FAQ

Q1: Is this bearing set a direct replacement for the OEM Yuchai parts?

Yes, this set is manufactured to OEM size and specifications, specifically for the YC6B120-T20 engine with part number BB7F0B0005. It is designed as a direct, drop-in replacement. We always recommend comparing the part number and engine model with your original part to ensure a perfect match.

Q2: What is the difference between Standard and Oversize bearings? Which one do I need?

This listing is for a Standard Size (OEM Size) bearing set. Standard bearings are used when the crankshaft journals are within factory tolerances. Oversize bearings (e.g., 0.25mm, 0.50mm) are required if the crankshaft has been ground down during a rebuild. You must measure your crankshaft journals with a micrometer or consult your engine manual to determine if standard or oversize bearings are needed for your specific application.

Q3: What maintenance checks should be performed during installation?

Before installation, ensure the bearing shells and their housing bores are perfectly clean and free of debris. Lubricate the bearing surfaces with clean engine oil during assembly. Always check the bearing clearance using Plastigage to confirm it is within the engine manufacturer’s specifications. Proper torque of the main bearing cap and connecting rod cap bolts is critical; always use a calibrated torque wrench and follow the specified tightening sequence and angle.
