My belt changer isn't working correctly in that the air cylinders will not retract. This happens for both the high and low range cylinders. The electrical side of the system is working well. There isnt a problem with the solid state relays, my mac valves work fine. This seems to be some mechanical sticking, maybe on the shaft that holds the two idler pulley cranks. That shaft has a lot of bearings in it that are like washers, the stack is under compression up against those bearings.
At any rate, It seems crazy to me that fadal uses air cylinders that are only one way, with a very weak spring return.
has anyone replaced their air cylinders with a dual action one? (air for both directions)? any idea what size of air cylinder to buy?
This machine does not have the hydraulic system. maybe it should have that instead. anyone else with this trouble with their air cylinders?
