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.

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 Torque 40Nm + 90°
13. Rotate the crankshaft and check axial clearance between
the connecting rod and crankshaft.
14. Measure clearance between the piston crown and cylinder
StandardMax. 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.

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 to
the 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.

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 remove
the cap.
Notice
For 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 pump
and remove the de-aeration hose.
7. Fill up the coolant through the coolant reservoir tank.
Notice
lMatch the anti-freeze and the water ratio to 50 : 50.
lSupplement 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 up
the coolant if necessary.
