Preventive Maintenance Transmission and Clutch
Model 330 PB1318 3/01

Standard Transmission Oil Level
NOTE: The vehicle must be parked on level ground.
• Maintain the oil level and check it regularly. Oil should be
up to bottom of filler plug hole.
Clutch System Introduction
Free pedal is the distance the clutch pedal moves by applying
only slight pressure. During free pedal the release yoke in the
transmission moves until its bearing pads contact the release
bearing. This movement of the release yoke is called free
travel. Thus, free pedal and free travel are directly related to
each other.
