Technical Specifications and Performance Details

The 4-3910RA connecting rod bearing set from Sealed Power is engineered to meet strict dimensional tolerances critical for engine reliability. The housing bore max and min dimensions ensure a precise fit within the engine block, minimizing unwanted movement. Oil clearance specifications between 0.0010 and 0.0030 inches provide the necessary lubrication gap to reduce friction and wear during engine operation. The overall length and shaft diameter measurements are optimized for the connecting rods used in Ford Aspire, Ford Festiva, and Mazda Protege engines, ensuring compatibility and performance. Additionally, the wall thickness of 0.0594 inches contributes to the bearing's structural integrity under high-stress conditions.

Applications and Problem Solving

  • Replaces worn or damaged connecting rod bearings in Ford Aspire, Ford Festiva, and Mazda Protege engines
  • Addresses engine knocking caused by excessive bearing clearance
  • Prevents premature bearing wear due to improper oil clearance
  • Helps restore proper engine oil pressure and lubrication
  • Reduces risk of connecting rod damage from bearing failure

Installation Notes and Tips

When installing the Sealed Power 4-3910RA bearing set, ensure the engine block and connecting rods are thoroughly cleaned to remove debris and old lubricant. Verify the housing bore dimensions and oil clearance with precision measuring tools to confirm compatibility. Proper torque specifications should be followed when securing the connecting rods to avoid distortion. It is recommended to replace bearings in matched sets to maintain balanced engine performance.
