SXV / RXV 450 – 550
DISASSEMBLING THE COMPONENTS
- Never use pliers or similar tools to slacken and/or tighten nuts and bolts. Always use the suitable wrench.
- Mark all connections (hoses, wiring, etc.) with their positions before disconnecting them. Identify each connection
using a distinctive symbol or convention.
- Mark each part clearly to avoid confusion when refitting.
- Thoroughly clean and wash any components you have removed using a detergent with low flash point.
- Mated parts should always be refitted together. These parts will have seated themselves against one another in
service as a result of normal wear and tear and should never be mixed up with other similar parts on refitting.
- Certain components are matched-pair parts and should always be replaced as a set.
- Keep away from heat sources.
REASSEMBLING THE COMPONENTS
DANGER
Never reuse a circlip or snap ring. These parts must always be renewed once they have been
removed.
When fitting a new circlip or snap ring, take care to move the open ends apart just enough to allow
fitting 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.
NOTE 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 operate
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.
NOTE 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 problems affecting vehicle
maneuverability, creating a risk of falling, serious injury or death.
