NOTE
Run the engine to circulate the oil and
check for leakage. Time must then be al-
lowed for the oil to settle in the sump
before rechecking the level. Top up if
necessary.
WARNING
In hard work conditions and low fuel
quality, change the engine oil and oil filter
every 125 hour or 6 months whichever is
the sooner.
Valve tip clearances (Fig. 14)
Check the valve tip clearances eve-
ry 1000 hours.
The valve tip clearance is set between
the top of the tappet and the rocker lever.
The correct clearances (engine cold)
are:
Three cylinder naturally aspirated engines:
0.30 mm (0.012 in) inlet and exhaust.
To check the clearances proceed as
follows:
1. Turn the crankshaft in the normal di-
rection of rotation until the inlet valve
of number 1 cylinder has just opened
and the exhaust valve of the same cyl-
inder has not closed completely.
2. Check the clearances of valve numbers
4 and 6 and adjust them, if it is neces-
sary.

3. Make a mark on the crankshaft pul-
ley and the timing case and turn the
crankshaft one complete revolution
(360

) until the marks align again.
