Linear Style – Bally Flipper –
With Lane Change or Upper Flipper Switch
Bally linear flipper parts
Bally linear flippers. Linear flippers were used by Bally for only a short period of time.

1) Coil stop
2) Diodes
3) Coil
4) Spring
6) EOS switch with
c) lane change or upper flipper switch (not on all models)
7) Crank Assembly
a) Plunger
b) Nylon bushing

Linear flippers were used by Bally for only a short period of time. The nylon bushing wears out quickly.  These flippers can be converted to the earlier flipper mechanisms that are more reliable. Contact your parts supplier for information as to what to order for your pin.

Williams (Not Fliptronics) Prior to ~1992

Williams flippers used in System 11 and on into 1992, are not very different that earlier flippers.  The coils are different (changed from serial to parallel  coils) that are easier on the switches and are different coil numbers.  There is also a capacitor located near the EOS switch.

4) Capacitor (new one comes with a kit) 2.2 uF
15) Coil Stop
17) Flipper Coil
20) Coil plunger spring
21) Crank Assembly
23) Bushing

Williams Fliptronics – EOS switch is open

Note: DE/Sega/Stern is similar.  EOS will be closed.

1) Coil Stop

3) Coil
4) Spring (note its position here)
5) Crank Assembly
6) EOS switch (normally open NO)
7) Bolt holding flipper bat shaft

The diodes as shown in this image should never be left ‘swinging in the breeze’ like in this photo.  They are likely to break.   The diodes should be pulled tight to the coil tabs.

7) Allen bolt to tighten the flipper shaft
8) Shaft to flipper bat

Coil Stops

Coil stops determine how far the flipper opens.  A shorter coil stop will allow the flipper to open more.  A longer coil stop will restrict the flipper opening to a shorter distance.  A long coil stop, resulting in a shorter opening could make it more difficult to ‘cradle’ a pinball in a flipper.

From The Pinball Resource:

A-12390 = 0.420″  Williams/Bally games from 08/1993 to 06/1999
A-12111 = 0.370″  Williams/Bally games from 02/1988 to 04/1993
A-10821 = 0.330″   Games prior to 1988 and after the first generation SS games.**
A-8143, A-7414, A-6492 = 0.3125″ Used on later EM pins and early SS.***  

** From PinballLife: – Used on Laser Cue, Space Shuttle (some machines, but not all), Sorcerer, Comet, High Speed, Grand Lizard, Road Kings, Pinbot, Millionaire, F-14 Tomcat, Fire!, Fire! Champagne Edition, Big Guns, Space Station.

*** From PinballLife – ‘Williams flipper coil stop used from Blast Off (05/67) to Laser Ball (12/79)’

The A-8143 is not typically used on current SS pins as it is too short.

The A-10821 coil stop is the shortest and would result in the largest flipper throw.  The A-12390 is the longest and would have the shortest flipper throw. 

Most games specify a certain coil stop and therefore a throw.  The Addams Family specifies A-12111. Indiana Jones (Williams) calls for a A-12390. 

If trying to retain the original feel of a game, one should always use the specified coil stop (and coil strength).  Otherwise, there is nothing to prevent an owner from putting in a different length coil stop – although one should insure that the flipper does not strike anything in the game, nor make shots more likely to damage playfield parts.

Coil Sleeves

Rebuild kits come with coil sleeves.  If one wants to purchase them separately, for backup, The Pinball Resource has a great coil sleeve guide.  For some reason, their listing of Bally (pre-Williams) is blank.  

Marco provides this information:  Coil Sleeve – 1-3/4 X 1/2 inch. Nylon coil sleeve (plastic tubing) is the most commonly used size on all brands of pinball machines. Measures 1-3/4 overall length x 1/2 inch shaft Outer Diameter. Typically found on pop bumper, slingshots, kickers, and early solid state and electromechanical flipper solenoid assemblies.

Marco also provides this information:  Coil Sleeve – 1/2 X 2-3/16 inch.  Nylon coil sleeve or tubing measures 2-3/16 x 1/2 inches shaft OD.  Typically used on Williams post-1980, Bally post-1988, Data East, Sega, and New Stern flipper coil assemblies.
