the exhaust pipe surface temperature is very high during diesel engine working, avoid mounting
the exhaust
pipes near flammable materials so as to protect the working personnel against scald accidents.
Please install
heat insulation device on the surface of external exhaust pipe.
4. Mounting of cooling system
The coolant pipes in the diesel engine are connected before the diesel engine leaves the factory, so
mounting is not required. Adopt anticorrosion materials for coolant pipes and reduce the pipe
length and
number of elbows. The inner diameter of coolant pipe shall not be smaller than that of joint
connecting
parts, so as to reduce the water resistance and improve the water pump efficiency.
5. Precautions for mounting of diesel engine front end output
The diesel engine front end output belt pulley can be used for driving small machines such as the
water
pump and the generator and be arranged at sides of diesel engine symmetrically to protect the
diesel engine
crankshaft against one-way pulling force. If large machines (such as net hauler) need to be driven,
the
elastic couplings must be used for connecting and mount the couplings according to alignment
accuracy of
different couplings. During operation, correct the coaxial accuracy regularly to ensure coaxiality
of
couplings. Otherwise, the diesel engine parts may be damaged.
6. Refer to the aforementioned chapters when mounting other parts of the
diesel engine.

Maintenance
of
WP13C
series
diesel
engines
Correct maintenance can ensure normal and reliable operation of diesel engine, and it is important for
prolonging the service life of diesel engine. Users shall carry out diesel engine maintenance regularly
according to the technical maintenance items in this chapter.
1. Maintenance interval of WP13C series diesel engines
Initial check (P) Diesel engine running for 30~50h
Level 1 maintenance (WD1) Diesel engine running for every 250h
Level 2 maintenance (WD2) Diesel engine running for every 500h
Level 3 maintenance (WD3) Diesel engine running for every 1000h
Level 4 maintenance (WD4) Diesel engine running for every 4000h
Explanation:
The above maintenance intervals are calculated assuming that the diesel engine runs for
1500h each year. If the running time of diesel engine each year does not exceed 500h, the maintenance
intervals can be 0.5 times of the above intervals. If the running time of diesel engine each year exceeds
1500h, the maintenance intervals can be 1.5 times of the above intervals.
