• WASHERS, O-RINGS AND OIL SEAL
1. During the revision of the engine, change all the washers, O-rings and seals.
The surfaces of the washers and O-rings, and the lips of the oil seals must be
cleaned.
2. Oil all the coupled components and the ball-bearings and grease the lips of the
seals, when remounting.
• ELASTIC SAFETY WASHERS/PLATES AND SAFETY PINS
After removing, change all the elastic safety washers and safety pins. After tightening
the bolts or nuts, bend the tongues of the safety washers/plates and the ends of
the safety pins on a flat surface of bolts or nuts.
• BALL-BEARINGS AND OIL SEALS
WARNING:
Do not rotate the compressed air ball-bearings as this might damage
their surfaces.
1. Install the ball-bearings and the oil seals so that the Producer brand or data are
visible. At the moment of installing the oil seal, oil the lip with a slight layer of
grease. The ball-bearings rotate freely if oiled in an appropriate way.
