DISASSEMBLY
1. Following removal of cylinder from excavator attachment,
support cylinder on some type of sturdy work platform and
drain all oil. Rotate cylinder so that piping ports are on top,
to allow trapped air to vent.
2. Position piston rod so that it is extended approximately one
half meter (20").
3. Remove bolts (7) on the end of cylinder.
NOTE: Wrap a cloth or other protective material around
piston rod, to avoid possibility of accidentally
scratching or scoring rod surface while
fasteners are being loosened and removed.
Component parts (numbered in parentheses)
are keyed to Figure 4.
CAUTION
Vent air from the hydraulic system before disconnecting
cylinder piping connections. Use the lever on the reservoir,
while the engine is running. Discharge the hydraulic
accumulator and vent residual tank pressure after the
engine is shut off. Pour clean replacement fluid back into
the system if excessive fluid is lost.
