Connecting Rod Bearing: Testing and Inspection
INSPECTION
Crank Pin and Connecting Rod Bearings
^
Inspect crank-pin for uneven wear or damage. Measure crank pin for out-of-round or taper with a micrometer. If crank pin is damaged, or
out-of-round or taper is out of limit, replace crankshaft or regrind crank pin to undersize and use undersize bearing.
Connecting Rod Bearing Size:
Standard Diameter: 43.982 - 44.000 mm (1.7316- 1.7322 inch)
0.25 mm (0.0098 inch) Diameter: 43.732 - 43.750 mm (1.7218- 1.7224 inch)
Out-of-Round And Taper Limit: 0.01 mm (0.0004 inch)

Rod bearing:
Inspect bearing shells for signs of fusion, pitting, burn or flaking and observe contact pattern. Bearing shells found in defective condition must be
replaced. Two kinds of rod bearing are available; standard size bearing and 0.25 mm undersize bearing. To distinguish them, 0.25 mm undersize
bearing has the stamped number (US025) on its backside as indicated in figure, but standard size one has no number.
Rod Bearing Clearance
1. Before checking bearing clearance, clean bearing and crank pin.
2. Install bearing in connecting rod and bearing cap.
3. Place a piece of gauging plastic the full width of crankpin as contacted by bearing (parallel to crankshaft), avoiding oil hole.
