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
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 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
