CONNECTING ROD SIDE CLEARANCE
^ Measure the side clearance between connecting rod and crankshaft arm with a feeler gauge.
Standard: 0.20 - 0.35 mm (0.008 - 0.014 inch)
Limit: 0.40 mm (0.016 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 (0.006 inch) per 100 mm (3.94 inch) length
Torsion:
Limit: 0.30 mm (0.012 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 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° 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.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
