Motor Installation
1. Place the motor on the motor plate and align it with
the marking indicating the location of the previous
motor.
2. Use a 1/2 in. socket to fasten bolts (22) and secure
the motor to the motor plate. Use screws (37) to
install motor cover (5). Make sure cables are routed
out the back and the reed switch connector is
routed as shown.
3. Place the motor plate on the frame (1) and partially
hand thread all bolts (22). Once all bolts are started
and the motor plate is aligned, tighten bolts (22).
4. Use a 1/2 in. socket to install the B-side gear
housing with bolts (107) and torque to 200 in-lb
(22.5 N•m).
NOTE: Install both gear housing cranks in the
bottom dead-center positions. This will make sure
that both pumps change over at the same time.
5. Use a 5/16 in. hex key to install the B-side pump
housing with bolts (110) and torque to 25-30 in-lb
(2.8-3.4 N•m). Use a 7/8 in. wrench to connect the
fluid line (13) to the pump.
6. Repeat steps 3 and 4 on the A-side pump.
7. Install the reed switch on the B-side gear housing.
8. Place the outlet manifold on the motor bracket and
use a 3/16 in. hex key to secure bolts (60).
Reconnect the A-side pressure transducer cable to
the A-side pressure transducer. Reconnect the
B-side pressure transducer cable to the B-side
pressure transducer. Reconnect the heated hose
and recirculation lines.
9. Route the motor cables to the electrical enclosure
(2) and connect to MCM ports #9, #14, and #15 as
indicated by labels on the corresponding cables.
See Electrical Schematics on page 69.
10. Slide the bottom pass-through plate to secure the
opening and tighten.
