Engine, description
D3.4D Engine
The D3.4D configuration is a four stroke, straight four cylinder, direct injected, water cooled diesel engine.
The engine produces powerful performance using direct injection type combustion chamber.
The valve mechanism receives its movement from the camshaft via rods and rocker arms. Turning direction is counter-
clockwise seen from the flywheel. Firing order is 1-3-4-2 and the first cylinder is on the flywheel side.
The lubrication system consists of forced lubrication with trochoid pump.
The cooling of the engine is performed by a high capacity radiator and a hydraulic oil cooler.

Precautions 200 Service Information 2014/3/30
Profile:
CEX, EW60C [GB]
Precautions
Make preparation as follows before starting engine inspection and service.
WARNING
Risk of personal injury. Very heavy object.
Be sure to fix the engine securely to prevent injury or damage due to parts falling during the work.
WARNING
Risk of personal injury! Wear safety glasses and use protective gloves.
Always wear glasses or a protective face shield when using compressed air or steam to prevent any foreign matter
from getting into the eyes.
Fix the engine on a horizontal base.
Remove the coolant hoses, fuel oil pipes, wire harness, control wires etc. connecting the driven machine and
engine, and drain coolant, lubricating oil and fuel.
Remove soil, oil, dust, etc. from the engine by washing with solvent, air, steam, etc. Carefully operate so as not to let
any foreign matter enter the engine.
Any part which is found defective as a result of inspection or any part whose measured value does not satisfy the
standard or limit shall be replaced.
Any part predicted to dissatisfy the standard or limit before the next service as estimated from the state of use
should be replaced even when the measured value then satisfies the standard or limit.

Service points
Point 1
Disassembly :
Loosen the mounting screw while supporting the alternator.
NOTE!
Do not tilt the alternator towards the cylinder block in a haste since it may damage the alternator or pinch a finger.
Reassembly:

Carefully prevent the belt from being smeared with oil or grease.
Point 2
Reassembly :
Check the thermostat function.
Point 3
Reassemble :
Replace the fuel filter element with a new one.
Disassemble :
Cover the fuel pipe opening with tape to prevent intrusion of foreign matters.
Point 4
Reassemble :
Replace the oil filter with a new one.
After fully tightening the filter manually, retighten it with a filter wrench by 3/4 turn.
Point 5
Disassemble :
Cover the fuel injection pipe and pump inlets and outlets with tape or the like to prevent intrusion of foreign
matter.
Point 6
Disassemble :
Keep the removed push rods by attaching tags showing corresponding cylinder numbers.
Reassemble :
Always apply oil to the contact portions of the push rods and valve clearance adjusting screws.
Point 7
18. Disassemble :
Loosen the cylinder head screws in two steps in the illustrated order.
Figure 3
Head screw disassembly order
1. Fan side
Place the cylinder head assembly on cardboard to prevent any damage to the combustion face.
Reassemble :
Replace the head gasket with a new one.
Figure 4
Head screw tightening order
1. Fan side
Uniformly install the head screws manually after applying oil on the threads and seat portions.
They shall be tightened in two steps in the reverse of the order for disassembly.
Tightening torque :
First step : 5 ~ 6 kgf·m (36.1 ~ 43.3 lbf·ft)
Second step : 10.5 ~ 11.5 kgf·m (75.8 ~ 83.0 lbf·ft)
Point 8
Disassemble :
Carefully remove the fuel injection valve so as not to leave the tip end protector from being left inside the cylinder.
Reassemble :
Replace the fuel injection valve protector with a new one.
Point 9
Disassemble :
When removing each inlet/exhaust valve from the cylinder head, use a valve spring compressor and compress the
valve spring and remove the valve cotter.
Figure 5
Valve spring compressor
19.
Keep each removed inlet/exhaust valve after attaching a tag showing the corresponding cylinder number.
If cotter burr is seen at the shaft of each inlet/exhaust valve stem, remove it with an oilstone and extract the valve
from the cylinder head.
Reassemble :
Replace the stem seal with a new one when an intake/exhaust valve is disassembled.
Carefully install each valve after oil application so as not to damage the stem seal.
Different stem seals are provided for the intake and exhaust valves. Do not confuse them since those for exhaust
valves are marked with yellow paint.
After assembling the intake/exhaust valve, stem seal, valve spring, seat, and cotter, tap the head of the valve stem
lightly for settling.
Do not forget to install the valve cap.
