Connecting Rod, Engine

CONNECTING ROD SIDE CLEARANCE





^ Measure the side clearance between connecting rod and crankshaft arm with a 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 a 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.

CONNECTING ROD BOLT OUTER DIAMETER





^ Measure the outer diameter d at position shown in the figure.
^ If the 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 connecting rod bolt with new one.

Rod Bearing Cap
Tighten connecting rod bolt as follows:
Inspect the outer diameter of connecting rod bolt.
Apply engine oil to the threads and seats of connecting rod bolts.
Tighten connecting rod bolts.
Torque 19.6 Nm (2.0 kg-m, 14 ft. lbs.)





Then tighten all connecting rod bolts 90 degrees clockwise (Angle tightening).

CAUTION: Always use the angle wrench [SST: KV10112100 (BT8653A)]. Avoid tightening based on visual check alone.

After tightening connecting rod bolts, make sure that crankshaft rotates smoothly.
