1 Taito Ice Cold Beer
1.1 Florescent Lamp
The original playfield lamp is an F15T12. The fluorescent light degrades the paint on the backglass. The florescent tube can be replaced with a modern LED, such as TBD.

1.5 Motor Replacement
Replacement motors for Ice Cold Beer were available from Twisty Arcade a few years ago. The installation procedure for this motor, or an equivalent can be found below. The principle part of the job is to transfer the gear from the old motor shaft to the new motor shaft, and modify the motor bracket to mate to the new motor.
The motor from Twisty Arcade came with a 6.2ohm, 5W resistor. It may be necessary to replace this part with a 10ohm, 5W resistor to slow the motor a bit more. If your game raises the bar too far to "serve" the ball, install a replacement resistor of perhaps 8.2ohm, 5W, or even the 10ohm part.
- Taito Ice Cold Beer Replacement Motor Installation
The replacement motor to be installed. The motor comes with an inline current limiting resistor (6.2ohm, 5W) to slow the new motor speed to close to the original motor speed. 
The OEM bracket, showing 4 motor attach points. 
The OEM Motor, showing the gear to be transferred to the new motor. 
Use a hack saw to cut the shaft off the original motor. 
Position the shaft/gear in a vise but don't tighten the vise on the shaft. Punch out the old shaft. 
With the "tail" of the new motor shaft on a solid surface, gently tap the original gear onto the new motor shaft. 
The original gear, installed on the new motor shaft. Note that the shaft doesn't quite come to the gear edge, so that it mates correctly when installed into the gearbox. 
Enlarge the hole in the original bracket to 13mm. Here a 1/2" bit in a drill press (clamp the part down before drilling) is used to remove most of the material... 
...and then a rat tail file is used to complete the enlargement. 
The original bracket, deburred, and installed on the new motor. Two screws are sufficient to hold the motor in place. 
A view of the new motor and original gear, perfectly aligned with the motor gearbox. 
The new motor, in place, ready to go.
