9.8.3 Align the Drive Belt
A laser alignment tool or 50" (127 cm) straight edge
is necessary for this procedure. A laser alignment
tool is the most accurate.
Check the drive belt alignment after every 8 hours of
operation.
The maximum misalignment is 1/32" (1 mm).
1. Put a straight-edge tool across the face of the rotor sheave.
Point the opposite end of the straight-edge toward the
engine clutch flywheel.
Make sure that the straight-edge is parallel with the face of
the rotor sheave. See
Figure 40.
2. Do one of the following:
• If the edge of the engine clutch flywheel aligns with the
straight-edge, the drive belt is aligned. The following
steps are not necessary. See
Figure 40.
• If the edge of the engine clutch flywheel is parallel to
the straight-edge tool, but is not aligned with the rotor
sheave, align the rotor sheave. See
Figure 42 on page
56.
For instructions, see Align the Rotor Sheave on page
59.
• If the edge of the engine clutch flywheel is not parallel
(is on an angle) to the straight-edge tool, align the
engine clutch. See
Figure 41 on page 55.
For instructions, see Align the Engine Clutch on page
59.
3. Do steps 1 and 2 again to make sure the drive belt is
aligned.
