Perform the procedure below to replace the
entire pump lower with a new or different
pump lower. Before following the pump
lower replacement procedure, perform the
Pressure Relief Procedure, page 24 and disconnect
the material hose.
1. Remove outlet fittings (OF) from the pump lower
outlet.
2. Loosen the hopper elbow clamps (V), retract the
spring-loaded locking pin (Z), and slowly swing
the pump up until the spring loaded locking pin
clicks into place.
3. Remove the hopper elbow (26) from the pump
lower (908).
4. Lift up the pump spring guard (906) and
disconnect the hydraulic displacement rod by
removing clip (916) and disassembling the
coupler cover (917) and assembly coupling (918).
5. Unthread all three lock nuts (907) from the tie rods
and remove the pump lower (908). The pump
lower should now be separated from all other
parts. Replace the pump lower and reinstall it into
the unit. If the pump components need replacing,
see
Replace Pump Components, page 30 .
NOTICE NOTICE NOTICE
The pump lower (908) is heavy. Dropping the
pump can cause damage to the equipment. Make
sure you have a secure hold on the pump lower
when removing the last lock nut (907).

jam nut (806) when the top surface of the mounting
cylinder plate (809) is flush to /- .060 in. of
the top surface of the outlet housing (805). The 1–1/2
NPT hole in the outlet housing (805) should be in line
with the flats on the mounting cylinder plate (809).
