  5. To determine the correct crankshaft journal letter class, each cylinder block seat diameter letter class must be matched with the crankshaft main journal diameter letter class. Both letter classes stamped on the cylinder block as well as on the crankshaft weight are in a progressive order starting from the front of the engine. The first letter corresponds to the first cylinder, the second to the second, etc. Use the crankshaft bearing selection chart to determine the half shell color. Refer to STANDARD PROCEDURE .
  6. Select the correct and install top half of the crankshaft bearings (1) and the top half of the crankshaft thrust bearing (3) into engine block (4).
  7. Using the bearing selection chart from step five, select the correct bearing and install lower half of the crankshaft bearings (1) and the lower half of the crankshaft thrust bearing (3) into bed plate.
