Sealed Power Engine Connecting Rod Bearing Overview

The Sealed Power 4185RA engine connecting rod bearing is engineered for precise fitment and reliable performance in Saturn vehicles. Designed specifically for Saturn SC, SC1, SC2, SL, SL1, SL2, SW1, and SW2 models, this bearing ensures optimal engine operation by maintaining proper oil clearance and housing bore dimensions.

Compatible with Saturn SC, SC1, SC2, SL, SL1, SL2, SW1, and SW2 models
Housing bore diameter ranges from 1.9761 to 1.9766 inches (50.1930 to 50.2070 mm)
Oil clearance between 0.0005 and 0.0021 inches (0.0130 to 0.0530 mm) for precise lubrication
Overall length max of 0.8000 inches (20.3200 mm) for accurate fit
Wall thickness max of 0.0626 inches (1.5900 mm) for durability

Technical Specifications and Performance Details

The 4185RA connecting rod bearing from Sealed Power is manufactured to meet strict dimensional tolerances, ensuring compatibility with the standard shaft diameter of 1.8500 to 1.8508 inches (46.9900 to 47.0100 mm). The bearing's housing bore max and min dimensions provide a tight fit within the engine assembly, reducing the risk of excessive wear or engine noise. Oil clearance specifications are critical for maintaining proper lubrication film thickness, preventing metal-to-metal contact and extending engine life.

Applications and Problem Solving

This engine connecting rod bearing is designed for use in Saturn vehicles, specifically the SC, SC1, SC2, SL, SL1, SL2, SW1, and SW2 models. It addresses common engine issues such as:

Reducing bearing wear caused by improper oil clearance
Minimizing engine knocking due to bearing failure
Preventing premature engine damage from bearing surface fatigue
Ensuring smooth piston movement by maintaining correct housing bore dimensions
Supporting engine rebuilds requiring precise bearing replacements

Installation Notes and Tips

When installing the Sealed Power 4185RA connecting rod bearing, ensure the following:

Verify the bearing dimensions against the engine specifications for Saturn SC and SL series models
Check the oil clearance using plastigage or a similar tool to confirm it falls within the 0.0005 to 0.0021 inch range
Clean all mating surfaces thoroughly before installation to prevent contamination
Follow manufacturer torque specifications for connecting rod bolts
Inspect the crankshaft journal for wear or damage prior to bearing installation

Quality Assurance and Warranty

Sealed Power manufactures the 4185RA connecting rod bearing to meet industry standards for durability and precision. Each bearing undergoes rigorous quality control to ensure dimensional accuracy and material integrity. While specific warranty details are not provided, Sealed Power products typically conform to OEM quality requirements, supporting reliable engine performance in Saturn SC and SL models.
