10.2 Removing the Fluid Cylinder
NOTE: The fluid cylinder (37) may be removed to inspect for internal damage, to be
repaired, to replace the fluid cylinder, to replace damaged cylinders, cylinder o-rings, or
to service piston rod seals.
Some L06 pumps require fluid cylinder removal to service the pistons.
Refer to Figure 4 for illustration of parts.
1. It is recommended that a sufficient quantity of clean water be pumped through the
fluid end before starting any service procedures that involve fluid end
components. This action will remove a significant portion of contaminants left in
the fluid cylinder by the normal pumpage and improve the ability to work with
parts or see potential problems.
2. Bleed off all pressure inside pump fluid end before starting any service work.
Shut the valve on the inlet piping if provided to prevent flow of liquid from the
source into the pump during service. CAUTION: CHECK TO INSURE THAT
THE POWER IS LOCKED OUT AND TAGGED OUT.
3. Remove the cylinder cover clamps
(57) and cylinder covers (54) as
described in the previous section.
Remove the outside corner fluid
cylinder nuts (61) if they are still in
place.
4. Rock the fluid cylinder (fluid chamber)
to loosen from the cylinders (liners)
(39), and then pull free of the fluid
end studs. If the pistons have
already been removed, take care to
insure that the cylinders (liners) do
not fall off of the front of the power
end and become damaged.
5. To remove the piston assemblies,
refer to the previous section.
6. Inspect all parts for signs of wear or
damage. Replace parts if required.
