Camshaft Adjuster Tool for Audi RS4, A6, A8 – 4.2L FSi 8-Cylinder

Brief Overview

This is a precision-engineered camshaft adjuster tool designed specifically for Audi's 4.2L FSi 8-cylinder engines. It enables proper engagement and tensioning of the camshaft adjuster unit during timing chain service—a critical operation for maintaining engine timing accuracy on high-performance and luxury models. When combined with a dedicated camshaft wrench for VW/Audi platforms, this tool becomes part of a complete timing system service kit.

Key Features

• Cup-shaped design with hexagonal central boss for secure socket engagement
• Three internal engagement lugs precisely positioned to locate onto OEM camshaft adjuster features
• Single-piece cast alloy construction with robust, wear-resistant finish
• Through-hole center accepts standard socket drivers for positive torque application
• Application-specific geometry eliminates guesswork and ensures proper alignment

Product Description

This camshaft adjuster tool is a purpose-built holding device that prevents camshaft rotation during timing chain adjustment procedures. The three symmetrically-spaced internal lugs grip the matching pockets of the OEM camshaft adjuster, preventing unwanted movement while torque is applied. The hexagonal boss and central through-hole allow technicians to use standard metric sockets and torque wrenches, ensuring repeatable, accurate tensioning.

The cast alloy construction provides the strength required for repeated use in professional shops without deformation. The unfinished interior surfaces and precision-cast lug geometry guarantee positive engagement with Audi FSi adjuster units, eliminating slippage and the risk of rounded features.
