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.

CONNECTING ROD BUSHING OIL CLEARANCE
Connecting Rod Bushing Inner Diameter





Measure the inner diameter of connecting rod bushing with inside micrometer.
Standard 22.000 - 22.012 mm (0.8661 - 0.8666 inch)

CONNECTING ROD BOLT OUTER DIAMETER





^ 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.

Rod Bearing Cap
Tighten connecting rod bolt as follows:
Apply engine oil to the threads and seats of connecting rod bolts.
Tighten bolts.
Tightening 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. Refer to "CONNECTING ROD SIDE CLEARANCE".
