SPARK PLUG MAINTENANCE
• Spark plug maintenance consists essentially of a periodical visual inspection. Remove the
spark plug and check for proper condition and gap.
• Clean the electrodes and the insulator thoroughly by means of a wire brush.
• Remove any residual dirt with a strong jet of compressed air.
• Lubricate spark plug thread with engine oil or graphitised grease, and install it by hand until
finger tight.
Tighten to the specified torque with a spark plug wrench (see F-6).
It is imperative that any spark plug exhibiting cracks on the insulator or corro-
ded electrodes be replaced.
SPARK PLUG REPLACEMENT
5000 km
• Upon prescribed mileage being reached, always replace the spark plug. Use RIEJU,
S.A. recommended spark plugs.
• When replacing exhausted spark plugs, visually inspect spark plug condition as described
above to ascertain whether or not the engine is running properly.
ENGINE REMOVAL
• For removal of the engine from the chassis, refer to the "Chassis" Workshop Manual,
which lists all the operations required.
