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: Crank pin diameter
Standard: 43.982 - 44.000 mm (1.7316 - 1.7322 inch)
0.25 mm (0.0098 inch) undersize: 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 (US0 25) on its backside as indicated in image, 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 gaging plastic the full width of crank- pin as contacted by bearing (parallel to crankshaft), avoiding oil hole.
4. Install rod bearing cap to connecting rod.
When installing cap, be sure to point arrow mark on cap to crankshaft pulley side, as shown in image. After applying engine oil to rod bolts,
tighten cap nuts to specified torque. DO NOT turn crankshaft with gaging plastic installed.
