Alternator Drive Coupling Tool Kit

Part Number: 08-17440

Overview

This tool kit supports the inspection, installation, and removal of alternator drive couplings on several Continental piston engine series. It includes a spanner wrench and a coupling gear socket built to protect the steel coupling gear during service work. The coupling itself acts as a shear point that protects the engine if the alternator fails, so periodic inspection is required to catch wear or improper installation before it causes engine damage. Using dedicated tools like this kit helps avoid misdiagnosing coupling slippage as an alternator failure.
