CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while mov-
ing the connecting rod back and forth.
Standard thrust clearance:
0.15 - 0.30 mm (0.0059 - 0.0118 in.)
Maximum thrust clearance: 0.35 mm (0.0138 in.)
If the thrust clearance is greater than maximum, replace the
connecting rod assembly(s). If necessary, replace the crank-
