TUONO 1000
DISASSEMBLING THE COMPONENTS
- Never use pliers or similar tools to loosen and/or tighten nuts and bolts. Always use a suitable spanner.
- Mark the positions of all connections (hoses, wiring, etc.) 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 replaced with new ones 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.
NOTE 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 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 test 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 outward (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 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.
NOTE A connector will fit properly only in the matching connector and when inserted in the correct fitting position.
• Reconnect the two connectors. Ensure that they are correctly coupled (if fitted with hooks, they should click
audibly into place).
TIGHTENING TORQUES
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. Ensure that these values are
always within the specified limits.
Check the tightening torque settings of fastening parts at regular intervals. Always use a torque
spanner when reassembling.
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.
