4.3.4 Removing the bearing and end cap 1. Unscrew the flange screws in the bearing and end caps. 2. Pull the bearing and end caps off the cylinder barrel and piston rod. 4.3.5 Replacing the piston components 1. Pull the piston rod out of the cylinder barrel. 2. Inspect the cylinder barrel and piston rod for damage. Note The entire ISO cylinder must be replaced if the cylinder barrel, particularly the bearing surface, shows signs of significant damage. 3. Unscrew the threaded coupling from the piston rod. Note Note the order and alignment when pushing down the piston components. Recommendation: Place the piston components in such a way that correct assembly is ensured. 4.
Push the piston components off the piston rod. 5. Clean the thread of the piston rod and threaded coupling to remove screw locking agent. Illustrated: Multi-part piston 6. Replace the components contained in the set of wearing parts. 7. Push the piston components onto the piston rod, in the correct order and alignment. 8. Wet the threaded coupling with screw locking agent. 9. Screw the threaded coupling onto the piston rod and tighten with the appropriate torque. 28 / 56 Festo 7DSBCb_en Size Tightening torque DSBC-32 10 Nm DSBC-40 20 Nm DSBC-50 30 Nm DSBC-63 40 Nm DSBC-80 60 Nm DSBC-100 60 Nm DSBC-125 170 Nm
