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 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 (MOTOR OR ENGINE
CANNOT BE STARTED).
3. To service the piston cup seals (40)
approximately 2 feet of clearance is
required between the front of the
pump fluid cylinder (37) and any
obstructions. If there is insufficient
clearance, the pump must be
removed and relocated to an area
where adequate clearance exists.
4. To access the piston cup seals (40),
the cylinder cover clamps (57) must
be removed (except as noted for
L0918 in service tips above and some
L06 models). Remove six of the nuts
(61) holding the cylinder cover clamps
(57) in place, and then remove the
cylinder covers (54). Do not remove
the two nuts (61) on the opposite
corners of the fluid cylinder, as they
keep the cylinders (39) and fluid
cylinder mounted on the pump during
this operation.
5. Some pumps may be equipped with a
single cover plate that secures all
three cylinder covers. For these
models, all eight nuts (61) must be
removed to facilitate removal of the
cylinder covers (54). For some L06
models with no cylinder covers, the
fluid cylinder (37) must be removed to
access the pistons.
