Sealey SM14 - Manual (Page 3)

5.6. CHANGING DRIVE BELT
5.6.1. Remove the circular sanding disc to gain access to the allen bolt that secures the aluminium sanding plate.
5.6.2. Remove the allen bolt and washer (fig.4), followed by the bolt cup (fig.5), you can then see the Woodruff Key (fig.6). When refitting the
disc plate you must align the groove in the disc with the Woodruff Key.
5.6.3. When the disc has been removed, undo the lower cover screw (fig.7) and the upper cover screw (fig.8), remove the disc belt cover.
5.6.4. Remove the old belt.
5.6.5. Fit the new belt over the lower motor spindle pulley and over the top pulley as in fig.9. To help engage the belt pulley with the top
pulley teeth, rotate the motor spindle anti-clockwise while applying horizontal pressure to the belt at the top pulley (fig.9). Ensure the
belt is correctly located on both pulleys. Fig.10 shows the belt in the correct location on the upper pulley.
5.6.6. The correct belt tension is shown in fig.11, with a firm pressure you should be able to squeeze the belt 5mm on each side. DO NOT
over tighten as this will damage the motor bearings and belt. The belt should not be slack as it may run off the pulleys during use.
The belt tensioners are shown in fig.12 - two horizontal adjusters and fig.13 - vertical adjuster.
5.6.7. When squeezing the belt; if the motor pulley rises, adjust the vertical adjuster (fig.13) until there is no more vertical play in the motor.
Note: When you are satisfied the belt tension is correct, turn the belt through a couple of revolutions to ensure belt, pulleys etc. all turn
freely.
5.6.8. Re-assembly is a reversal of procedures 5.6.1 to 5.6.3.
