FAQ

Q1: How do I confirm that this bearing set fits my Xinchai XC490BPG engine?
A: This bearing set is specifically manufactured for the Xinchai XC490BPG diesel engine model. Before purchasing, please verify your engine’s model number (located on the engine nameplate) and check that your crankshaft requires standard (STD) size bearings. If your engine has been previously rebuilt with oversized bearings, or if the crankshaft has been reground, you may need undersized or oversized bearings. We recommend consulting your engine service manual or contacting our technical support with your engine serial number for confirmation.

Q2: What is the difference between main bearings and connecting rod bearings in this set?
A: Main bearings support the crankshaft within the engine block and are typically larger, while connecting rod bearings fit between the connecting rod and crankshaft journal. This set includes both types, specifically sized for the XC490BPG engine. The main bearings provide stable crankshaft rotation, while the connecting rod bearings handle the reciprocating forces from the pistons. Both are equally critical for engine performance and longevity. Installation requires proper torque specifications and lubrication procedures as outlined in the engine service manual.

Q3: What maintenance practices help extend the life of these bearings after installation?
A: To maximize bearing life, follow these practices: (1) Use the correct viscosity and quality of engine oil as specified by Xinchai; (2) Maintain proper oil pressure and change oil and filters at recommended intervals; (3) Avoid engine overheating by ensuring the cooling system functions correctly; (4) Perform regular oil analysis to detect early signs of bearing wear or contamination; (5) During installation, ensure all bearing surfaces are clean and properly lubricated, and tighten bolts to manufacturer torque specifications. Proper break-in procedures after a rebuild are also essential for long bearing life.
