Description
Overview:
This Key for Timing Gear is a genuine Villiers part (MPN 18429) for classic Villiers petrol engines. It is a semi‐circular Woodruff key made from steel, used to locate and secure the timing gear on the crankshaft so the cam timing remains accurate during operation. Correct key fit prevents gear slippage, protects the keyway, and helps the engine start and run smoothly. Suitable for engine rebuilds and routine maintenance, it is an exact-match service component for vintage Villiers units such as MK10 and MK12. Supplied as unused old stock, it may show light tarnishing from age, which does not affect performance. This is part of our remaining stock of vintage Villiers spares, ideal for keeping original engines working as designed.
