Installing the shaker mechanism is a generic task that works across many
machines. The main thing is finding a place for it where the wiring works well.
The shaker motor has enough power that we don't have to worry too much about
position.
 There
are two likely candidates for the location for a shaker motor in WPC-95
machines. Use this location if you do not plan to install a larger
speaker. |
 In
this machine, the motor is installed where the cabinet cheat sheet
goes. |
 For
earlier machines, the motor has to go between the cashbox divider and
the transformer brace. If you wish, you could try 1/2" #10 woodscrews to
the brace. Make sure that you have room to install the covers. You'll
need 1/2" clearance. |
|
 Here's
the template (yours may be clear, and stiff enough to hold in place with
a screw). Set it in the cabinet and make sure that it is square and
clear of obstructions. You can put the motor on it to check for
clearance. |
 Here's
a box under the playfield to catch debris. |
 First,,
we drill four pilot holes from the top. Use a small drill bit. |
 Then
we follow up with four 1/4" holes for the tee nuts. |
 Place
the tee nuts in the hole. Pound them in with a hammer. Don't try to jack
them in with a screwdriver. The cabinet wood is too hard, and you will
bend the prongs and damage the threads. |
 Screw
the motor in. Make it snug, don't overtighten. |
 Finally,
install the covers. Clip them on the bottom screws first, then lever the
top flaps with a screwdriver. They are a tight fit. You can lock them in
place with the black push rivets if you like, but this is probably
unnecessary. They are hard to remove: you will need to lever the flaps
out with a screwdriver, so don't put them in until you are done. |
