Rotate the wear adjustment screws (part M) approximately one-eighth turn
The solenoid gap should be 7/16 inch when in proper adjustment.
Maximum torque may be obtained after operating the brake several times and then
rotating either wear adjustment screw very slightly either way and noting which position of fine adjustment provides
satisfactory stopping without changing the solenoid gap.
(a) After the housing has been removed, remove the 3 screws (part A) holding the
support plate assembly (part B) to the endplate (part C) and lift the support plate assembly from the endplate.
Remove the stationary ring (part D) and lining (part E).
Reassemble with new lining.
(d) With the coil deenergized, rotate both wear adjustment screws
counterclockwise until the brake lining is free to rotate or until the solenoid gap is not increased by further rotation of the
wear adjustment screws.
(e) Rotate one wear adjustment screw clockwise until the solenoid plunger moves
downward slightly. Repeat utilizing the other wear adjustment screws. The initial movement of the plunger occurs when
the wear adjustment screw contacts the stationary ring (part D).
REPLACEMENT OF SOLENOID COIL
1. Disconnect the solenoid from circuit.
Insert a screwdriver between the support plate (part K) and the lever arm (part L).
Wedge apart and remove the bearing and pin (part N) and solenoid lever (part M) with the
solenoid link and plunger.
Remove the coil clamp screw and washer (part P), coil clamp (part Q), and coil holder and
plunger guides (part R).
Remove old coil and insert new coil. Reassemble and connect leads.
