When repairing, dismantling and reassembling the vehicle follow the recommendations reported below
carefully.
BEFORE REMOVING COMPONENTS
•Beforedismantling components, removedirt, mud,dust andforeign bodiesfrom thevehicle.
Use the special tools designed for this bike, as required.
COMPONENTS REMOVAL
•Donot loosenand/or tightenscrews and nuts using pliersor anyother toolsthan thespecific
wrench.
•Mark the positions on all connection joints (pipes, cables, etc.) before separating them, and
identify them with different distinctive symbols.
•Each component needs to be clearly marked to enable identification during reassembly.
•Clean and wash the dismantled components carefully using a low-flammability detergent.
•Keep mated parts together since they have "adjusted" to each other due to normal wear.
•Some components must be used together or replaced altogether.
•Keep away from heat sources.
REASSEMBLY OF COMPONENTS
CAUTION
BEARINGS MUST BE ABLE TO ROTATE FREELY, WITHOUT JAMMING AND/OR NOISE: OTH-
ERWISE, THEY NEED TO BE REPLACED.
•Only use ORIGINAL Aprilia SPARE PARTS.
•Comply with lubricant and consumables use guidelines.
•Lubricate parts (whenever possible) before reassembling them.
•Whentightening nuts andscrews,start eitherfrom thecomponentswiththe largestdiameter
or from the innermost components, proceeding diagonally. Tighten nuts and screws in suc-
cessive steps before applying the tightening torque.
•Always replace self-locking nuts, washers, sealing rings, circlips, O-rings (OR), cotter pins
and screws with new parts if the thread is damaged.
•When assembling the bearings, make sure to lubricate them well.
•Check that each component is assembled correctly.
•After a repair or routine maintenance, carry out pre-ride checks and test the vehicle on
private grounds or in an area with low traffic.
•Clean all mating surfaces, oil seal rims and gaskets before refitting. Smear a thin layer of
lithium-based grease on the oil seal rims. Reassemble oil seals and bearings with the brand
or batch number facing outward (visible side).
ELECTRIC CONNECTORS
Electric connectors must be disconnected as described below; failure to comply with this procedure
causes irreparable damage to both the connector and the cable harness:
Press the relevant safety hooks, if any.
