Dismantling the retarder
Remove the four screws that hold the
centrifugal unit against the belt pulley.
Release the centrifugal unit from the
belt pulley by pressing the guides down
(black and white arrows).
Use compressed air to clean off dust, as
required. Note that the retarder must not
be lubricated.
Assembly
1. Align the guides of the centrifugal unit
against the belt pulley. Fit the four screws.
2. Turn the brake drum so that its holes
line up with the holes in the belt pulley.
3. Drive the axle down about 1 mm to
get a tight fit between the ball bearing,
washer and belt pulley. See page 48 "Fit
the belt pulley".
Fit the washer.
4. Lock the belt pulley with a mandrel
and fit the washer and centre screw.
Tightening torque: 28–31 lbf·ft/38–42 Nm.
5. Turn the belt pulley so that the brake
drum mounting hole lines up correctly
against the bearing housing. Fit the three
screws.
Assembly of the centrifugal unit
Normally the unit is handled without
dismantling it. If needed, carry out
assembly of the parts in the following
manner:
1. Place the spring in position in the
guide plate. Note where the spring ends
should be located.
2. Locate the brake drum in its position.
3. Assemble the brake shoes by stretching
the spring with a screwdriver and then
locating the brake shoe in position.
4. The complete centrifugal unit.
