I am working on a couple of Harley Davidson pins that while in good overall shape I suspect have seen a fair number of plays. These games have 2 sets of 500-5799-04 4 drop target assemblies. These seem to be the same used back to at least The Adventures of Rocky and Bullwinkle and Friends. On all 4 assemblies, the target lift/reset bracket (535-6509-04) hangs straight down when the playfield is in the normal horizontal playing position and as a result, the plungers for the coils fall out into the cabinet. The stop flange on the lift bracket skips/hops right over the adjustment bracket (535-6508-00).
I think what is going on is because there has been so much use that the holes in the end plates (535-6162-00) where the pivot shaft (530-5180-04) goes through have worn to be much larger and oblong (see the attached picture). Even the pivot shaft itself has worn down to be smaller where it makes contact with the End Plate (see attached picture).
My natural instinct would be to replace the pivot 4x Pivot Shafts and 8x end plates however I can't find Pivot Shafts in stock anywhere. I can get the End Plates at Marco for $16 each but the Pivot Shafts are not in stock anywhere I can find in the USA. It looks like the end plates have the same hole. The end plates have a mirror unused hole to where the pivot shaft goes, it looks like I could get away with reversing the end plates so that the pivot shaft goes through the unused hole but that would not solve the damaged shaft issue. Another option might is maybe I could find a bushing of some sort and drill out the damaged pivot shaft hole and put that in?
Any advice as to what people have done to solve this would be really helpful, thank you!
