What is the purpose of the coating on these bearings?

The special coating on these ACL rod bearings helps to reduce friction and wear, particularly during the engine's break-in period. It also assists in maintaining the necessary oil film between the bearing and the crankshaft journal for smooth operation.

Why is it important that these bearings are 'No Notch'?

The 'No Notch' designation means these bearings are designed for connecting rod housings that do not have a specific slot or notch for the bearing to seat into. This ensures they fit precisely in compatible engine designs without interference.

Are these bearings suitable for a crankshaft with worn journals?

No, these are standard size bearings. They are intended for use with crankshaft journals that are within factory specifications. If your crankshaft journals are worn, you will likely need to use an undersize bearing set and have the crankshaft ground to match.

About this part

Product Details

Already rebuilding your Audi or VW inline 4-cylinder engine? This set of standard size, coated connecting rod bearings is a crucial piece of the puzzle. These bearings sit between the connecting rod and the crankshaft, allowing the rod to spin smoothly while handling the immense forces generated during combustion. Replacing them is a key step in any engine overhaul to ensure proper oil clearance and long-term reliability.

ACL has applied a special coating to these bearings, which helps to reduce friction and wear, especially during the critical break-in period. This coating also aids in maintaining the correct oil film between the bearing and the crankshaft journal. This particular set is designed for engines that do not use a locating notch on the bearing shell, ensuring a precise fit in the connecting rod housing. They are standard size, meaning they are intended for use with an unworn crankshaft journal.

This set includes the bearings for four connecting rods, suitable for most inline 4-cylinder applications. Always refer to your vehicle's specific service manual for proper installation procedures and torque specifications.
