What is the difference between standard and undersize bearings?

Standard (STD) bearings are used when the crankshaft journals are at their original factory size. Undersize bearings are needed if the crankshaft has been machined (ground down) to remove wear or damage. This set is standard size.

What else might I need when installing these bearings?

When installing connecting rod bearings, it's critical to have the correct assembly lubricant to coat the bearings before installation. You'll also need to follow the manufacturer's specific torque sequence and values for the connecting rod bolts.

How do I know if I need to replace my connecting rod bearings?

Symptoms of worn connecting rod bearings often include a knocking or rattling sound from the engine, especially under load or at idle. Low oil pressure can also be an indicator. It's best to replace them during any engine rebuild or if you suspect internal engine damage.

About this part

Product Details

You get a full set of connecting rod bearings in this kit, which means one box handles the whole engine rebuild or repair. These bearings are crucial for your engine's health. They sit between the connecting rod and the crankshaft, allowing the rod to spin smoothly while handling the immense forces generated during combustion. Without good bearings, you'll quickly see metal-on-metal contact, leading to catastrophic engine failure.

ACL has been making engine bearings for a long time, and this set is built to meet the original specifications for your Mazda 4-cylinder engine. They're made from a strong, multi-layer material designed to hold oil and reduce friction, keeping your engine running cool and preventing premature wear. This is a standard size (STD) set, meaning it's meant to be used when the crankshaft journals are still within their original factory tolerances. If your engine has been rebuilt before and the crankshaft has been machined, you might need an undersize bearing set.

When you're rebuilding an engine, it's important to replace all the wear items. This set is a solid option for your Mazda B2200, 626, or MX-6. Make sure to clean all engine components thoroughly before installation and follow the manufacturer's lubrication and torque specifications to ensure a long life for your new bearings.
