CHANGES
noting each wire's coil terminal.
Improvements to the Upper Diverter Assembly,
p/n C-13489, include;
(1) a coil change (replace the AE-23-800 coil with
one marked AE-26-1200);
(2) a Solenoid Bracket Assembly. p/n B-13488,
change and
(3) a change to the assembly comprising the coil
plunger, drive link and spring.
B. Remove the solenoid bracket Mounting
ORDER
It is suggested that these changes occur in the
order listed in the preceding paragraph; that is,
coil replacement should be first, followed by
replacing the Solenoid Bracket Assembly. If nec-
essary, the more complex change of the coil
plunger, drive link, and spring should resolve all
associated problems with the Upper Diverter
Assembly.
See the accompanying diagram for details. The
parenthetical numbers in the following proce-
dure refer to the diagram's parts. (Some parts
shown in the Rollergamesmanual (p. 61) are not
used in this new assembly.)
PROCEDURE
NOTE: The following procedures require access
to the upper portion of the playfield; however,
the playfield can remain in the game, while the
work is being done, and none of the playfield
cables requires disconnection.
• Turn OFF the game. • Remove the playfield
glass. • Lift the playfield from its tilting hinge
brackets, until the upper portion is accessible.•
Place the playfield on the cabinet carefully to
avoid damaging any parts. • Remove the screws
mounting the plastic shield to the end of the
playfield.
Screws (19), retaining them for reassembly.
C. Remove theAE-23-800 Coil (1). and replace it
with an AE-26-1200 Coil.
D. Replace the Solenoid Bracket Assembly, p/n
B-13488, (3) with a new revision A Assembly.
(The revision A Solenoid Bracket Assembly has a
slightly shorter solenoid stop than the original
assembly.)
E. Mount the Coil (1) and Solenoid Bracket
Assembly (3), as they were on the original unit;
install and tighten the bracket Mounting Screws
(19), using Loc-Tite.
F. Solder the wires to the new Coil, connecting
them to the proper terminals (noted in step A).

A. Remove the two "E" Rings attaching the old
Diverter Drive Link to the two black, plastic Arm
Assemblies; retain these "E" Rings for
reassembly.
B. Remove the spring at the end of the old Drive
Link; remove the old Drive Link, including the
spring-attached Coil Plunger.
C. Replace all of the old Drive Link parts (coil
plunger, springs, etc.) with the new Link-
Plunger-Spring Assembly (10), p/n B-13843,
sliding the plunger into the coil and inserting the
post of each Arm Assembly (7) into the proper
hole of the new Link-Plunger-Spring Assembly.
D. Attach an "E" Ring on each Arm Assembly
post to reassemble the Link-Plunger-Spring
Assembly. Slip the loop of the Spring into the
hole of the Diverter bracket, where the old spring
was removed.
E. Move the updated Diverter Assembly back
and forth several times to verify that it is moving
