Strange that it only has the one added pin/screw. I would think the top plate would have either just one, or two at 180º apart, or three at every 120º. I'd have expected the original (Call it 0º), the added one at 120º, then one at the existing hole at 240º.

My Dancing Lady has three pins on the top disc of the score motor cog, the third pin is taller than the two other and operates one switch on the 'E' position, switch stack '3". Obviously a dancing lady is no the same but multi player Gottliebs can have a lot of switches around the score motor. There is a picture on the IPDB website of the interior of a bunyan but its too small to make out how many pins it should have.

The E level switch stacks require a longer pin than the D level switch stacks. The Paul Bunyan schematic shows that one of the three pins above the top cam should be longer to activate the E level switches:

The longer E level pin is a way to randomize features in the game since it will only activate E level switch stacks every third time the motor runs on average. This game should have E level switch stacks in positions #1 and #4, each with a single make/break (1C) switch.

I think any upper score motor cam with a longer E level pin will work, or you could add one to the empty hole at about 5 o'clock in your photo.

The Score Motor cams and pins are all symmetric; they all repeat three times around the cams. If you were to slice the motor into three equal pieces the pieces would all be the same. The optional E level pin is the exception - it is taller than the other two pins but in the same relative position.

The smaller empty hole to the left of the gap in the top cam in your photo is symmetric with the other pin I can see. The larger hole doesn't seem to have any others in the same relative position.

And those two next to each other don't seem right either.

Magnified photo from IPDB, a bit hard to see, but on the left side of the disc are the two pins and none others that I can find. Nobody that owns the machine has sent in a photo? That would make things much easier!

Here’s a picture of the score motor from my project Paul Bunyan. Let me know if you need anything else.

I have not replaced the 'triggers' on my score motor, but I cannot guarantee they are original.

My game resets and can play full games but has scoring issues, primarily with the ABC rollovers and targets. To my knowledge, the hole value lights function correctly - they alternate and each hole lights periodically for four times value.

Here are photos of my score motor at rest at position 1, followed by position 4.

Hope this helps!

Wow, this has been an education. After seeing the photos of two different Paul Bunyon Score Motors contradict some of the things I wrote earlier in the topic I needed to understand why. All of the Score Motors I remember working on are symmetric apart from the optional extra long E level pin. This one is clearly not. It has two pins side by side in one of the three sections and no pins in the other two sections. What's up with that?

The Score Motor drawings on the schematic (in replies #5 and #7) don't reflect the extra short pin but looking in the parts catalog there it is:

Also not shown in the schematic or parts catalog are the D level pins missing entirely from two of the three sections. Ok, so it's a thing. But how is it used on Paul Bunyon?

I couldn't understand from the schematic how the kick out holes could score 6 different values: 50, 100, 150, or 4x those values: 200, 400 or 600. The trick is the unusual configuration of the Score Motor D and E level pins.

The first clue was the 600 point hole value. 600 points can't normally be scored with a single 1/3 rotation of the score motor (until later in the 70s anyway with some of the elaborate bonus scoring games) because usually the Motor 1A switch is used to generate multiple scoring pulses and there are only 5 Motor 1A pulses per cycle:

After watching a few videos I realized that it doesn't all happen in a single 1/3 turn of the Score Motor.

Essentially what happens is that any time the ball lands in one of the holes the game awards either 50 or 200 (4x) points right off the bat. But depending on where the twin D and E level pins are the ball might not be kicked out after 1/3 motor turn because the hole kickers are driven by the 3D pin which only comes around once every 3 motor cycles. If it takes 2 motor cycles for the 3D pin to reach the hole kicker switch the hole value is awarded a 2nd time for a total of 100 or 400 points (or double). If it takes 3 motor cycles for the 3D pin to reach the hole kicker switch the hole is worth a total of 150 or 600 points (or triple).

The hole value lights know where the pins are and how many cycles it will take before the ball is kicked out so they light up the appropriate hole value based on the position of the two pins. That's also why the hole values change every time the score motor runs - because the pins are in a different position

Glad you found a solution!

Yes, the ABC sequence carries over from player to player and across games until completed.

I remember reading your thread about this and will keep it in mind when I tackle my project.

I always learn something from your posts!
Thank you for sharing your knowledge.

Be careful because this circuit runs on 120 volts
