3 Disconnect the Hall Sensor (8) at the in-line connector (21).
4 Remove the cable ties that secure the Actuator side Hall Sensor wiring to
the Sensor Mounting Bracket (22).
5 Remove all P clips (3) securing the Hall sensor wiring to the Sensor
Mounting Bracket.
6 Loosen the two cap screws (1) and (6) that secure the Hall Sensor (8) to
the Sensor Mounting Bracket.
7 Move the Hall Sensor to de-tension the Timing Belt.
8 Remove the Timing Belt from the two Timing Pulleys (12) and (not
shown).
9 Remove the M10 Sensor Mounting Bracket attaching screw (23).
10 Remove the two M5 Sensor Mounting Bracket attaching screws (9).
11 Remove the Sensor Mounting Bracket from the Actuator.
12 Loosen the cap screw (13) and remove the Hall Sensor Pulley from the
shaft.
13 Remove the two cap screws (1) and (6) and two washers (2) and (7) to
release the Hall Sensor from the Sensor Mounting Bracket. Note that the
cap screw towards the centre of the actuator also has a stiffnut and

Fit Sensor Mounting Bracket
Note
When reassembling, all screws should be fitted using Loctite 2400 thread
locking adhesive or equivalent.
1 Ensure the Timing Belt is positioned over the Position Indicator Shaft.
2 Position the Sensor Mounting Bracket in the Actuator and secure it with
the M10 cap screw (23) and two M5 cap screws (9).
3 Using the hand wheel, turn the actuator to mid position.
4 Ensure that the cap screw on the Position Indicator Shaft Pulley is
accessible to aid realignment of the Sensors.
5 Locate the Hall Sensor (8) onto the Sensor Mounting Bracket.
Note
The cap screw (6) towards the centre of the Actuator attaching the Hall
Sensor to the Sensor Mounting Bracket has a further spring washer and stiff
