Centralize bush in spring eye and fit a fibre washer AHA6370 to each side of the spring.

These washers were fitted on initial assembly from MG Midget Car No 7442 and Sprite Car No.12068.

Interleaf Friction

Fit interleaf pads AHA6428 to each spring as described below:

1. Remove rear spring (Section H6 of Workshop manual) and dismantle leaves.

3. Centre-punch a central point ¾” (19.05) from the end of fifth leaf “C” as shown.

4. Drill leaves where centre-punch 7/16” (11.11mm).
