•Do not loosen and/or tighten screws and nuts using pliers or other tools other than the
especially designed wrench.

•Keep coupled parts together since they have "adjusted" to each other due to normal wear
and tear.
•Some components must be used together or replaced altogether.
•Keep away from heat sources.
REASSEMBLING COMPONENTS
CAUTION
BEARINGS MUST BE ABLE TO ROTATE FREELY, WITHOUT JAMMING AND/OR NOISE, OTH-
ERWISE THEY NEED REPLACING.
•Only use ORIGINAL Moto Guzzi SPARE PARTS.
•Comply with lubricant and consumables usage guidelines.
•Lubricate parts (whenever possible) before reassembling them.
•When tightening nuts and screws, start from the ones with the largest section or from the
internal ones, moving diagonally. Tighten nuts and screws in successive steps before ap-
plying the tightening torque.
•Always replace self-locking nuts, washers, sealing rings, circlips, O-rings, split pins and
screws with new ones if their tread is damaged.
•When fitting bearings, make sure to lubricate them well.
•Check that each component is fitted correctly.
•After a repair or routine maintenance procedure, carry out pre-ride checks and test the ve-
hicle on private grounds or in an area with low traffic density.
•Clean all junction surfaces, oil guard rims and washers before refitting them. Smear a light
layer of lithium-based grease on the oil guard rims. Reassemble the oil guard and the bear-
ings with the brand or lot number facing outward (visible side).
ELECTRIC CONNECTORS
Electric connectors must be disconnected as described below as non-compliance with the procedure
so described causes irreparable damage to both the connector and the cable harness:
Press the relevant safety hooks, if any.
•Grip the two connectors and disconnect them by pulling them in opposite directions.
•Ifthereare signs of dirt, rust, humidity, etc.,cleantheconnector internal parts carefully using
a pressurised air jet.
•Make sure that the cables are correctly linked to the connector internal terminal ends.
•Then insert the two connectors making sure that they couple correctly (if the relevant hooks
are provided, you will hear them "click" into place).
CAUTION
TO DISCONNECT THE TWO CONNECTORS, DO NOT PULL THE CABLES.
NOTE
THE TWO CONNECTORS CONNECT ONLY FROM ONE SIDE: CONNECT THEM THE RIGHT WAY
ROUND.
