Layshaft to fit on 3:1 Reduction Box on Villiers MK20 & C25 – EM404

Description

The layshaft is a genuine Villiers component for the 3:1 reduction boused on vintage Villiers MK20 and C25 engines. Precision‐machined from hardened steel for strength and dimensional stability, it supports the reduction gear train and maintains accurate alignment between mating gears and bearings. This preserves smooth, efficient power transfer from the engine to the output, helping the transmission run quietly and reliably. As unused old stock, the part is authentic and may show light tarnishing from storage without affecting performance. Ideal for restoring or maintaining older garden and construction machinery powered by these engines, it provides the correct fit and specification expected of OEM parts for long service life.

Key Features:
– Genuine Villiers part for assured compatibility with 3:1 reduction boxes
– OEM tolerances for correct gear alignment and smooth power delivery
– Hardened steel construction resists wear, pitting, and deformation under load
– Unused old stock (NOS); may exhibit minor tarnish that does not affect use
– Designed for reliable engagement with reduction gears and bearings
– Supports quiet running and consistent output speed reduction (3:1)
– Suitable for refurbishment of vintage machinery using MK-series engines
– Straightforward replacement when refurbishing transmissions or curing play and noise
– Robust, long‐life design appropriate for regular use in workshop or site conditions

Typical Applications:
Used in the 3:1 reduction boon Villiers engines commonly found in vintage mowers, rotavators, pumps, generators, compact mixers, and other small plant. Fit this shaft during a gearborebuild to restore correct clearances, reduce backlash, and improve drive smoothness. It is well suited to preservation restorations and routine maintenance on working equipment where authenticity and durability are important.

Also known as:
Countershaft, intermediate shaft, secondary shaft, reduction boshaft, layshaft gear, power transmission spindle. These terms describe the same function: a central shaft that carries gears within the reduction stage to transmit and control drive from the engine to the output.
