  • pbl shock

    How do you 'check' the shock absorber on PBL (aside from no movement of it)? and is there an adjustment?

    The shock should be mounted on the even lane side of the pair of lanes....there should be a couple spacers and / or a jam nut with the shock extended most of the should move very little on most PBL installs.

      I am rebuilding a ball lift in the shop for a problem pair we have and want to eliminate as many sources of trouble as i can since this will be the 2nd time trying to correct this prob. Is there a way to check it before i install?

        to check a shockie you should be able to get resistance when pulling the shaft out and then pushing it back in. inside the shockie is a set of valves which allow the oil to travel between compartments at a set rate. if the valves fail they will oil all the oil to travel thru without any blocking. the main action of the shockie on a lift is in the up movement to keep some pressure between the belt and ball. on a pbl shockie there should be 1 inch of packing between the flange at the top of the slide section and the rubber grommet plate. the nut tightening the grommets should be tight.
