The installation of the exhaust system should consist
of the following:
Personnel protection from hot surfaces.
Adequate supports to prevent strain on the
engine exhaust outlet and minimize
vibration.
Protection against entry of water and other
foreign matter.
While the engine is running inspect exhaust pipe
outlet outside of the pump room itself for
environmental hazards such as excessive smoke
conditions. The following could be used as a guide
for general engine operating conditions.
1) Blue Smoke – Possible engine oil
consumption.
2) White Smoke – Possibility of water in
cylinders, water in fuel or internal engine
problem.
3.3 LUBRICATION SYSTEM
3.3.1 Checking Sump Oil
Check the sump oil level using the dipstick on the
engine as shown in Figures #18A and 18B.
This level must always be between the dipstick marks
Min. and Max. with the engine not running. On
DT2H engines the dipstick should be reinserted for
measurement very slowly so that the level on the
dipstick is accurate.
Figure #18A – ZF6H
3.3.2 Changing Engine Oil
1) Operate the engine until it is warm.
2) Stop the engine. Remove the sump drain
plug and drain the lubricating oil from the
sump. Fit the drain plug tighten the plug to
34 Nm (25.1lbf-ft) /3.5 kgf-m.
3) Fill engine with oil at the oil filler neck on
the valve cover. Check that the oil is at the
‘FULL” mark on the dipstick with new and
clean lubricating oil of an approved grade.
(see Figure 19D)
Figure #19D
4) Return the unit back into service by returning
the main pump controller selector to
“automatic”.
5) Dispose used oil properly.
3.3.3 Changing Oil Filter Cartridge
1) Turn engine off.
2) Put a tray under the filter to retain spilt
lubricating oil.
Figure 14 - ZF6H
3) Remove the filter with a strap wrench or
similar tool. Then dispose of the filter
properly (Ref Figure #14).
4) Clean the filter head.
5) Lubricate the top of the filter seal with clean
engine lubricating oil.
6) Fit the new filter and tighten it until sealing
face is against the 0-ring. Turn 3/4 – 1 turns
further with the filter strap wrench.
7) Ensure that there is lubricating oil in the
sump. On turbocharged engines, ensure that
the engine will not start and operate the
starter motor until oil pressure is obtained.
8) Refer to alarm 5 of section 3.5.5 for over
crank/start disable instructions. Operate the
engine and check for leakage from the filter.
