658714 – Continental Motors OEM Connecting Rod Bushing

Available now on the Airparts.aero Marketplace.

Overview

The Continental Motors 658714 is a genuine OEM connecting rod bushing, also known as a piston pin bushing, engineered for a specific range of geared and high-performance Continental aircraft engines. This component is precision-machined to serve as the critical bearing surface between the piston pin and the small end of the connecting rod. Fabricated from a specialized, high-performance bronze alloy, the 658714 is designed to endure the unique load characteristics and higher operational stresses found in geared powerplants. As a genuine Continental OEM part, it guarantees the precise material composition, dimensions, and quality required for a reliable, airworthy engine overhaul.

Key Features

• Application-Specific Alloy: Manufactured from a high-strength bronze alloy specifically selected by Continental to handle the unique stress and wear profiles of geared engines, providing superior performance and fatigue resistance.
• Precision Interference Fit: The bushing's outer diameter is machined to exacting tolerances to create the required interference fit when pressed into the connecting rod, ensuring it remains fixed under all operational loads.
• Machinable Inner Diameter: Supplied with a semi-finished inner bore. This is a critical design feature that necessitates final honing or reaming after installation to achieve the precise, specified clearance with the piston pin, ensuring proper lubrication and load distribution.
• Superior Lubricity: The bronze material is inherently porous, allowing it to retain oil and maintain a critical hydrodynamic film between the bushing and the oscillating piston pin, preventing metal-to-metal contact.
• Genuine OEM Certification: As a factory-certified component, the 658714 meets all FAA production approval standards and conforms to the engine's original type certificate, ensuring the highest level of safety and quality.

Technical Specifications

• Part Number: 658714
• Component Type: Connecting Rod Bushing / Piston Pin Bushing
• Installation Method: Press-fit into the small end of the connecting rod.
• Final Sizing: Must be honed or reamed to final size after installation.
• Material: High-Strength, High-Performance Bearing Bronze Alloy
• Certification: FAA Production Approval

Engine Compatibility

The Continental 658714 bushing is specified for use in some of Continental's most powerful and complex geared engines. It is essential to consult the specific engine's Illustrated Parts Catalog (IPC) and overhaul manual to verify the correct part number for your application.

• Compatible Engine Series:
  • GTSIO-520 Series (Geared, Turbocharged, Supercharged, Fuel Injected)
  • Note: Applicability may extend to other specific engine models. Verification against the engine's official documentation is mandatory.

Applications

The 658714 bushing has a singular, high-stress application within the engine:

• Geared Engine Reciprocating Assembly: Serves as the pivotal bearing surface transferring force from the piston to the connecting rod in engines with a propeller speed reduction unit (PSRU) or "gearbox."
• Mandatory Overhaul Component: This bushing is a mandatory replacement item during any major engine overhaul to restore critical operational clearances and ensure the integrity of the reciprocating assembly.

Why Choose 658714?

Geared engines like the GTSIO-520 subject their internal components to different harmonic vibrations and stresses than direct-drive engines. The 658714 bushing was specifically engineered by Continental for this demanding environment. Using a genuine OEM part is the only way to guarantee that the material alloy and manufacturing process are correct for these unique loads. Substituting a non-certified part or using an incorrect part number risks bushing failure, piston pin seizure, and catastrophic engine damage. For professional engine shops specializing in these high-performance powerplants, using the genuine 658714 is a fundamental requirement for a safe and reliable overhaul.

The Continental 658714 connecting rod bushing serves as a plain bearing in one of the most punishing locations within a geared piston engine. It must withstand the immense downward force of the power stroke while also accommodating the complex oscillating motion of the connecting rod. The final machining process after installation is critical; the bore must be perfectly round and have a surface finish that is smooth enough to minimize friction but textured enough to retain an oil film under boundary lubrication conditions. The clearance between the bushing's inner diameter and the piston pin's outer diameter is typically measured in ten-thousandths of an inch and is crucial for maintaining the hydrodynamic wedge of oil that prevents metal-to-metal contact. Any deviation can lead to rapid wear and failure, underscoring the need for both a genuine 658714 part and expert installation.

Note: This is a critical engine internal component that requires specialized tools and expertise for proper installation. Installation and final sizing must be performed by a qualified engine machinist or certified A&P mechanic in strict accordance with the procedures outlined in the current Continental Motors Overhaul Manual for the GTSIO-520 or other applicable engine model.
