OM600 ENGINE MECHANICAL 1B3-161
Installation Procedure
1. Put the same alignment mark on the new crankshaftsprocket 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).

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

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.
