Pulley Alignment - Porter-Cable PXCMLC1683066 Instruction Manual

PULLEY ALIGNMENT

To check pulley alignment, remove the belt guard and place a straightedge
(see A) against the pump flywheel (see B) (See Fig. 9). Measure and record the
distance from the straightedge to the edge of the drive belt at point C. Then
measure the distance from the straightedge to the edge of the drive belt again
at points D and E. Both distances should be the same as at point C. If D or E
are different from C, there is a misalignment which must be corrected before
the compressor is run. To correct a pulley misalignment, use the following
procedure.
1. Remove the belt guard.
2. Loosen the motor mounting bolts.
3. Loosen the setscrew on the motor pulley.
Align the motor pulley with the pump flywheel (C = D = E).
4.
5. Retighten the motor pulley setscrew.
6. Adjust the proper belt tension.
7. Retighten the motor mounting bolts.
8. Reinstall the belt guard. All moving parts must be guarded.
