26
27
- Fit a new cylinder gasket.
- Fit the cage bearing to the connecting rod little end.
PISTON RINGS
- Fit the piston rings into the cylinder and use the piston to push them a little way in, until they are perpendicular to the longitudinal axis of the cylin­der.
- Measure the gap between the ends of the piston rings using feeler gauges.
The maximum permissible value is 0.5 mm.
PISTON
- Measure the exterior diameter of the piston at a point situated 15 mm from the base of the piston.
- Calculate the play between the cylinder and the piston.
The service limit is 0.06 mm.
Fit the piston rings onto the piston.
- “First fit the expansion ring, and then the lower ring”. It is rectangular in section, and finally, fit the upper piston ring “which has a trapezoidal section”.
- Fit the piston and keep the arrow on the upper surface of the piston facing towards the exhaust port.
- The piston is assembled onto the connecting rod by first inserting the little end cage bearing into the little end of the connecting rod, then the gud­geon pin and securing it by means of the circlips, using special tool 0.0G.056.0.041.1.
- When fitting the cylinder it is recommended to apply a little oil to the part, and to the piston rings and to the piston so as to make assembling the cylinder over the piston easier. The recommen­ded oil is that used for the fuel mixture.
CYLINDER HEAD, CYLINDER, AND PISTON
- The cylinders of the monobloc models cannot be rectified, and there are no oversizes. There are only families of cylinders and pistons, which go in steps of 0.005 mm.
- When replacing the piston, the family identifica­tion stamped on the cylinder should be identified, and a piston of the same letter as on the cylinder should be used.
Table of tolerances for cylinder and piston
CYLINDER HEAD
- Check the contact surface (the sealing surface) of the cylinder head by resting it on a surface plate; using a feeler gauge check that there is no grea­ter gap than 0.05 mm.
- For the engine to run properly it is very important that the cylinder head-cylinder joint, and the she­athing should be perfectly gas-tight.
- If the gap between the two parts is higher that the value quoted above, then it will be necessary to grind down the surface on abrasive paper resting on a surface plate, moving it in figures of eight as shown in the diagram.
- Models HUNTER, PADDOCK, and VAMOS: in these models the cylinder head gasket should be fitted with the convex exterior border facing upwards.

BATTERY
- When the battery is used for the first time, it is necessary to fill with the acid which comes toget­her with the battery.
- First remove the sealing strip.
- Next place the container of electrolyte upside down with the six sealed parts aligned with the six filler holes on the battery. Push the container firmly down to break the seals.
- Check that all the electrolyte has gone into the battery.
Sealing up the battery:
- Push the sealing strip firmly into each of the filler holes.
- Never remove the sealing strip, and never add water to the electrolyte.
- The battery is a 12V 4 Ah type. When installing the battery it is important not to reverse the pola­rity of the terminals, since this could cause dama­ge to some sensitive electronic components.
Using the battery for the first time:
- This battery is a sealed type and the cell covers should never be removed, and water must never be added.
- After 30 minutes test the voltage at the terminals.
Standard voltage 12.5 volts minimum
Under normal circumstances it is not necessary to charge the battery. Once charged it is normally at 75% capacity.
Special conditions under which the battery
should be charged:
- When the temperature falls below 0 ºC.
- After a long period in storage.
- When the original seal has been broken.
- In general the battery should be charged whene­ver the voltage after charging remains below the standard reading of 12.5 V.
CHECKING THE ELECTRICAL SYSTEM IN THE SCOOTER
64
STARTER RELAY
- Check the resistance between each of the termi­nals.
- Resistance between 85 and 86 = 55 Ω±15%.
- In order to measure continuity between the con­tacts, connect poles 85 and 86 to the battery and pole 30 and 87 to the tester: the result of this test should be a reading of 0 ohms (closed circuit). When poles 85 and 86 are disconnected from the battery, the tester should read infinity, or open cir­cuit.
- If there is any variation from these readings, the relay should be replaced.

All operations to check the wiring which involve disconnecting cables (checking connections and devices which form part of the ignition circuit) must
be performed with the engine switched off:
otherwise the central unit may suffer irreparable damage.
These checks should be performed if the ignition is irregular, or if there is no spark at the spark plug.
1)Check the spark plug (clean with wire brush, remove soot, blow clean with compressed air, if necessary replace).
2) Without stripping the stator, perform the follo­wing check:
After visual examination of the electrical connec­tions, measure the characteristics of the coil and the pick-up (see table).
If any anomalies appear when checking the coil and the pick-up, replace the stator and the dama­ged parts.
Remember that in order to replace the central unit, cables must only be disconnected with the engine switched off.
