Maintenance rules

GENERAL PRECAUTIONS AND INFORMATION

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

carefully.

BEFORE DISASSEMBLING 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 other tools other than the especially designed wrench.

•

Mark positions on all connection joints (pipes, cables, etc.) before separating them, and identify them with distinctive symbols.

•

Each component needs to be clearly marked in order to be identified during assembly.

•

Clean and wash the removed components carefully using a low-flammability detergent.

CHAR - 8

GRISO 8V - 1200 Characteristics

Revente Interdite - Revendita Vietata - Resaling Forbiden - Wiederverkauf Verboten

•

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, OTHERWISE 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 applying 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 vehicle 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 bearings 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.

•

If there are signs of dirt, rust, humidity, etc., clean the connector 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.

TIGHTENING TORQUE

CAUTION

CHAR - 9

Characteristics GRISO 8V - 1200

Revente Interdite - Revendita Vietata - Resaling Forbiden - Wiederverkauf Verboten

DO NOT FORGET THAT THE TIGHTENING TORQUE OF ALL FASTENING ELEMENTS ON

WHEELS, BRAKES, WHEEL SPINDLES AND OTHER SUSPENSION COMPONENTS PLAY A KEY

ROLE IN ENSURING THE VEHICLE'S SAFETY AND MUST COMPLY WITH SPECIFIED VALUES.

CHECK THE TIGHTENING TORQUE 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 driving speed during run-in.

In this way, you allow for the work of components to be "loaded" and then "unloaded", thus cooling

engine parts.

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

ONLY AFTER THE SERVICE AT THE END OF THE RUN-IN PERIOD CAN THE BEST PERFORM-

ANCE OF YOUR VEHICLE BE OBTAINED.

Follow the guidelines detailed below:

•

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) operate the brakes with caution, avoid rough and long 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" TABLE IN THE SCHEDULED MAINTE-

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

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.
