Service Limits & General Specifications

CRANKSHAFT END PLAY





^ Move the crankshaft fully forward and backward and measure the clearance between the thrust bearings and crankshaft arm using suitable tool.
Standard: 0.10 - 0.26 mm (0.0039 - 0.0102 inches)
Limit: 0.30 mm (0.0118 inches)
^ If measured value exceeds the repair limit, replace the thrust bearings, and measure again. If it still exceeds the repair limit, replace crankshaft also.

CRANKSHAFT JOURNAL DIAMETER
^ Measure diameter of crankshaft journals.
Standard: 63.940 - 63.964 mm (2.5173 - 2.5183 inches)
^ If measurement is out of standard, measure the main bearing oil clearance. Then use the undersize bearing. Refer to "MAIN BEARING OIL CLEARANCE".

CRANKSHAFT PIN DIAMETER





^ Measure diameter of crankshaft pin using suitable tool.
Standard: 53.956 - 53.974 mm (2.1243 - 2.1250 inches)
^ If measurement is out of standard, measure the connecting rod bearing oil clearance. Then use the undersize bearing. Refer to "CONNECTING ROD BEARING OIL CLEARANCE".

OUT-OF-ROUND AND TAPER OF CRANKSHAFT





^ Measure dimensions at four different points as shown on each journal and pin.
^ Out-of-roundness is indicated by the difference in dimension between "X" and "Y" at "A" and "B".
^ Taper is indicated by the difference in dimension between "A" and "B" at "X" and "Y".
Limit
Out-of-round (Difference between X and Y): 0.002 mm (0.0001 inches)
Taper (Difference between A and B): 0.002 mm (0.0001 inches)
^ If measured value exceeds the standard, correct or replace crankshaft.
^ If corrected, measure the bearing oil clearance of the corrected journal or pin. Then select the main bearing or connecting rod bearing. Refer to "MAIN BEARING OIL CLEARANCE" or "CONNECTING ROD BEARING OIL CLEARANCE".

CRANKSHAFT RUNOUT





^ Place a V-block on a precise flat table to support the journals on both ends of the crankshaft.
^ Measure at No. 3 journal using suitable tool.
^ While rotating crankshaft, read the movement of the pointer.
^ Half of the movement shows the runout.
Limit: Less than 0.05 mm (0.002 inches)
^ If measurement exceeds the limit, replace crankshaft.
