( Brand: Caterpillar ), ( Manufacturer Part Number: 9R8709 ), ( Part Type: Pin )
The Caterpillar 9R8709 pin is an essential component of Caterpillar hydraulic excavators, specifically those in the 320, 323, and 330 series. This industrial-grade pin is designed to provide superior strength, durability, and reliability for heavy-duty applications.
Measuring at approximately 2.3 inches (58.4mm) long and 1 inch (25.4mm) in diameter at its larger end, this round, tapered pin is engineered using high-quality steel. Its tapered design ensures smooth and consistent movement of the excavator's buckets and other hydraulic components. The pin's smaller end measures just under 0.8 inches (20.3mm) in diameter.
The surface of the pin is treated with Robbins & Myers Full Depth Quench and Temper process to provide increased strength while reducing the risk of cracking during heavy loading conditions. This treatment not only enhances the pin's resistance to wear and tear but also ensures that it can maintain its shape and integrity under extreme conditions.
The Caterpillar 9R8709 pin features a fine finish, ensuring a good connection between mating parts and minimizing any unwanted friction. It is also designed to withstand high temperatures, which makes it suitable for use in various climates and operating environments.
Ready for immediate use in your Caterpillar machinery, this replacement pin is precisely engineered to match the dimensions and mechanical properties of the original equipment manufacturer (OEM) pin. It is supplied individually for ease of replacement and ensures the continued high performance and productivity of your Caterpillar hydraulic excavator. In the event you require a matching cotter pin to secure this pin in place, please consider purchasing a Caterpillar part number 3BB08730 or equivalent replacement.
