Connecting Rod, Engine

CONNECTING ROD SIDE CLEARANCE





^ Measure the side clearance between connecting rod and crankshaft arm with feeler gauge.
Standard 0.20 - 0.35 mm (0.0079 - 0.0138 inch)
Limit 0.40 mm (0.0157 inch)
^ If the measured value exceeds the limit, replace connecting rod, and measure again. If it still exceeds the limit, replace crankshaft also.

CONNECTING ROD BEND AND TORSION





^ Check with connecting rod aligner.
Bend:
Limit 0.15 mm (0.0059 inch) per 100 mm (3.94 inch) length
Torsion:
Limit 0.30 mm (0.0118 inch) per 100 mm (3.94 inch) length
^ If it exceeds the limit, replace connecting rod assembly.

Rod Bearing Cap
Tighten connecting rod bolt as follows:
Apply engine oil to the threads and seats of connecting rod bolts.
Tighten bolts.
Torque 18.6 - 20.6 Nm (1.9 - 2.1 kg-m, 14 - 15 ft. lbs.)





Then tighten all bolts 90 to 95 degrees clockwise [target: 90 degrees (Angle tightening)].

CAUTION: Always use angle wrench [SST: KV10112100 (BT8653-A)]. Avoid tightening based on visual check alone.

After tightening bolt, make sure that crankshaft rotates smoothly.
Check the connecting rod side clearance.

CONNECTING ROD BOLT OUTER DIAMETER (FOR A/T MODELS)

CAUTION: Do not reuse connecting rod bolt for M/T models. Replace it with a new one.





^ Measure the outer diameter d at position shown in the figure.
^ If reduction appears in a position other than d, regard it as d.
Standard 7.90 - 8.00 mm (0.3110 - 0.3150 inch)
Limit 7.75 mm (0.3051 inch)
^ When d exceeds the limit (when it becomes thinner), replace bolt with new one.
