CRANKSHAFT END PLAY • Measure the clearance between thrust bearings and crankshaft arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
• If the measured value exceeds the limit, replace thrust bearings, and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE • Measure the side clearance between connecting rod and crank- shaft arm with a feeler gauge (A).
• If the measured value exceeds the limit, replace connecting rod, and measure again. If it still exc eeds the standard, replace crank-
shaft also.
