10. Check the TDC marking of OT on the crankshaft.8. Install the chain tensioner.
Tightening Torque 80 Nm
Notice
Replace the seal.
Before installation, by pumping in the oil approx. 10 times,
fill the oil.
9. Remove the engine lock.
Notice
If max. length ‘L’ of the 12-sided bolt exceeds 53.6mm,
replace it.

In this position, the marking on camshaft / camshaft bearing
cap (arrow) must also be aligned. If the markings are not
aligned, the timing chain must be re-set and the injection
pump timing has to be set.
14. Position the no.1 cylinder at TDC.
11. Place the fitting tool (8) onto the chain link and rivet the
chain pins one by one.
12. Check the riveting of chain pins and re-rivet if necessary.
13. Remove the wire.
Tightening Torque 35 - 40 Nm

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
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.
