Maintenance
5-5
Required Tools:
• # 1 posidriv screwdriver
• Spindle motor adjustment tool PIN 8710-1385
Refer to Figure 5-2 while performing these steps:
1.
Place the drive assembly on its side so that the bottom of the drive faces you.
2. Remove the drive belt.
3. Place the spindle motor adjustment tool on the bottom of the drive as shown in Figure
5-2 so that the smallend of the adjustment tool rests against the motor pulley and the
large end rests against the spindle pulley.
4. Slightly loosen the spindle motor retaining screws and move the motor until it rests
firmly against the adjustment tool.
5. Re-tighten the spindle motor retaining screws and reinstall the drive belt.
NOTE
There is a good chance that the drive motor is not exactly perpen-
dicular to the drive casting on which it is mounted. This will cause
the drive belt to slip from the drive pulley when it is rotated. After
a belt is installed, rotate the drive spindle approximately 10 re-
volutions to insure the belt will not slip from the drive pulley.
