Care of the System
The performance of the engine is dependent on ensuring that the following maintenance is carried
out as per the schedule without fail.
Accessory Belt
: To be checked and adjusted if required at every 10,000 Kms. To be replaced at every
80,000 Kms.
Air cleaner:
The element should be replaced at every 40,000 Kms or when red indicator band shows.
For the detailed procedure,
refer to the Air Intake System.
Oil:
. The oil should conform to
CH4
grade and with a viscosity Index of 15W40. It should be kept in
mind that in the turbocharger engine the oil has to have do an additional load of lubricating and
cooling the Turbocharger shaft If any oil of lower specification is used it can break down under the
high thermal load at the turbine end of the shaft especially during the hot shutdown.
This oil grade also ensures that the oil consumption is within the desire limits.
Use Maximile Supreme
Grade of oils. The Oil change intervals are first at 5000 Kms. & then subsequently every 15000 Kms.
Cooling system:
Ensure that no leakages are present. For details of the coolant and ratio refer the
Cooling System
.
Turbocharger:
The engine is having an exhaust gas driven turbocharger. The turbocharger shaft speed
varies from about 40, 000 when engine is idling to about 1,70,000 when the engine is having the full
rated RPM.
EGR:
On vehicles fitted with EGR system the following additional points check have to done during
scheduled maintenance.
•
Check for any exhaust gas leakage through sealing faces, EGR pipe. Formation of any black
soot indicates leakage.
•
Check the vacuum hoses for any leaks, cracks.
•
Retighten all nuts and bolts as per the recommend torque.
Tappet
setting has to be carried out every 20000 Kms.
While doing the tappet clearance, in case of vehicle fitted with EGR system ensure that the EGR pipe is
not bent or overstress the pipes, elbow.
If the pipes are removed then it is essential that while fitting back; new gaskets be used. Do not open
the pipe from one end only; it will cause the pipe to twist. If the EGR pipe has to be removed, then
open from both the ends.
