Magnet Clutch Operating Check




Check the following items.
If any detects are found, repair or replace magnet clutch assembly.
- Inspect pressure plate and rotor for signs of oil.
- Check clutch bearings for noise and grease leakage.
- Using an ohmmeter (3), measure resistance of stator coil between clutch lead wire (1) and body ground (2).
If measured resistance is not within tolerance, replace coil.

Specified current of magnet clutch: 3.4 - 4.6 Ohms at 25 °C (77 °F)
