4.7.13.e CHANGING THE BALL-BEARING RING PINION LUBRICANT
4.7.13.f CHECKING THE ALTERNATOR AND THE STARTER
• Oils, filters, coolants and batteries are considered special waste and must be collected and disposed of
according to the anti-pollution regulations in force.
IMPORTANT
• The lubricant must be changed with the machine at rest and at the end of work, that is, with the machine
at operating temperature.
To change the lubricant, proceed as follows:
1 - Remove the inlet and inspection cover (1) and the drain plug
(2) after preparing a container suitable for collecting the used
grease that flows out of the drain hole. Use a 17 mm spanner.
2 - Complete the removal of used grease by means of a suction
pump.
3 - Put back the drain plug (2).
4 - Inject the prescribed grease (see “4.3 FUEL, COOLANT AND
LUBRICANTS”) through the inlet hole (1) until reaching half
the height of the ball-bearing ring teeth (approximately 100
mm).
5 - Put back the inlet and inspection cover (1) and after approxi-
mately two hours of operation make sure that the lubricant lev-
el is correct.
