Connecting Rod: Specifications

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:
Inspect outer diameter of connecting rod bolt. (A/T models).

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

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° clockwise [target: 90° (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.

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.
