What is the difference between standard and undersize bearings?

Standard size bearings are meant to be used when the crankshaft journals are still within factory specifications. Undersize bearings are used when the crankshaft has been machined down (ground) to remove damage or wear, requiring a bearing with a slightly smaller inner diameter to maintain proper clearance.

Do these bearings come with a warranty?

ACL typically offers a warranty on their engine bearings. Please refer to the manufacturer's documentation or contact customer support for specific warranty details and coverage.

What else might I need when installing main bearings?

When installing main bearings, it's essential to have a clean work environment, proper torque wrenches for the main caps, and assembly lube to lubricate the bearings and journals during initial startup.
