Caterpillar 085-9678 Shim – Precision Engineered for Excavator Performance and Durability

The Caterpillar 085-9678 Shim is a critical component designed to ensure optimal alignment and spacing within the drivetrain and structural assemblies of a wide range of Caterpillar excavators. Compatible with numerous models including the 320B, 320C series (such as 6CR-320B L, BGB-320C FM, and SAH-320C FM), 312B, 318C, and 450 series, this shim is manufactured to OEM-grade specifications. Constructed from high-strength alloy steel with precise thickness tolerances, it provides exceptional wear resistance and dimensional stability under heavy load conditions. Typical dimensions and thicknesses are engineered to exact Caterpillar standards, ensuring seamless integration and reliable performance in demanding excavation environments.

Technically, the 085-9678 Shim plays a vital role in maintaining proper clearances and load distribution within the excavator’s mechanical assemblies, reducing metal-to-metal contact and preventing premature wear. Its metallurgy is optimized for high fatigue resistance and corrosion protection, contributing to extended service intervals and reduced maintenance costs. By preserving drivetrain alignment and structural integrity, this shim enhances machine efficiency and operational uptime. Ideal for use in models ranging from the 9LJ-311-A to the MAC-320C excavators, it supports critical load-bearing points and contributes to smooth, vibration-free operation even under extreme working conditions.
