Removal and refitting the motor

Removal and refitting the motor

Remove the wiper arms and the electrical connections to the motor. Dismantling is a straightforward operation providing that as all items are removed so they are inspected and a note made of their locations. However, reassembly requires more care and the following procedure should be adopted.

1. Mount the wiper unit onto the body by fully tightening the nuts fixing the pivots onto which the arms are fitted. Ensure that the rubber sealing bushes between the pivots and body are correctly assembled to prevent water ingress. Slightly lubricate with glycerine.
2. Secure the mounting bracket lower edge to the body by means of the special square bracket. It is important not to distort the mounting bracket and ease of assembly is ensured by elongated holes in the square bracket. By suitable adjustment the linkages will not be subjected to distortion or abnormal stresses during operation.
3. Fit the motor unit to the mounting bracket tightening the screws and reassemble the main link to the pivot lever. Ensure that the locking of the fastener on the pivot lever is secure so that it does not become loose during operation.
4. Remake all the electrical connections and run the motor for a short time whilst checking all the switch positions including the automatic parking. It is at this position that the wiper blades and arms are assembled to the wiper mechanism.
5. Onto the pivots, install the shims, snap ring, wiper arm, plain washer and lockwasher. Fully tighten the nuts with the wiper arms in the parked position.

6. Ensure that the wiper arms can be tilted 100 deg. downwards without striking against the cowl or front compartment lid. Also ensure that the blade pressure on the glass is 10.6 to 12.3 oz.
