Information:
start by:a) remove flywheel housingb) remove valve liftersc) remove pistonsd) remove timing gear cover and oil pump1. Fasten a hoist and put the engine in position on tool (A).2. Turn the crankshaft until the timing mark on the crankshaft gear is in alignment with the timing mark on the camshaft gear. For more detail about removal of main bearings see REMOVE AND INSTALL CRANKSHAFT MAIN BEARINGS. 3. Remove bolts (1) and main bearing caps (2). Remove the lower halves of the main bearings from the caps.4. Install two of the bolts that hold the flywheel in place in the end of crankshaft. 5. Fasten a hoist and remove crankshaft (3) from the engine. The weight of the crankshaft is 54 kg (120 lb.).
Be careful not to cause damage to the crankshaft journals when the crankshaft is removed.
6. Remove the upper halves of the main bearings from the cylinder block.7. Install tooling (B) and remove the gear from the crankshaft. Install Crankshaft And Gear
1. Install the key for the crankshaft gear so it is even with the end of the crankshaft.2. Heat the crankshaft gear to a maximum temperature of 260°C (500°F). Install the gear on the crankshaft with the timing mark on the gear toward the pulley end of the crankshaft.3. Install the thrust bearing for the No. 4 main. Install the bearings dry when the clearance checks are made. Put clean engine oil on the bearings for final assembly.4. Install the upper main bearings (the bearings with oil hole) into the engine block.5. Install two of the bolts that hold the flywheel in place in the end of the crankshaft. Fasten a hoist and put the crankshaft in position in the block. Make sure the timing mark on the crankshaft gear is in alignment with the timing mark on the camshaft gear. For more detail about installation of main bearings see REMOVE AND INSTALL CRANKSHAFT MAIN BEARINGS.
When the bearing caps are installed, make sure the number on the side of the cap is next to and respective with the number on the engine block.
When the bearing clearance is checked and the engine is in a vertical position, the crankshaft will have to be lifted up with a force equal to the weight of the crankshaft and held against the upper halves of the main bearings to get a correct measurement with Plastigage. The Plastigage will not hold the weight of the crankshaft and give a correct indication. If the engine is in a horizontal position, such as on an engine stand, it is not necessary to hold the crankshaft up. Do not turn crankshaft when Plastigage is in position to check clearance. 6. Check the bearing clearance with Plastigage. Put the lower main bearings into the caps. Put the caps in position and install the bolts. Tighten the bolts in number sequence as follows: a) Tighten bolts 1 through 10 to a torque of 40 4 N m (30 3 lb.ft.).
Do not use an impact
