PROCEDURE
DANGER
Park vehicle safely, apply parking brake, stop engine. Prior to working on the vehicle, set the ignition
switch to the OFF position and trip the main circuit breakers equipped with a trip button. On Commuter
type vehicles, set the battery master switch (master cut-out) to the OFF position.
PRELIMINARY CHECK
1. Before starting the installation, check the air
gap (working gap) between the armature and
the clutch.
Air gap (working gap) should be:
between 0.024 & 0.035 in (0.60 & 0.90 mm)
Lang clutch working gap is factory set and not
adjustable. If the working gap is out of
tolerance, reject the electromagnetic clutch.
You must prevent the penetration of greasy
liquids, grease or dirt particles in the working
gap of the clutch.
