131 MODELS -LATE PRODUCTION

GENERAL INFORMATION:

Attached are diagrams showing the cable winding sequence

for both right and left doors of the X1/9 and 124 Spider.

Also included are the instructions for the replacement and adjustment of these window regulators.

In addition to the above information, a list of modifications to the front window regulator system on late production 131 -4 door models has been enclosed. These modifications allow for easier operation and service adjustment.

This information should be made readily available to all service personnel.

124 SPIDER WINDOW REGULATOR INSTALLATION –ADJUSTMENT

The attached diagrams show the window regulator cable winding sequence for the right and left door of the 124 Spider.

Follow instructions below for window regulator installation:

1. DO NOT remove the metal clip securing the cable tight against the drum until the cable has been strung on all the pulleys.

2. Attach the window regulator to the door panel and start the cable on the top front pulley then following the diagram over, each pulley in turn. String the cable on the adjustable pulley last. (To make this procedure easier it might be necessary to loosen the support bar for the lower two pulleys in order to provide more slack in the cable).

3. Tighten lower pulley support (if loose).

4. Slightly tension adjustable pulley and remove the metal clip.

5. Working with the adjustable pulley, tighten the cable until all slack is removed.

6. Lubricate the cable and pulleys with light grease.

7. Attach the window to the cable checking to see that it has full travel in both directions.

8. Check for free operation of both window and regulator.

NOTE:

Window regulators are interchangeable for either door.

XI/9 WINDOW REGULATOR INSTALLATION -ADJUSTMENT

The attached diagrams show the window regulator cable winding sequence for the right and left door of the XI/9.

Follow instructions below for window regulator installation.

1. DO NOT remove the metal clip securing the cable tight against the drum until the cable has been strung on all the pulleys.

2. Attach the window regulator to the door panel and start the cable on the top front pulley then following the diagram over each pulley in turn. String the cable on the adjustable pulley last.

3. Slightly tension adjustable pulley and remove the metal clip.

4. Working with the adjustable pulley, tighten the cable until all slack is removed.

5. Lubricate the cable and pulley with light grease.

6. Attach the window to the cable checking to see that it has full travel in both directions.

7. Check for free operation of both window and regulator.

NOTE:

Window regulators are not interchangeable.

131 -4 DOOR MODELS FRONT WINDOW GLASS MODIFICATION

For better understanding, the number before each description refers to the corresponding number on the attached drawing. The modifications to this system are as follows:

1. The lower front window channel bracket, which secures the channel to the door, has been strengthened by increasing the thickness from 1 mm. (approx. 1/32") to 1.5 mm (approx. 1/16").

2. The upper slotted snap type bracket on the front window channel has been redesigned and thickened from l mm. (approx. 1/32") to 2mm.(approx. 5/64") for increased reinforcement.

3. The diameter of the holes for the window regulator adjustment has been increased in size to permit added adjustment positioning.

4. The support bracket of the glass has been redesigned to increase flexibility thus compensating for the movement of the glass.

5. The glass support has been increased in length and a guide has been added on the front side of the support. This modification insures proper travel of the glass.

6. The clip, which secured the rubber weatherstripping inside the rear window channel has been eliminated. This eliminates possible interference between the weatherstripping and the glass.

7. The positioning of the upper bracket on the rear window channel has been modified for alignment purposes.

The new window supports listed in point 5 are the only part numbers which have been changed (new part #4367698 right side and 4367699 left side). All other parts involved in these modifications retain the existing part numbers.
