•
For high temperature systems—every 6 months of regular use, or as required.
11.2.1
Removing the Cylinder Barrel
NOTE:
This procedure is the same for both ambient and high temperature systems.
1.
Ensure that the piston is fully retracted before removing or installing the cylinder barrel.
This minimizes the side forces on the piston during cylinder barrel removal and
installation. Operate the pump so that the piston is in its Max Retract position before
proceeding.
2.
Remove the Speedbite fittings from the end of the cylinder barrel and tip the cylinder
downward to drain its fluid.
3.
Use the adjustable face spanner wrench to remove the cylinder barrel retaining ring nut.
Refer to Chapter 2, Section 2.2 if needed.
4.
Grasp the cylinder barrel by hand and pull it
straight out
from the cylinder housing. Be
sure to pull it straight out and away from the cylinder housing. Never put any sideways
force on the cylinder barrel because this may break the piston.
If an active wash assembly is used, a firm pull and some twisting back and forth may be
necessary to get the cylinder barrel to move initially. Once the cylinder barrel is released
IMPORTANT
Excessive side loads on the piston during cylinder barrel installation or removal may
break the piston.
