FAQ

Q1: Is this bearing set the correct size for a standard crankshaft?
A: No. This set is specifically a 0.25mm oversize. It is designed for use with a crankshaft that has been reground to the 0.25mm undersize. If your crankshaft is standard (not ground), you must use standard-size bearings. Please confirm your crankshaft journal size before ordering.

Q2: What is the proper installation procedure for these bearings?
A: Installation requires a clean environment. Ensure the bearing saddles and caps are perfectly clean and dry. Apply a thin film of clean engine oil to the bearing surface. Do not use grease. Install the bearings without mixing the halves. Tighten the main bearing and connecting rod cap bolts to the manufacturer’s specified torque settings using a calibrated torque wrench. Always follow the engine service manual.

Q3: How can I verify the quality of these aftermarket bearings compared to OEM?
A: Our bearings are manufactured to meet OEM performance standards. You can verify the quality by checking the part number cross-reference against your original Weichai bearings. The material appearance (aluminum-tin layer) and precise machining are key indicators. For critical applications, we recommend measuring the oil clearance using Plastigage during assembly to confirm correct fitment.
