Platform Level Cylinder
DISASSEMBLY
DISASSEMBLY OF THE CYLINDER SHOULD BE PERFORMED
ON A CLEAN WORK SURFACE IN A DIRT FREE WORK AREA.
1.
Connect a suitable auxiliary hydraulic power source to
the cylinder port block fitting.
DO NOT FULLY EXTEND CYLINDER TO THE END OF STROKE.
RETRACT CYLINDER SLIGHTLY TO AVOID TRAPPING PRES-
SURE.
2.
Operate the hydraulic power source and extend the cyl-
inder. Shut down and disconnect the power source.
Adequately support the cylinder rod, if applicable.
3.
Remove the cylinder length sensor from the cylinder.
See Section 5.4, Cylinder Length Sensor.
4.
Remove the counterbalance valves from the cylinder
port block. Discard o-rings.
5.
Place the cylinder barrel into a suitable holding fixture.
6.
Remove the self-tapping screw from cylinder barrel.
7.
Using a spanner wrench, unscrew the cylinder head
from the barrel.
8.
Attach a suitable pulling device to the cylinder rod end.
EXTREME CARE SHOULD BE TAKEN WHEN REMOVING THE
CYLINDER ROD, HEAD, AND PISTON. AVOID PULLING THE
ROD OFF-CENTER, WHICH COULD CAUSE DAMAGE TO THE
PISTON AND CYLINDER BARREL SURFACES.
9.
With the barrel clamped securely, carefully withdraw the
complete rod assembly from the cylinder barrel.
