The 8D4812/8D-4812 shim is a precision-machined component designed for cylinder head adjustment in CAT G3508, G3512, and G3516 gas engines. It ensures proper clearance between the cylinder head and valve train, critical for maintaining engine compression and preventing premature wear. The part number 8D4812 corresponds to a specific thickness variant within the CAT shim series, engineered to meet OEM tolerances for gas engine applications.
Shims in this series are typically manufactured from high-carbon steel or alloy steel, heat-treated to achieve a hardness of 50-60 HRC for durability under high-stress conditions. Typical industry standards for gas engine shims include a surface flatness of 0.005 mm and thickness tolerances of ±0.01 mm, ensuring consistent performance in high-precision assemblies. The material composition and heat treatment process are selected to resist deformation and corrosion in gas engine environments.
These shims are primarily used by OEMs, engine rebuilders, and industrial maintenance teams servicing CAT gas engines in power generation, oil and gas, and marine applications. Buyers often source them in bulk to support scheduled maintenance or emergency repairs, with packaging typically including 10-50 pieces per set to match common service intervals. Confirm compatibility with the specific engine model and cylinder head kit, as CAT gas and diesel variants may require different shim specifications.

Before ordering, verify the exact part number compatibility with your CAT G3508, G3512, or G3516 gas engine model, as shim thickness and material can vary by production year and engine configuration. Request a cross-reference chart from Wuhan Weyeah Power Machinery to match the 8D4812 shim to your cylinder head kit, as using an incorrect thickness can lead to valve train misalignment or premature wear.
Confirm logistics details such as lead time, which may range from 7 to 30 days depending on stock availability and production schedules. Clarify Incoterms (e.g., FOB Wuhan or CIF your port) and payment terms, as these are not specified in the listing. For bulk orders, negotiate packaging options to ensure shims are protected from corrosion and physical damage during transit, especially for sea freight.
Quality checks should include dimensional verification of thickness, flatness, and hardness using calibrated tools. Request a material test report and surface finish certification to ensure the shims meet OEM and industry standards. For critical applications, consider third-party inspection in China before shipment, focusing on the shim’s geometric tolerances and material composition to avoid costly engine failures.
