I spent time tonite to poke around to see if I could improve my right orbit shot registration issue (been terrible) -
1. Removed the diverter mod
2. Enlarged the diverter assy mtg holes with a stepper bit and pushed the assy forward ever so slightly.
3. I noticed a bur was forming on the leading edge of the left lane guide - where the diverter arm meets the guide. The ball would BOUNCE when it encountered this transition point in BOTH directions. I removed the bur with a dremel wheel to make perfectly flush with the diverter arm
1. I am getting very consistent fast and smooth left orbit shots. YAY!
2. Better still, I registered all but ONE Mystery/EB shot to the right lane! DOUBLE YAY!
3. I'd call this a pretty good success!
1. I found a chunk of broken plastic up near the diverter arm - maybe 1/4in x 1/4in square, blue color with printing on it. I inspected for a bit but could NOT locate which plastic was broken. Nothing obvious jumped out at me anywhere.
2. As I removed the upper playfield and ramps, then the large plastic sheet, I noticed a nice crack on the leading edge of what would be the cover of the Dragon Kickback lane, about 3/4in long. I added a mylar patch folded over the leading edge near the crack with hopes this would add padding to the leading edge of this large plastic sheet, and also help the crack from propagating. None of this is visible and its tucked under the upper playfield. I think I'll fabricate a sacrificial protector strip from acrylic sheet and mount just under the full leading edge.
3. Nearly every mounting hole in the ramp optos were stripped. I could only just barely get any resistance when tightening the screws. I'll address this next time I get under the hood.
4. Found the rubber bumper for the Dragon coil in the bottom of the cabinet.
5. Titan White sling rubbers were wearing badly on the bottom corner near the flippers - chewed-up and narrowing. I did not have any spares so I simply rotated the rubber to put the wear spots around back, facing the outlanes. Time for another order, I guess.
