Note: Do not rotate the crankshaft under any circumstances when checking the clearance.
Remove any remaining oil from the main journals and cylinder block bearings.
Install the crankshaft and crankshaft thrust half rings on the 3rd support (grooves to the crankshaft cheeks).
Cut several pieces of calibrated wire.
Place the wire along the axis of the crankshaft main journals (outside the area of the lubrication holes for the supports).
Install the crankshaft main bearing caps, positioning cap 1 on the flywheel side.
Tighten the crankshaft main bearing cap bolts to the specified torque (25 Nm + 47°±5°) in the specified order and tighten to the required angle. Remove the main bearing caps and the crankshaft.
By flattening the calibrated wire (1), determine the gap between the bearing shells and the main journals using the scale (2) printed on the packaging.
Check the clearance, which should be 0.027-0.054 mm. Clean the crankshaft and main bearing shells from the remains of calibrated wire.
