6. Preload servo spring as follows:
-
Use an appropriate spring tensioning tool, e.g. brake spring pincers by Hazet (Hazet No. 797), to preload the servo spring until an auxiliary
tool (steel pin with 8 mm diameter) can be inserted into the bore of the rocker from the side.
-
To protect the mounting block, use a liner when applying the pincers.
