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)

Piston Pin Outer Diameter





Measure the outer diameter of piston pin with 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 measured 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.
