4. Remove the poppet assemblies (12). See Poppet
Repair, page 22.
5. See F
IG. 9. Remove the outer valve cover (47).
6. For motors with DataTrak or the linear sensor:
a. DataTrak Models: Remove the two screws
(135). Carefully remove the DataTrak module
(131), see page 12. Disconnect the runaway
solenoid and sensor cables from the module
board. Remove the two screws (134) and care-
fully slide the housing (132) off the air valve.
b. Linear Sensor Models: Remove the screws
(134) and carefully slide the housing (132) off
the air valve. Disconnect the sensor cable from
the circuit board. See F
IG. 14 on page 23.
7. Remove the four muffler screws (43) and the four
screws (41). Remove the air valve (40). Inspect the
gaskets (46).
8. To repair the air valve, go to Disassemble the Air
Valve, page 18. To install a complete new air valve,
continue with step 9.
9. Lubricate the gaskets (46) and ensure they align
with the holes at the back of the air valve (40). Install
the air valve. Thread the muffler screws (43) in by
hand. Install the screws (41) and torque to 15 ft-lb
(20.3 N•m). Torque the muffler screws (43) to
120-135 in-lb (13.6-15.2 N•m).
10. For motors with DataTrak or the linear sensor:
a. DataTrak Models: Carefully slide the housing
(132) onto the air valve. Thread the screws
(134) in by hand, then torque to 40 in-lb (4.5
N•m). Reattach the solenoid and sensor cables
to the DataTrak module (131), see page 12.
Carefully slide the module back into the housing
(132). Reinstall the two screws (135).
b. Linear Sensor Models: Reconnect the sensor
cable to the circuit board. See F
IG. 14, page 23.
Carefully slide the housing (132) onto the air
valve. Thread the screws (134) in by hand, then
torque to 40 in-lb (4.5 N•m).
11. Install the poppet assemblies (12). See Poppet
Repair, page 22.
12. Reinstall the top cover (30).
13. Reconnect the air line to the motor.
