Detailed Description

Sealed Power 4135RA is engineered as a standard-size connecting rod bearing for engines that require accurate bearing geometry and controlled oil clearance. The listed dimensions help match the rod journal and housing bore specifications found in compatible Ford, Mazda, and Mercury A-Series aluminum engine builds. This part number, 4135RA, is used across multiple model years including Ford Focus, Ford Escape, Ford Escort, Mercury Cougar, Ford Contour, Mercury Mystique, and Mazda Tribute.

Sealed Power parts are manufactured with modern materials and ISO- and QS-certified processes to support consistent quality in engine service work. If you are replacing worn rod bearings during an engine rebuild or bottom-end repair, 4135RA provides the dimensional accuracy needed for proper fitment in the specified applications.

This part cross-references Ford OE-style numbers such as F5RZ6211A and F8CZ6211AA for the same application.

What It Is Used For

• Replacing worn or scored connecting rod bearings
• Restoring correct rod bearing clearance after engine wear
• Addressing low oil pressure concerns related to bearing wear
• Reducing rod knock caused by excessive bearing clearance
• Supporting engine rebuilds on compatible Ford, Mazda, and Mercury vehicles

Installation Notes and Tips

Verify rod journal diameter, housing bore, and oil clearance before assembly. Clean all mating surfaces thoroughly, use proper engine assembly lubricant, and confirm bearing orientation during installation. Measure clearances with the crankshaft and connecting rods in serviceable condition, and follow the engine manufacturer’s torque and rebuild specifications.

Quality Assurance

Sealed Power uses leading-edge materials and ISO- and QS-certified manufacturing processes to produce engine bearings that meet the demands of modern engines. Confirm fitment by engine code and bearing dimensions before installation.
