(2)
Changing of engine oil
To change the engine oil, warm up the engine.
Shut it down and
then remove the oil dr ain hose from its suppor t
br acket at the
front of the engine.
Two wrenches are needed to do this one to
hold
the
fitting
on
the
hose
and
the
other
to
unscrew
the
securing cap.
Lower the hose into a container large enough to
hold the oil and allow the sump to drain.
A pump may be used to
draw the oil out through this hose.
When the sump is completely
drained,
reposition
the drain hose on its support bracket and
replace the hose cap/plug and tighten securely.
Refill the engine oil sump with the correct amount of oil as spe-
cified in the data section of this manual.
NOTE:
Check
the
oil
level
reading
on
the oil
sump dipstick.
Allow a few minutes after adding the new oil for
it to settle
into the oil sump.
Oil Filter
The oil filter
is an easy-to-handle cartr idge type filter with the
filter body and element formed integral.
If the element has been contaminated or clogged and the oil pressure
difference before and after
the element has become more than about
1 kg/cm 2 , the built-in relief valve opens to allow the oil to flow to
each part of the engine wi thout passing through the oil filter ele-
ment.
Therefor e, it is impor tant to check and change the oil regu-
larly.
The filter interior requires no cleaning.
The filter must be
replaced with a
new one every 100 hours of operation
(initally at
50 hours).
Removal and Replacement of Oil Filter
If it is difficult to remove the filter by hand, use a special tool
(commercially available) or wrap a V-belt around it.
To install, tighten the oil filter fully by hand.
Tightening torque:
1.1 to 1.3 kg-m
Confirm
that
the O-ring
is
properly fitted
in
the O-ring
groove.
Apply a thin coat of engine oil to the O-ring.
Prior to installing
the filter on the engine, run the engine after filling with oil and
check for pressure and leaks.
Check the oil level after shutting the
eng ine off and add oil to br ing the level up to the full mar k as
needed.
