Perform the procedure below to replace the entire pump
lower with a new or different pump lower.
1. Follow the
on page 15,
and unplug the power cable.
2. Disconnect the material hose from the pump outlet
and remove the hopper.
3. Remove the outlet manifold assembly from the
pump lower.
4. Remove the bottom tool-less clamp and inlet check
valve assembly from the pump lower.
5. Push up the retaining spring (5a) and push out the
pump pin (5b). The pump pin can be pushed out
towards the back side of the pump towards the
motor and hopper for easier disassembly.
6. Remove the top tool-less clamp while securely
supporting the pump lower housing. Once the clamp
is removed, the pump lower will drop.
NOTICE
The pump lower must be supported during removal.
Failure to do so may cause the pump to drop and
damage may occur.
