Maintenance rules

GENERAL PRECAUTIONS AND INFORMATION

When repairing, dismantling and reassembling the vehicle follow the recommendations reported below

carefully.

BEFORE REMOVING COMPONENTS

•

Before dismantling components, remove dirt, mud, dust and foreign bodies from the vehicle. Use the special tools designed for this bike, as required.

COMPONENTS REMOVAL

•

Do not loosen and/or tighten screws and nuts using pliers or any other tools than the specific 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.

Characteristics STELVIO 4V - 1200

CHAR - 8

•

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: OTHERWISE, THEY NEED TO BE REPLACED.

•

Only use ORIGINAL Moto Guzzi SPARE PARTS.

•

Comply with lubricant and consumables use 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 applying the tightening torque.

•

Always replace self-locking nuts, washers, sealing rings, circlips, O-rings (OR), cotter pins and screws with new ones if their tread 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 procedure, carry out pre-ride checks and test the vehicle on private grounds or in an area with low traffic density.

•

Clean all coupling surfaces, oil guard rims and gaskets before refitting them. Smear a light layer of lithium-based grease on the oil guard rims. Reassemble oil guards and bearings with the brand or lot 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.

•

Grip the two connectors and disconnect them by pulling them in opposite directions.

•

If any signs of dirt, rust, moisture, etc. are noted, clean the inside of the connector carefully with a jet of compressed air.

•

Ensure that the cables are correctly fastened to the internal connector terminals.

•

Then connect the two connectors, ensuring that they couple correctly (if fitted with clips, 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.

TIGHTENING TORQUES

CAUTION

IF UNSCREWING A SELF-LOCKING NUT, IT MUST BE REPLACED WITH A NEW ONE.

CAUTION

DO NOT FORGET THAT THE TIGHTENING TORQUES OF ALL FASTENING ELEMENTS ON WHEELS, BRAKES, WHEEL BOLTS AND ANY OTHER SUSPENSION COMPONENTS PLAY A

STELVIO 4V - 1200 Characteristics

CHAR - 9

KEY ROLE IN ENSURING VEHICLE SAFETY AND MUST COMPLY WITH SPECIFIED VALUES.

CHECK THE TIGHTENING TORQUES OF FASTENING PARTS ON A REGULAR BASIS AND AL-

WAYS USE A TORQUE WRENCH TO REASSEMBLE THESE COMPONENTS. FAILURE TO COM-

PLY WITH THESE RECOMMENDATIONS MAY CAUSE ONE OF THESE COMPONENTS TO GET

LOOSE AND EVEN DETACHED, THUS BLOCKING A WHEEL, OR OTHERWISE COMPROMISE

VEHICLE HANDLING. THIS CAN LEAD TO FALLS, WITH THE RISK OF SERIOUS INJURY OR

DEATH.

Running-in

Engine run-in is essential to ensure engine long life and correct operation. Twisty roads and gradients

are ideal to run in engine, brakes and suspensions effectively. Vary your riding speed during the run-

in. This ensures that components operate under both "loaded" and "unloaded" conditions, allowing the

engine components to cool.

CAUTION

THE CLUTCH MAY EMIT A SLIGHT BURNING SMELL WHEN FIRST USED. THIS PHENOMENON

SHOULD BE CONSIDERED NORMAL AND WILL DISAPPEAR AS SOON AS THE CLUTCH

PLATES GET ADAPTED.

IT IS IMPORTANT TO STRAIN ENGINE COMPONENTS DURING RUN-IN, HOWEVER, MAKE SURE

NOT TO OVERDO THIS.

CAUTION

THE FULL PERFORMANCE OF THE VEHICLE IS ONLY AVAILABLE AFTER THE SERVICE AT

THE END OF THE RUNNING IN PERIOD.

Follow these guidelines:

•

Do not twist the throttle grip abruptly and completely when the engine is working at a low revs, either during or after run-in.

•

During the first 100 Km (62 miles) use the brakes gently, avoiding sudden or prolonged braking. That is to permit the adequate adjustment of the pad friction material to the brake discs.

AFTER THE SPECIFIED MILEAGE, TAKE THE VEHICLE TO AN OFFICIAL Moto Guzzi DEALER

FOR THE CHECKS INDICATED IN THE "AFTER RUN-IN" TABLE IN THE SCHEDULED MAINTE-

NANCE SECTION TO AVOID INJURING YOURSELF, OTHERS AND /OR DAMAGING THE VEHI-

CLE.

Assembly clearances

Cylinder - piston assy.

Measurement of the cylinder diameter must be done at three heights, turning the dial gauge 90°. Check that cylinders and pistons are of the same selection types (D, E, F). Check clearance between cylinders and pistons on the selected diameter; if it exceeds the value specified, it is necessary to replace cylinders and pistons. The pistons of an engine must be balanced; a weight difference of up to 1.5 g (0.0033 lb) is allowed.
