What does 'undersize 0.25mm' mean for these bearings?

This means the bearings are manufactured to be 0.25mm smaller in diameter than standard size. They are designed to be used when the crankshaft journals have been machined down by 0.25mm to remove wear or damage, ensuring the correct oil clearance is achieved.

Why are crankshaft main bearings important during an engine rebuild?

Crankshaft main bearings support the crankshaft within the engine block, allowing it to rotate smoothly. They are critical for maintaining the correct oil clearance, which is essential for lubrication and preventing metal-on-metal contact, ensuring the engine's longevity.

Do these bearings come with installation instructions?

While this set includes the necessary bearings for your engine rebuild, it's always recommended to refer to the manufacturer's official service manual for detailed installation procedures and torque specifications.

Product Details

You get a full set of engine crankshaft main bearings in this kit, which means one box handles the critical components for your engine rebuild. These bearings are essential for supporting the crankshaft and ensuring it spins smoothly within the engine block. When you're rebuilding an engine, especially if the crankshaft has been machined, using the correct size bearings is crucial for proper oil clearance and engine longevity. This set is specifically sized at 0.25mm undersize, meaning it's intended for use with a crankshaft that has been ground down by 0.25mm to clean up imperfections or achieve a specific clearance.

ACL is a well-known name in engine bearings, and this set is made to meet the demands of an engine rebuild. They are built to provide the necessary support and oil flow for the crankshaft. Proper installation is key here; these bearings need to be seated correctly and the oil clearances checked meticulously to ensure the engine runs right and lasts. If you've had your crankshaft machined undersize, this is the exact set you'll need to get everything back into spec.
