Description

Overview:
The Crankshaft Gear for Villiers MK25 3:1 Reduction Box (EM406) is a genuine Villiers drive gear used within the reduction gearbox on classic Villiers engines. Made from steel, it transfers power from the crankshaft into the 3:1 reduction train to deliver smooth, dependable drive to the output shaft. Built to original Villiers specification, it suits MK25 and MK20 engines equipped with the factory 3:1 reduction box. This is unused old stock from the period, so minor tarnish or storage marks may be present, but it remains unfitted and serviceable. Choose this gear when you need correct fit, authentic build quality, and reliable performance during repairs, servicing, or restoration of machinery powered by these well-known Villiers units.

Key Features:
- Genuine Villiers part for assured fit and compatibility with the 3:1 reduction box
- Steel construction for strength and long service life in demanding use
- Accurate tooth form to help ensure smooth meshing and consistent power transmission
- Maintains the correct 3:1 reduction for proper torque and output speed
- Like-for-like replacement to simplify fitting with original hardware
- Suitable for restoration projects where authenticity matters
- Unused old stock: cosmetic tarnish may be present but does not affect function
- Helps reduce drivetrain chatter and wear when paired with a sound reduction box
- Manufactured to the original Villiers design tolerances
- Reliable choice for ongoing maintenance of classic plant and garden machinery

Typical Applications:
Used in the 3:1 reduction gearbox on Villiers MK20 and MK25 engines found on classic garden and light construction equipment. Common on rotavators and cultivators, lawn mowers, small cement mixers, generators, water pumps, and other compact plant where controlled output speed and higher torque are required.
