Component Tests
FIELD COIL WIRE
If the field coil wire is broken, replace field coil. Check amperage and voltage. The amperage rangerequirements is 3.6 to 4.2 amps at 12 volts.
- A very high amperage reading indicates a short within the field coil.
- No amperage reading indicates an open circuit in the winding.
- An intermittent or poor system ground results in lower voltage at the clutch. Check for tight fit of coil retaining snap ring or coil retaining screws for ground.
CLUTCH AIR GAP
An incorrect air gap could cause erratic engagement or disengagement and/or clutch rattle. Check the air gap with a feeler gauge. Air gap should be, (0.016-0.031inchs)
BEARING NOISE
If bearing noise is suspected perform the following:
- Remove belt. Disengage clutch.
- Rotate clutch pulley by hand.
Listen for bearing noise. Feel for hard spots. If excessive, replace clutch pulley and clutch front plate assembly or bearing set.
