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,

Notice
Always install the chain tensioner to be filled with oil.
Place the chain tensioner in engine oil up to over the collar on the hexagon head with the thrust pin facing up.
Slowly push down the thrust pin as far as the stop 7~10 times with the aid of a press or a column drill
Faulty chain tensioners should be replaced completely.

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.

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.

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
