What does '0.020 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.020 inches smaller in diameter than standard size. This is necessary when the crankshaft journals have been machined down by 0.020 inches during an engine rebuild to correct wear or damage.

Are these bearings sold as a complete set for the engine?

Yes, this is a set of connecting rod bearings. It is designed to cover all the connecting rods in your engine for a complete rebuild.

What is the proper oil clearance for these bearings?

Proper oil clearance is critical for engine bearing performance. Always refer to the specific service manual for your 2003-2004 INFINITI M45 and the ACL installation instructions for the exact oil clearance specifications and torque values.

Product Details

You get a full set of connecting rod bearings in this kit, which means one box handles the critical engine rebuild component. These bearings are essential for proper engine function, allowing the connecting rods to rotate smoothly within the crankshaft. For your 2003-2004 INFINITI M45 with the VK45 V8 engine, getting the right size bearings is key to a successful rebuild.

This set from ACL is specifically sized at 0.020 inches undersize. This is important if your crankshaft journals have been machined down during an engine rebuild to correct wear or damage. Using the correct undersize bearing ensures the proper oil clearance between the rod and the crank, which is vital for oil pressure and engine longevity. ACL is known for making well-built engine components, and these bearings are made to meet the demands of a V8 engine.

When rebuilding your VK45 V8, using a matched set of bearings like these from ACL is a solid choice. Make sure to follow the manufacturer's installation instructions carefully, as proper oiling and torque specifications are critical for engine bearing performance.
