28. Remove the connecting rod bearing cap.
29. Install the piston.
30. Rotate the crankshaft by hand and check whether it rotatessmoothly.
31. If the bearings are damaged,
- replace the oil presser relief valve. - clean the oil pump and oil filter housing carefully and
replace the hose if necessary. Notice After assembling the engine, check the camshaft timing, adjust the start of fuel injection and check the TDC sensorbracket setting.
32. Fill oil and run the engine and then check the oil pressure and oil level. Notice Install the original oil filter element and then change the engine oil and oil filter element after 1,000 - 1,500km.
27. Measure the radial clearance (L) of the connecting rod
bearing. Example) Measured value ‘J’ = 47.700mm
Measured value ‘K’ = 47.653mm
Clearance ‘L’ = 0.047mm
Radial Clearance ‘L’0.026 - 0.068mm
Notice If the clearance is out of standard, adjust the radial clearance of connecting rod bearing by replacing theconnecting rod bearing shells.
26. Measure connecting rod bearing journal diameter (K).
Notice Refer to measurement of the crankshaft bearing journal
diameter.
24. Insert the new connecting rod bearing shells into theconnecting rod and connecting rod bearing cap and tighten
the 12-sided stretch bolts (11).
25. Measure inner diameter of connecting rod bearing.
Tightening Torque 40 Nm + 90 °

M161 ENGINE COOLING 1D2-13
Removal & Installation Procedure
1. Drain the coolant.
2. Remove the de-aeration hose (4), coolant outlet hose (5) and coolant bypass hose (6).
3. Disconnect the coolant temperature sensor connector.
4. Unscrew the bolt (1c) and pry off the tensioning device shock absorber (7).Installation Notice
6. Replace the O-ring with new one.
7. Installation should follow the removal procedure in the reverse order.
8. Check for leaks in cooling system.
5. Unscrow the bolts (1a, 1b) and remove the engine
hanger bracket and thermostat housing.Installation Notice

1. Preheating time - control relay.Control relay functions as followings :
Switching of preheating current.
Indication of preheating finish.
Control of preheating sequence.
Indication of fault.
2. Coolant temperature sensor. Coolant temperature sensor senses coolant ’s temperature
and signals it to the preheating relay continuously.
3. Glow plug The glow plug parts are housing with M12 ´ 1.25 thread
and heating pin in housing. It is connected in a parallel circuit
with the specified voltage of 11.5V. The heating element has a heating coil and a control coil and they are connected in series.
1. Control Coil 2. Heater Coil
4. Current and temperature of glow plug Current of glow plug While the preheating system operates, current of about
30A flows in each glow plug and temperature of heating coil rises very fast.
Due to the rise of temperature, the resistance of control
coil increases therefore the current is controlled to
about 8~15A and that protects the glow plug from over-
heating.
Temperature of glow plug The temperature of the glow plug reaches up to 900 °C
after about 9 seconds and up to 1,050 °C after 30
seconds.
