• Helps keep your engine and crankshaft working together effectively to move your vehicle


• Can reduce friction within your engine’s piston and crankshaft connection points

As your engine runs and creates power, that force pushes the pistons back and forth. In order for that piston power to generate a rotational force that rolls your wheels forward or back, the crankshaft has to connect with the pistons. That’s where the engine connecting rod is key.

On one end of the connecting rod, you'll find the Engine Connecting Rod Bearing. The Engine Connecting Rod Bearing is a small circular piece that reduces friction and encourages fluid rotary force for your connecting rods at their insertion points on the crankshaft. Your Engine Connecting Rod Bearing is only one tiny part of the crankshaft assembly, but it's important for your engine's efficiency.

Since your INFINITI connecting rods are subject to an extremely repetitive motion, a faulty or worn Engine Connecting Rod Bearing might lead to a misshapen cylinder or diminished engine efficiency. In extreme cases, a cracked, damaged, or warped rod bearing can cause your rod to snap, causing permanent damage to your crankshaft (which is, in most cases, not able to be repaired and will debilitate your engine permanently).

Replacing your INFINITI Engine Connecting Rod Bearing, part number 12111JK20A, calls for extensive knowledge and significant labor. Therefore, it’s best to get help from the pros at your nearby INFINITI dealer or authorized service site for the task.
