Technical Specifications and Performance Details

The 4-3960CPA connecting rod bearing set features precise housing bore dimensions, with a maximum diameter of 2.2054 inches and a minimum of 2.2046 inches, ensuring a tight and accurate fit within the engine block. The oil clearance is carefully controlled between 0.0010 and 0.0034 inches, which is critical for maintaining proper lubrication and reducing friction between the connecting rod and crankshaft. The overall length of the bearing is 0.8600 inches, providing adequate surface area for load distribution. Additionally, the wall thickness of up to 0.0587 inches contributes to durability and resistance to wear under operating conditions.

Applications and Problem Solving

This engine connecting rod bearing set is specifically engineered for use in Toyota 4Runner, Celica, Corona, and Pickup models. It addresses common engine issues such as:

• Excessive bearing wear causing knocking noises
• Improper oil clearance leading to lubrication failure
• Reduced engine performance due to bearing deformation
• Vibration and imbalance from worn connecting rod bearings
• Engine overheating caused by increased friction

Installation Notes and Tips

When installing the Sealed Power 4-3960CPA bearing set, ensure the housing bore dimensions match the specified range for optimal fit. Verify oil clearance using plastigage or a similar measuring tool to confirm it falls within the 0.0010 to 0.0034 inch range. Clean all mating surfaces thoroughly before installation to prevent contamination. Proper torque specifications should be followed to avoid bearing distortion. It is recommended to inspect the crankshaft journal for wear or damage prior to installation.
