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 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 BIG END DIAMETER





^ Install connecting rod bearing cap without installing connecting rod bearing, and tighten connecting rod bolts to the specified torque. Refer to "ASSEMBLY" for the tightening procedure.
^ Measure the inner diameter of connecting rod big end with an inside micrometer.
Standard 55.000 - 55.013 mm (2.1654 - 2.1659 inch)
^ If out of the standard, replace connecting rod assembly.

CONNECTING ROD BUSHING OIL CLEARANCE
Connecting Rod Bushing Inner Diameter





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

Piston Pin Outer Diameter





Measure the outer diameter of piston pin with a micrometer.
Standard 21.989 - 22.001 mm (0.8657 - 0.8662 inch)

Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) - (Piston pin outer diameter)
Standard 0.005 - 0.017 mm (0.0002 - 0.0007 inch)
Limit 0.030 mm (0.0012 inch)
^ If the calculated value exceeds the limit, replace connecting rod assembly and/or piston and piston pin assembly.
^ If replacing piston and piston pin assembly, refer to "HOW TO SELECT PISTON".





^ If replacing connecting rod assembly, refer to "CONNECTING ROD BEARING OIL CLEARANCE" to select the connecting rod bearing.

Factory installed parts grading:








^ Service parts apply only to grade "0".





CONNECTING ROD

CONNECTING ROD CAP





Match the stamped cylinder number marks on connecting rod with those on connecting rod cap to install.
Tighten the connecting rod nuts as follows:
Apply engine oil to the threads and seats of the connecting rod bolts and nuts.
Tighten connecting rod nuts.
Tightening Torque 14.7 Nm (1.5 kg-m, 11 ft. lbs.)
Put mating (with paint) on each nut and connecting rod cap, all in the same direction (when using a protractor).
