Our 8E6358 (9J2358) and 8E6359 (3G9549) bucket pins & retainers are specially designed for Caterpillar J350 series excavators. They are made of high-quality 40Cr alloy, precision forged, CNC machined and customized surface treated, with a hardness of up to HRC48-52 and excellent wear resistance and corrosion resistance.
8E6358 & 8E6359's Overview
1. Part Numbers: 8E6358 (9J2358) Pin & 8E6359 (3G9549) Retainer
2. Compatibility: Fits Caterpillar J350/J450 bucket teeth (e.g. 1U3352, T1U3352L, 1U3352WTL) for backhoes, loaders, skid steers, graders, scrapers, and excavators.
3. Material: High-grade 40Cr alloy steel for superior tensile strength and impact toughness.
8E6358 & 8E6359's Advantages
1. Exceptional Durability
Wear Resistance: Core hardness HRC 48-52 after controlled heat treatment extends service life under abrasive conditions.
Secure Locking: Retainer geometry precisely matches OEM profiles, preventing tooth slippage under shock loads.
2. Precision Fit & Reliability
Tight Tolerances: CNC machining to tight tolerances ensures minimal play and easy installation, reducing bucket vibration and premature wear.
Corrosion Protection: Choice of blackening, zinc plating, or plain finish guards against rust and friction, ideal for harsh environments.
Manufacturing & Machining Process
1. Blank Preparation: Starting from 40Cr ingots, blanks are produced via sand casting or forging to optimize grain flow for strength.
2. Rough Machining: Forged blanks undergo CNC roughing to remove excess material, then pre-heat inspection.
3. Heat Treatment: Precisely controlled quench-and-tempering cycles achieve the target HRC 48-52 hardness for balanced toughness and wear resistance
4. Finish Machining: High-precision CNC milling and turning, deliver consistent interchangeability and form accuracy
5. Surface Treatment & QC: Final surface finish (blackening/zinc plating) is applied, followed by dimensional, hardness, and visual inspections
