Connecting Rod Bearing (Big End) - Inner Diameter

Connecting Rod Bearing (Big end)
1. Install connecting rod bearing to connecting rod and cap.
2. Install connecting rod cap to connecting rod.
Tighten bolts to the specified torque.






3. Measure inner diameter "C" of each bearing.






4. Measure outer diameter "Dp" of corresponding crankshaft pin journal.
5. Calculate connecting rod bearing clearance.

Connecting rod bearing clearance = C - Dp
Standard: 0.020 - 0.045 mm (0.0008 - 0.0018 inch)
Limit: 0.065 mm (0.0026 inch)

If it exceeds the limit, replace bearing.
If clearance cannot be adjusted within the standard of any bearing, grind crankshaft journal and use undersized bearing.









If crankshaft is replaced with a new one, select connecting rod bearing according to the table.
