FAQ
Q1: Are these bearings standard size or undersized/oversized? These bearings are manufactured to OEM standard size specifications (green size). They are suitable for engines with standard crankshaft journals that have not been reground. For engines that have been machined to undersize or oversize specifications, different bearing grades would be required. Always measure your crankshaft journals and connecting rod bores before ordering.
Q2: What is the proper installation procedure for these bearings? Installation requires careful attention to cleanliness and torque specifications. Ensure bearing surfaces and housing bores are clean and dry. Apply a thin film of clean engine oil to bearing surfaces before installation. Torque main bearing caps and connecting rod caps to Caterpillar C15 factory specifications (typically 95-105 ft-lbs for main bearing bolts and 55-65 ft-lbs for rod bolts). Always use a torque wrench and follow the correct tightening sequence. After installation, verify crankshaft rotation is smooth and free.
Q3: How do I verify these bearings will fit my specific C15 engine? Check your engine’s serial number plate and current bearing part numbers. The 4W-5492 and 224-3246 are standard-size bearings for most C15 engines. However, Caterpillar used different bearing grades (standard, 0.25mm undersize, 0.50mm undersize) depending on engine condition. Remove one main bearing cap and one rod cap to inspect the existing bearing markings. If your engine has been previously rebuilt, it may already have undersize bearings installed. Contact us with your engine serial number for confirmation if needed.
