Traction Speed Sensor Replacement - Toro Reelmaster 5500-D Service Manual

Traction Speed Sensor Replacement

Removal
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch.
2. Jack up the front end of the machine about 1 ft. (30
cm) to prevent transmission fluid from leaking from the
gear box when the sensor is removed (see Jacking In-
structions in Chapter 1 - Safety).
3. Disconnect electrical connector from the harness.
IMPORTANT: The position of the sensor within the
gear box is very critical for proper operation. When
removing the sensor, do not change the position of
the jam nut. A new sensor must be replace to same
position as the old sensor (Fig. 51).
4. Remove lock nut, sensor and O-ring from the ma-
chine screw and gear cover. Inspect O-ring for damage.
Installation
1. Lubricate O-ring and bore of the mounting plate with
grease. Install O-ring into groove of the mounting plate.
2. Install sensor opening in gear plate so the machine
screw goes through the hole in the sensor ear.
IMPORTANT: Do not change the position of the jam
nut when tightening the lock nut to the machine
screw.
3. Secure sensor to the machine screw with lock nut.
4. If the position of the jam nut is changed,
A. Run jam nut down the machine screw until it con-
tacts the mounting plate.
B. Insert sensor into hole in cover so hole in sensor
goes over the long machine screw.
C. Make sure sensor contacts the axle gear.
D. Thread jam nut out until it contacts the sensor.
E. turn jam nut one more complete turn to pull the
sensor out from the gear.
F. Secure sensor to the machine screw with lock
nut.
5. Lower the machine to the ground.
