Quoted from Galooch:So while giving my game a cleaning I noticed small white flakes on my flippers. My only guess is that the left ramp diverter is just barely clipping the bottom edge of the ramp causing some plastic to flake off. I looked but I saw no obvious way to slightly tweak the angle to prevent it from touching the ramp. In case it matters, my diverter is not slamming into the playfield as mine was all set from the factory.
All parts seem to be tight and secure. Anyone else have a similar issue?
Thanks!
From a JJP service bulletin: Maybe #4 will help you.
2. If you Diverter Assembly is still intact. Remove the 2, 6-32 cap screws (#16) using the 7/64” Allen Wrench. If your Jam Plate has fallen off, look on the bottom of the cabinet for the Jam Plate (#12), Cap Screw (#16), Lock Washer (#14) and Washer (#13)
See fig. 1.
3. Re-assemble the Ramp diverter by following Fig. 1. Place (#16) Cap Screw through Lock Washer (#14) followed by Washer (#13),
put the Cap Screw with Washers in either hole on Jam Plate (#12) and using the Allen Wrench screw the Jam Plate into Guide Bracket (#17), repeat steps for the other hole.
4. Test the Diverter by pulling plunger (#15) down until it makes contact with the coil stop. IF the diverter Guide (#4) touched or rubbed against the Ramp, you will need to loosen slightly the 2 Cap Screws and adjust the Jam Plate so that the Diverter Guide does not touch or rub the Ramp during the full movement of the plunger stroke, re-tighten once you are satisfied with the
position of the Diverter Guide.
5. Test your work by playing no fewer than 10 games.
