Replacing the flipper plunger and link
Steps
- Remove the Allen bolt holding the plunger/link to the pawl (spread the pawl slightly with a screwdriver if needed).
- Fit a new plunger/link rather than rebuilding the old one.
- If you must rebuild: grind the mushroomed tip, drive out the roll pin with a 1/8 in punch, fit a new link and drive the pin back, checking the link moves freely.
- Refit with a new link spacer bushing; the bolt passes through the pawl with its nut on the pawl side.
