Telescope Cylinder (E450A only)
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 PRESSURE.
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 counterbalance valve and fittings from the cyl-
inder port block. Remove wear pads from the cylinder.
4.
Place the cylinder barrel into a suitable holding fixture.
5.
Mark cylinder head and barrel with a center punch for
easy realignment. Unscrew the cylinder cap from the
barrel.
6.
Attach a suitable pulling device to the cylinder rod end.
EXTREME CARE SHOULD BE TAKEN WHEN REMOVING THE C YLINDER ROD,
HEAD, AND PISTON. AVOID PULLING THE ROD OFF-CENTER, WHICH COULD
CAUSE DAMAGE TO THE PISTON AND CYLINDER BARREL SURFACES.
7.
With the barrel clamped securely, apply pressure to the
rod pulling device and carefully withdraw the complete
rod assembly from the cylinder barrel.
