Detailed Description

Sealed Power 4500AA is engineered for engine rebuild and repair work where accurate bearing dimensions matter. The bearing’s standard-size design and controlled oil clearance help maintain the proper interface between the connecting rod and crankshaft journal, while the listed housing bore and shaft dimensions support correct fitment during assembly. Sealed Power uses modern materials and ISO- and QS-certified manufacturing processes to produce engine parts that meet demanding service requirements.

This part cross-references Monroe Shocks & Struts (e.g., CB1667A, CB1667P) for the same application. It is a practical choice for technicians and DIY rebuilders working on Ford F-150, Ford Mustang, or Mercury Cougar engines that call for this bearing specification.

What It Helps Address

• Excessive connecting rod bearing wear
• Low oil pressure caused by bearing clearance issues
• Rod knock from worn bearing surfaces
• Engine noise related to bottom-end clearance problems
• Restoration work on worn A-Series aluminum engine assemblies

Installation Notes and Tips

• Verify crankshaft journal size and housing bore before assembly.
• Measure oil clearance during installation to confirm it stays within specification.
• Inspect rods and journals for scoring, taper, or out-of-round conditions before reuse.
• Clean all mating surfaces thoroughly before final assembly.
• Confirm the engine uses the correct A-Series aluminum application before ordering.
