Potential Problem |
Possible Reason |
Solution |
| Voltage
not releasing. |
Faulty
switch. |
Replace
switch. |
| Rotor
and armature locked together. |
The clutch
has been severely galled and has locked up. (Galling is the condition
whereby a piece of metal is trapped between the armature and the rotor
and melts due to high pressure and heat, spot welding the surfaces together.)
|
If rotor
and armature connot be separated, replace the clutch. If they do separate,
follow burnishing procedure. |
| Pulley
bearing locked. |
Bearing
lost grease due to seal problem, temperature or water contamination.
(Example)
|
Replace
clutch. |
| Voltage
is going to the clutch but the clutch will still not engage. |
The
air gap is too large. (Example)
|
If
straight bore the air gap can be readjusted. If unit has set screw, bottom
out armature hub against field then back off to 0.1 inches and retighten
set screw. If spacers are used on straight bore reduce the width of the
spacer. If it’s a taper bore clutch tap on the armature cover plate
to close air gap. |
