Rollergames diverter replacement

So the diverter was a bit of an issue.  It had built up some pitting and would not close the gate the entire way.  This meant the ball would get stuck along the top area.  Well, sometimes it would rattle a bit and roll down, sometimes the machine would need a shove.
Either way, this classic game by Steve "king of flow" Ritchie was not flowing at all.

Note the pitting in the bar, dug in by the solenoid slamming the roll pin against it

These diverter bars were considered Unobtainium, but amazingly someone on pinside had reproduced them.  (they apparently still have a few available, so best stock up!)
And the guy that owned the game had already got his copy:


 Only problem is, once it was installed the gates STILL were not closing all of the way!  What's up with that?

Turns out, this diverter bar is the SECOND take on the diverter mechanism.

First version, from the manual:

Second version, via a tech bulletin:

A crucial difference is that the revised version used a special coil stop that was a bit shorter than the normal one.  Part code subcode B, or something like that, and it was no longer around to order.
Luckily it is far easier to subtract than add, so I took to grinding it!  Not on an electric grinder, nope that'd be too easy, I got it in my head to just use the tools I had and grind it by hand.
Not recommended.
(edit: it is Solenoid Bracket Assembly B-13488 revision 'A')

Another look at the diverters:

This is not properly closed...
If the coil stop is too long, the solenoid can't pull in the entire way, and you don't get the proper curve

This smashed corner is an example of the damage that can happen when the diverter is not hitting the correct spot.

And last but not least, I want to mention how annoying games are when the playfield just has a pivot point.  No sliding it up + forward, and therefore no easy access to disassemble the back end of the playfield apparatus.

So what to do?  First, struggle like hell to lift the playfield up off the pivot brackets.  Then get a board and slide the playfield forward, resting the flipper solenoid brackets on to it.  Thanks to the pinsiders for the tips on this.


It should never have come to this.

And Rollergames is gone as well, now!  Back home to it's owner with many a problems solved.
Oh, what to do with all of this sudden space????
