The 132-4762 Pin & 149-5733 Retainer assembly is a precision‑engineered fastening solution designed specifically for Caterpillar J225‑series excavators, ensuring rock-solid performance under the most demanding digging conditions.
Crafted from premium 40Cr low-alloy steel and subjected to rigorous heat-treatment, this pin-and-retainer combo delivers exceptional tensile strength and long-term wear resistance, even in abrasive
Key Benefits:
• Manufactured to Caterpillar's exacting tolerances, the 132-4762 Pin & 149-5733 Retainer integrates seamlessly with the J225 adapter and tip.
• Universal left and right hand pin design allows installation from either side, reducing operator error and speeding up changeovers.
Superior Wear Resistance
J225 Heavy Duty Pins are chamfered on both ends and have no grooves. Recommended for J225 tips and adapters and can be installed from either side of the tooth
Effortless Maintenance & Rapid Replacement
• Pin locks securely yet removes easily with standard tools, minimizing excavator idle time.
• Universal compatibility with multiple J-series models (J200 through J300) for streamlined parts inventory.
Manufacturing Process
Material Selection: Begins with high-grade 40Cr low-alloy steel billets chosen for their balance of ductility and fatigue strength.
1. Precision Forging & Heat Treatment
• Drop-forged under controlled temperatures to refine grain structure and maximize mechanical properties.
• Quenched and tempered to achieve an exact hardness profile, ensuring both impact resistance and wear life.
2. CNC Machining & Quality Control
• Computer aided design (CAD) data guides multi axis CNC turning and drilling to meet tight dimensional tolerances.
• In house metallurgical testing and non destructive inspections verify hardness, microstructure, and dimensional accuracy.
Surface Treatment Process
Shot Blasting
• All parts are blast cleaned to remove scale and prepare a uniform surface profile for coatings.
Corrosion Protection
• Black Oxide Finish: Provides a sleek, low friction surface with moderate rust resistance.
• Zinc Plating: Delivers robust corrosion protection in harsh, wet, or marine environments.
Final Passivation
• A light oil or dry film lubricant is applied to further guard against corrosion during storage and transport.
Machining Procedure
- Turning: Raw forged blanks are turned on CNC lathes to achieve precise overall length and diameter per Caterpillar spec.
- Drilling & Reaming: Pin retention holes are drilled and reamed to ensure a perfect interference fit with the retainer.
- Milling: Chamfers and reliefs are machined to facilitate smooth tooth engagement and ease of installation.
- Grinding & Polishing: Critical bearing surfaces are ground to tight surface‑finish tolerances, reducing friction and wear.
- Inspection & Packaging: Each pin retainer set undergoes final dimensional checks, hardness tests, and is individually bag‑packed to maintain cleanliness until installation.
