made to add if required .
I'm guessing someone else on here must have come across this situation ? Am I missing a trick ?
