trying to find an actuator cylinder for my kick down jack HWH part number RAP0547. Jack is standard profile AP2007. Cylinder is toast as its developed a hairline crack. any used one out there?

You can get one from any dealer that get one for you they are about $250 just bought one from a hydro lick shop atoo hard to get it right.the new one just fireplaces one in five min,Hope you can find one.no adjustment nessary just watch. For the springs when you a take it off.
Good luck Lenny
