FAQ

Q1: Is this bearing set a direct replacement for my Sumitomo SH200-3 excavator?
Yes, this SC250-2 bearing set is a direct replacement for the main and connecting rod bearings in the Isuzu 6BG1 engine, which powers the Sumitomo SH200-3 and SH300-5. However, we recommend checking your engine serial number and the condition of your crankshaft before installation to ensure it is within standard size specifications.

Q2: What material are these bearings made of, and how does it affect performance?
These bearings are made from a tri-metal material (steel backing with a bronze-lead overlay). This design provides excellent load-bearing capacity, fatigue resistance, and conformability. It allows the bearing to embed small debris and maintain a consistent oil film, significantly extending the life of your engine under heavy-duty conditions.

Q3: What should I check before installing new main and rod bearings?
Before installation, you must check the crankshaft journal for wear, out-of-roundness, and taper. If the crankshaft has been reground, you will need oversized bearings (e.g., 0.25mm or 0.50mm). Also, ensure the bearing housing is clean and free of debris. Always lubricate the bearing surfaces with clean engine oil during assembly and torque the bolts to the manufacturer’s specifications using a torque wrench.
