What is the difference between standard and undersize bearings?

Standard size bearings are meant for crankshaft journals that are still within their original factory specifications. Undersize bearings are used when the crankshaft journals have been machined down to correct for wear or damage, requiring a slightly smaller bearing to maintain the correct clearance.

Do these bearings come with installation instructions?

While these bearings are designed as direct replacements, it is always recommended to refer to the manufacturer's official service manual for your specific vehicle for detailed installation procedures and torque specifications.

What else might I need when replacing main bearings?

When replacing main bearings, it's crucial to have your crankshaft journals measured and inspected by a machine shop. You'll also need assembly lubricant to coat the bearings before installation and potentially new main bearing cap bolts.

Product Details

Already rebuilt the engine or just getting started on a refresh? This standard size main bearing set from ACL is a solid option for your 1990-1998 Hyundai Sonata with the V6 2972cc 6G72 engine. Main bearings are critical for keeping your crankshaft supported and spinning smoothly within the engine block. When you're replacing them, using a well-built set like these ensures proper clearances and long-term reliability.

ACL has been making engine bearings for a long time, and these are made to meet the original equipment specifications for your Sonata. They're built to handle the normal stresses of daily driving and keep your engine running right. Since these are standard size, they're intended for use when your crankshaft journals are still within their original factory dimensions, meaning no machining is needed for the journals themselves.

When you're doing an engine rebuild, it's always a good idea to have your crankshaft measured by a machine shop to confirm the condition of the journals and ensure you're ordering the correct bearing size. If your journals are worn beyond standard size, you'll need an undersize bearing set.
