  2. Secure clutch pedal so that it remains in normal position (at the engaged limit stop). To do this:

    Secure clutch power spring using a cotter pin (approx. 3.2 x 20 mm) or place a suitable object under the clutch pedal so that (when the push rod is disconnected from the clutch master cylinder) it does not shoot forward (towards the disengaged limit stop) unintentionally/uncontrollably (danger of injury).

    Another option (in addition to the securing methods mentioned above) is to guide the pedal towards the disengaged limit stop with your hand (pedal fully depressed) immediately after the clutch master cylinder is removed.
