Removal Procedure
1. Pull out the tensioning lever (19) together with the spring
(17) and guide rail (16) far enough until the tensioning lever
has passed the oil pump chain (9) and is resting against
the crankshaft (13).
2. Pull out tensioning lever (19), spring (17) and bushing (18)
from the bearing pin (6).
3. Pull out the guide rail (16).
4. Remove the bolt(11) and then remove the washer (10), oil
pump chin (9) and sprocket (8).

Installation Procedure
1. Put the same alignment mark on the new crankshaft
sprocket as in the old sprocket.
Notice
Check the timing chain, camshaft sprocket, injection pump
timing sprocket, oil pump chain and oil pump sprocket for
wear and replace if necessary.
2. Install the new crankshaft sprocket (12) by using a drift (21).
Notice
Align the groove of sprocket and woodruff key (arrow)
exactly.
Drift 116 589 07 15 00
3. Fit the timing chain (4) on the crankshaft sprocket (12).
Notice
Align the alignment marks (arrow) on the chain and sprocket.
4. Install the camshaft sprocket (3).
Tightening Torque 25 Nm + 90°
Notice
Pay attention on the alignment marks and dowel pin (arrow).

Notice
If the max. length ‘L’ of the stretch bolt exceeds 53.6mm,
replace it.
5. Fit the oil pump chain (9) on the crankshaft sprocket (12)
and insert the oil pump sprocket (8) into the oil pump chain
and then install it on the oil pump.
Notice
The curved side of the oil pump sprocket should face the
oil pump.
6. Insert the woodruff key (15).
7. Install the guide rail (16). Attach the spring (17) to guide rail
and to tensioning lever together onto the bearing pins (5,6).
Notice
Ensure that the spring is correctly located in the guide rail
(arrow).

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.

6. Coat the cylinder bore, connecting rod bearing journal,
connecting rod bearing shell and piston with oil.
7. Compress the piston rings with a tensioning strap (7).
Tensioning Strap 000 589 04 14 00
8. Insert the piston assembly into the cylinder with a wooden
stick (18).
Notice
The arrow on the piston crown must point toward the front
of vehicle.
9. Insert the connecting rod bearing shells (9, 10).
Notice
Be careful of the difference in upper and lower bearing
shells and not to be changed.
10. Position the connecting rod bearings caps.
Notice
Position so that the retaining lugs are on the same side of
the connecting rod bearing(arrow).
11. Measure stretch shaft diameter (C) of the connecting rod
bolts.
Limit ‘C’ 7.1mm

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.
