Foreword
This manual deals with specific mechanical and electrical information needed by engine mechanics for troubleshooting, servicing, repairing, or overhauling the engine. Accurate measurements and adherence to specified torque values are critical for the successful reconditioning of Kohler Magnum engines. Use only genuine Kohler replacement parts to ensure quality and durability. The Automatic Compression Release (ACR) is a precision-engineered component; never attempt to bend the flyweight tab as it will break.
