Crankshaft: Specifications
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
