2.1 Removing Crankshaft
1. Remove the oil sump and the suction pipe.
2. Disconnect the balancing unit lubricating oil pipe from the cylinder block and unscrew the balancing unit fixing bolts. Remove the balancing unit and the lubricating oil pipe (only 44-engines).
3. Remove the flywheel and the crankshaft oil seal with the housing.
4. Remove the speed sensors and the timing gear cover. (see instruction 5.1. ).
5. Remove the connecting rod bearing caps and push the connecting rods out of the way of the crankshaft.
6. Remove the main bearing caps and lift out the crankshaft.
2.2 Checking Crankshaft
1. Clean the crankshaft. Do not forget the oil ways.
2. Measure the journal wear in several points. Out-of-round, taper or other wear must not exceed 0.03 mm.
3. Refit the bearing caps with new bearing shells and tighten them to the correct torque. Measure the I.D. with a dial gauge which has been zeroed to the dimensions given in point 2. With this method the indicator shows the actual bearing clearance. Measure at several points in case the worn bearing housing is not round.
4. Maximum allowed bearing clearance is 0.18 mm for main bearings or 0.14 mm for connecting rod big-end bearings with new bearing shells.
2.3 Changing Crankshaft Gear
1. Break the crankshaft gear using e.g. a grinder. Grind the gear sufficiently.
Hit the gear apart with a chisel. Do not damage the crankshaft!
2. Clean the seat on the crankshaft, for example, with a wire brush.
3. Install key pins to crankshaft (if removed). Use one drop of Loctite 603 or equivalent to ensure adhesion.
4. Heat the new gear to 190'Ct.1 O'C .
5. Tap the gear onto the shaft with drift 9103 94700. Ensure that the aligning marks on the gear are visible. No clearance is allowed between gear surface and crankshaft surface (arrowed).
6. Let the gear cool without using any coolant.
