Notice There are two kinds of connecting rods (for machining) and they are different in weight approx. 15g. When replacing the connecting rod, measure its weight and ensure that a engine has the same weight of connecting rods. If not, there would be a unbalancing of engine.

1B3-166 OM600 ENGINE MECHANICAL Installation Procedure
1. Fit the piston onto the connecting rod so that the arrow(15) and the locking slot (16) are facing in direction of the vehicle.
2. Coat the piston pin (15) with engine oil and insert it by hand. Notice Do not heat up the piston.
3. Install the new snap ring (4) into the grooves (arrow).
4. Check the piston rings (1, 2, 3) and replace them if necessary.
5. Install and arrange the piston rings to be evenly 120 ° from
each ends gap.

12. Coat the bolts (12) with oil and then tighten the bolts.
Tightening Torque40Nm + 90°
13. Rotate the crankshaft and check axial clearance between the connecting rod and crankshaft.
14. Measure clearance between the piston crown and cylinder
Standard Max. 0.12mm
15. Position the piston at TDC and measure the distance between the piston crown and the crankcase surface.
Notice Measure at points marked. Dial Gauge 001 589 00 53 21
Dial Gauge Holder 363 589 02 21 00
Standard Max. 0.965 mm

Measurement Procedure
1. Measure height ‘A’ .
Limit 142.5 mm
Notice If the height is less than 142.5mm, replace the cylinder head.
2. Insert the valve (1) and measure valve arrears ‘a’.
Valve Arrears ‘a’ 0.1 - 0.7 mm
Notice If out of standard, machine the valve seat.
3. Install the prechamber and measure protrusion ‘C’.
Protrusion ‘C’ 7.6 - 8.1mm
4. Assemble the engine and check the valve timing.

Tools Required 102 589 00 15 00 Drift 102 589 12 15 00 Drift Replacement Procedure
1. Completely drain the coolant.
2. Remove any parts which impede access.(Example : transmission, injection pump)
3. Place the screwdriver to the deepdrawn edge of the core plug and pull forward and then rotate 90 °.
4. Pull out the core plug with pliers.
5. Thoroughly clean the sealing surface and apply Loctite 241.
6. Install the new core plug by using a drift. Drift 102 589 00 15 00 (F34) Drift 102 589 12 15 00 (F17)
7. Install the removed parts and fill the coolant. Notice The adhesive must be allowed to harden for about 45 minutes before filling of coolant.
8. Warm up the engine and check the coolant for leaks.

Removal & Installation Procedure
1. Remove the timing case cover.
2. By inserting a round bar (6) approx. 0.7m from the back tothe front side through the oil gallery, knock out the steel balls (1,3). Notice Be careful not to damage the bores of the steel balls.
6 Shop-made tool
3. Thoroughly clean the bores of steel balls.
4. Place the steel ball (3) onto the drift (7) with a little grease and position to the bore and then tap until the drift stops.

3. Connect the special tool to the reservoir filler cap and apply 1.4 bar of pressure.
SYSTEM LEAKAGE TEST
Tools Required
124 589 15 21 00 Tester Test Procedure
1. Loosen the cap a little and release pressure and removethe cap. NoticeFor the risk of scalding, cap must not be opened unless the coolant temperature is below 90 °C.
2. Fill coolant up to upper edge (arrow) of reservoir.
Tester 124 589 15 21 00
4. If the pressure on the tester drops, check leakage at the all coolant hoses and pipes and each connections. Replace or retighten if necessary.

6. Remove the de-aeration hose clamp in the coolant pumpand remove the de-aeration hose.
7. Fill up the coolant through the coolant reservoir tank. Notice
Match the anti-freeze and the water ratio to 50 : 50.
Supplement the coolant until the coolant overflows to the deaeration hose.
8. Insert the de-aeration hose and completely tighten the clamp.
9. Check the coolant level in the coolant reservoir tank.
10. Warm up(until thermostat is opened) the engine and recheck the coolant level in the reservoir tank and fill upthe coolant if necessary.
