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.

Built to original Villiers specification, it suits MK25 and MK20 engines equipped with the factory 3:1 reduction box.
