General Cylinder Removal
Instructions
1. Remove any attachment from the machine. Park the
machine on a firm, level surface, allowing sufficient
workspace. Level the machine, place the transmission
control lever in (N) NEUTRAL, engage the park brake,
shut the engine OFF and block the wheels.
2. Place a Do Not Operate Tag on both the ignition key
switch and the steering wheel, stating that the
machine should not be operated.
3. Open the engine cover. Allow the system fluids to
cool.
4. Relieve any trapped pressure in the hydraulic
system by using the handle or wrench (located in the
toolbox) and move the double nut on the side of the
actuator module on the valve section back and forth.
5. Label, disconnect and cap hydraulic hoses and
cylinder ports in relation to the cylinder.
6. Attach a suitable sling to an appropriate lifting device
to the cylinder. Make sure the device used can
actually support the cylinder.
7. Remove the lock bolt and/or any retaining clips
securing the cylinder pins. Remove the cylinder pins.
8. Remove the cylinder.
9. Wipe up any hydraulic fluid spillage in, on, near or
around the machine.
