Replace control valve.
Lack of lubrication in the air chamber
Check air chamber lubrication. (See
LUBRICATION section.)
Using a rigid coupling connected directly
to the Drive Flange
Contact Nexen.
Failure to Disengage
Control valve malfunction or low air
pressure
Check system for air leaks or replace
control valve.

Tooth Wear or Clicking Sound
Excessive engagement RPM, or
unintentional disengagement due to
torque overload
Contact Nexen for specifications.
Bearing Failure
Stay within specified speed limits as specified in the OPERATIONS SECTION.
Avoid applying excessive overhung loads to Pilot Mount 5HP Tooth clutches. Wide
pulleys or sprockets which extend beyond the end of the clutch will increase the
radial load and reduce bearing life.
