      Tech Tips


      • To select the correct crankshaft bearing size, calculate the crankshaft bearing number by adding together the numbers imprinted on the cylinder block sub-assembly and crank journal.

      • Example:

        Imprinted number on the cylinder block sub-assembly is 3.

        Imprinted number on the crank journal is 4.

        3 + 4 = 7

        Select a crankshaft bearing number 3.
