MP.8 - WIPER MECHANISM
The windscreen wiper mechanism comprises a uni-directional motor with an external rotary link, a con-
necting rod, and a pair of actuating links which join the connecting rod to the arms of the wiper spindle. This
mechanism provides the wiper with a motion which is slowed at each end of its travel in order to ease the
inertia loads during direction changes, to the benefit of refinement and durability. The motor and wheelbox are
mounted on a single fabricated steel bracket which is bolted to the windscreen scuttle panel.
To remove the wiper mechanism:
1. Remove the front clamshell (see sub-section BP.5).
2. Remove the wiper motor protective cover by releasing the two screws into the windscreen buttress, and
the patch of adhesive between the inboard end and the screen gutter. Disconnect the harness plug from
the motor. Disconnect the washer tubing.
3. Remove the wiper arm from the spindle, and the spindle rubber surround.

4. Release the three screws securing the motor mounting bracket to the windscreen frame - one at each side
of the spindle, one at the motor end, and withdraw the complete mechanism from the car.
5. If the motor is separated from the mechanism, the position of the rotary link should be marked against
the motor shaft for reference when re-fitting. The motor should be in the 'park' position before fitting, and
the mechanism at full travel so that the rotary link and connecting rod are aligned in the fully extended
position.
