4.2.6 Readjustment V-belt
The alternator bracket allows to readjust the V-belt. De-
flections should be 10 mm (refer to fig. 16).
4.3 REGULAR MAINTENANCE
CHECK DAILY:
• Oil level (see fig. 17)
Take care the oil level is never
below the mark. Do not add oil
when the level is still above the
mark.
CHECK DAILY:
• Level cooling liquid.
• Hoses for loose connections or deterioration.
AFTER FIRST 50 HOURS:
• Change oil and replace the oil filter.
Have the engine run until it is on temperature and
stop it. Drain oil by the sump pump into a suitable
retainer and fill up with fresh oil. Start the engine
again and have it run for 5 minutes. Stop the engi-
ne again and pause for a few minutes to let the oil
gather in the crankcase. Check the level again
and add oil when necessary.
• Check and tighten nuts, bolts, and unions, paying
particular attention to the fuel system.
• Retighten the cylinder head bolts and adjust the
valve clearance. (Refer to page 65; 5.4.2)
• Observe the exhaust at the normal full load. The
exhaust must be free from soot. Do not allow the
engine to run with a dirty exhaust without investi-
gating the cause as this may result in an expensi-
ve breakdown.
• Check and readjust V-belt.
EVERY 150 HOURS:
• Change oil.
• Check the battery acid level.
• Check battery terminals for corrosion
• Check and readjust V-belt.
EVERY 300 HOURS:
• Check the impeller of the water pump.
• Check valve clearance.
• Replace the oil filter.
• Replace the fuel filter
Replacement depends or the condition of the fuel.
We recommend replacement every 300 hours.
Isolate the fuel supply and change the element.
EVERY 500 HOURS:
• Replace the impeller of the water pump.
When replacing the impeller the gasket between the
pump case and the cover should be replaced as well.
So when ordering a spare impeller, order a gasket as
well. Remove the cover to get access to the impeller. Re-
move the old impeller with the help of two screwdrivers.
Install the new impeller and add some grease. Turn the
blades in the direction of rotation of the pump i.e. anti
clockwise looking at the impeller.
