MAINTENANCE SCHEDULE
DAILY OR EVERY 8 HOURS RUNNING
• Check engine oil level.

AFTER THE FIRST 25 HOURS RUNNING
• Change gearbox lubricant (See separate gearbox
manual).
• Check that all external nuts, bolts and fastenings are
tight. See table for torque values. Do NOT over
tighten. Special attention should be paid to the flexible
mount lock nuts, these should be checked for
tightness, starting with lower nut first in each case. If
the lower nuts are found to be very loose, then the
alignment of the shaft to the gearbox half coupling
should be re-checked. Poor alignment due to loose
flexible mount nuts will cause excessive vibration and
knocking.
• Check the belt tension on any second alternators fitted
and adjust, see page 11.

gearbox and speed control levers. Grease both fittings
