REASSEMBLING THE COMPONENTS
DANGER
Never reuse a circlip or snap ring. These parts must always be replaced once they have been
removed.
When fitting a new circlip or snap ring, open the ends just enough to allow fitting to the shaft.
Make a rule to check that a newly fitted circlip or snap ring is fully housed in its groove.
Never use compressed air to clean bearings.
CAUTION All bearings must run freely with no hardness or noise. Replace any bearings that do not meet these
requirements.
- Use ORIGINAL aprilia SPARE PARTS only.
- Use the specified lubricants and consumables.
- Where possible, lubricate a part before assembly.
- When tightening nuts and bolts, start with the largest or innermost nut/bolt and observe a cross pattern. Tighten
evenly, in subsequent steps, until the specified torque has been achieved.
- Replace any self-locking nuts, gaskets, seals, circlips or snap rings, O-rings, split pins, bolts and screws which have
a damaged thread.
- Lubricate bearings abundantly before assembly.
- Make a rule to check that all components you have fitted are correctly in place.
- After repairing the motorcycle and after each service inspection, perform the preliminary checks, and then ride the
motorcycle in a private estate area or in a safe area away from traffic.
- Clean all mating surfaces, oil seal edges and gaskets before assembly. Apply a thin layer of lithium grease along the
edges of oil seals. Fit oil seals and bearings with the marking or serial number facing outwards (in view).
ELECTRICAL CONNECTORS
Disconnect electrical connectors as follows: failure to follow these instructions can seriously damage the connectors and
the wiring.
Press the special safety hooks, where fitted.
WARNING
Never separate two connectors by pulling on the wiring.
•
Grasp both connectors and pull them in two opposite directions until they become separated.
•
Remove dirt, rust, moisture, etc., from inside the connectors with compressed air.
•
Ensure that the wires are securely crimped to the terminals inside each connector.
CAUTION: A connector will fit properly only in the matching connector and when inserted in the correct fitting position.
•
Reconnect the two connectors. Make sure they are correctly coupled (if fitted with hooks, it should click audibly into
place).
TIGHTENING TORQUES
DANGER
Do not forget that the tightening torques of all wheel, brake, wheel shaft and other suspension parts
are essential to ensuring safe operation of the motorcycle and must be set to the indicated values.
Ensure that these values are always within the specified limits.
Regularly check the tightening torques on all fastenings, and always use a torque wrench when fitting
them.
Failure to observe these instructions can result in parts loosening or coming away, thus jamming a
wheel or creating other problems which would affect the handling of the motorcycle, potentially
resulting in serious injury or death.
