•The crankshaft main journals should be checked for
excessive wear, roundness and scoring. Limits of
roundness on any crankshaft main journals should
be held to 0.008 mm. Limits of roundness on any
crankshaft rod journals should be held to 0.005
mm. DO NOT nick crank pin or bearing fillets. Lim-
its of out of round on any crankshaft journals
should be held to 0.005 mm.
• Check the axial clearance after installation. Stan-
dard of axial clearance should be 0.07 mm. Limits
of axial clearance should be held to 0.265 mm.
• Clean the journal and bearing.
• Install the crankshaft.
• Cut the plastic-gauge to the same width as the
bearing, and then put it onto the crankshaft journal
to make it parallel with the central line of the crank-
shaft.
• Install the main bearing cap carefully, and tighten
the bolts to the specified torque.
• Remove the main bearing cap.
• Measure the oil clearance with the plastic-gauge.
Standard oil clearance of crankshaft rod and
main journals should be 0.022 mm
Limits of oil clearance of crankshaft rod and main journals should be 0.058 mm
Standard oil clearance of crankshaft main journal
should be 0.022 mm. Limits of oil clearance of crank-
shaft main journal should be 0.058 mm.
