Realignment of motor coupler
Realignment of the motor coupler is necessary whenever the motor
and cam shaft have been disassembled.
The spacing/alignment measurements below are also shown on the
diagram on the opposite page.
• A 0.002 inch spacing is required between the hub coupler
(attached to the cam shaft) and the interface coupler which is
located between the motor sprocket and the hub coupler. You
may need to reposition the hub coupler in order to achieve this
spacing.
• A 0.125 inch gap must be maintained between the coupler gear
and the mounting plate.
Reverse the pump assembly removal procedure to reassemble the
pump. Reconnect all cables and the connectors and secure the SPI
cable with cable clamps on the left hand side of the pump housing.
Reassemble the front and rear housings. Before replacing the screws
in the housing, perform the Functional and Accuracy Tests (see Page
7-7). If the tests are satisfactory, complete the Housing reassembly.
