Connecting Rod
WARNING: This page is about a different variant/trim than selected.
- Replace the connecting rod, if the large or small end thrust surface is damaged.
- Check for bend or twist using a connecting rod aligner. Replace the connecting rod if the bend or twist exceeds the limit.
Limit of bend or twist per 100 mm (3.9370 in) in length:
0.10 mm (0.0039 in)
- Install the connecting rod with bearings attached to the crankshaft, and using a thickness gauge, measure the thrust clearance. If the thrust clearance exceeds the standard or uneven wear is found, replace the connecting rod.
Connecting rod thrust clearance:
Standard
0.070 - 0.330 mm (0.0028 - 0.0130 in)
- Inspect the connecting rod bearing for scar, peeling, seizure, melting, wear, etc.
- Measure the oil clearance on each connecting rod bearing using plastigauge. If any oil clearance is not within the standard, replace the defective bearing with a new part of standard size or undersize as necessary.
Connecting rod oil clearance:
Standard
0.017 - 0.045 mm (0.0007 - 0.0018 in)
Unit: mm (in) Bearing Bearing size (Thickness at center) Outer diameter of crank pin Standard 1.490 - 1.506 (0.0587 - 0.0593) 51.976 - 52.000 (2.0463 - 2.0472) 0.03 (0.0012) Undersize 1.504 - 1.512 (0.0592 - 0.0595) 51.954 - 51.970 (2.0454 - 2.0461) 0.05 (0.0020) Undersize 1.514 - 1.522 (0.0596 - 0.0599) 51.934 - 51.950 (2.0447 - 2.0453) 0.25 (0.0098) Undersize 1.614 - 1.622 (0.0635 - 0.0639) 51.734 - 51.750 (2.0368 - 2.0374) - Inspect the bushing at connecting rod small end, and replace the connecting rod if it is worn or damaged.
- Measure the piston pin clearance at connecting rod small end. If the measured value is not within the standard, replace the connecting rod and piston pin as a set.
Clearance between piston pin and bushing:
Standard
0 - 0.022 mm (0 - 0.0009 in)
