REASSEMBLING THE COMPONENTS
DANGER
Never reuse a circlip or snap ring. These parts must always be renewed once they have been
disturbed.
When fitting a new circlip or snap ring, take care to move the open ends apart just enough to allow
fitment to the shaft.
Make it a rule to check that a newly-fitted circlip or snap ring has located fully into its groove.
Never clean a bearing with compressed air.
CAUTION All bearings must rotate freely with no hard spots 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 achieving the specified torque.
- Replace any self-locking nuts, gaskets, seals, circlips or snap rings, O-rings, split pins, bolts and screws which have
a damaged thread.
- Lubricate the bearings abundantly before assembly.
- Make it 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
To disconnect the electrical connectors, follow the procedures below. Failure to comply with these procedures may lead
to irreparable damage to the connector and the wiring as well.
If present, press the special safety hooks.
WARNING
Do not pull cables to disconnect the two connectors.
•
Grasp the two connectors and disconnect them by pulling them in the two opposite directions.
• In case of dirt, rust, moisture, etc.., thoroughly clean the inside of the connectors with compressed air.
• Make sure that the cables are correctly fitted inside the connector terminals.
CAUTION The two connectors have just one correct positioning. Make sure to position them in the right direction.
• Then fit the two connectors. Make sure they are correctly coupled (a click will be heard if hooks are present).
TIGHTENING TORQUE SETTINGS
DANGER
Always remember that the tightening torque settings of all wheel, brake, wheel shaft and other
suspension parts play a fundamental role to ensure vehicle safety. Make sure that these values are
always within the specified limits.
Check fastening parts tightening torque settings at regular intervals. Upon reassembly, always use a
torque wrench.
Failure to comply with these recommendations could lead to the loosening and detachment of one of
these parts with a consequent locking of the wheel or other serious troubles affecting the vehicle
manoeuvrability, and thus the risk of falls and serious injuries or death.
