Pump Cam

Separating the cam assembly from the pump rotor housing is a critical process.
Familiarize yourself with the following steps before beginning the disassembly. This
process will require plastic spacing shims to center the rotor in the stator. The spacers
should be 0.03 inch thick. Without these, the rotor will be pulled to the stator once it is
removed from the motor shaft. The rare-earth magnets used in the motor are extremely
strong and will make it difficult to re-center for reassembly.
1. Remove the chassis and separate the chassis. See "Chassis" on page 5-11.
2. Remove the eight outer screws () and lock washers () which secure the upper-
3. Remove the lock washers which are located between the upper-shaft mount plate ()
4. Place the booster pump assembly on a support block with the bottom side facing up.
5. Remove the 1/8 inch compression tube fitting and the retaining "C-clip".
6. Insert the plastic spacers in the small gap between the black stator and the polished

Put the booster pump assembly () on a flat work surface.
Connect the control panel assembly () to the booster pump assembly () as
follows:
a. Install the motor cable retaining clamp (not shown) on the bottom of the
booster pump assembly ().
b. Connect the motor wires from the motor controller inside the control panel
assembly ().
Reconnect the upper pressure coupling () and lower pressure coupling () that
connects the pressure supply lines to the booster pump assembly ().
Reconnect the control panel assembly () to the booster pump assembly ().
Install the eight 7/16 inch nuts (items  and ) and lock washers (items  and )
secures the booster pump assembly () to the control panel assembly ().
Install the four screws () and the four lock washers () that secures the upper
pressure line () to the control panel assembly ().
Use the handles and carefully lower the chassis () into the case.
Tighten the eight control panel assembly screws ().

four inner screws () and lock washers () which secure the plate to the cam
assembly () as shown in Figure 5-5.
and the booster pump assembly housing ().
The support block should only support the cam assembly and not the pump housing.
