Description
Overview:
The Connecting Rod Small End Bush for the BSA 420 cc Industrial Engine (OEM 66 492) is a genuine Villiers component designed to restore accurate running clearances at the little end of the con-rod. This solid, precision‐machined bronze bush provides a stable, low‐friction bearing surface for the gudgeon (piston) pin, helping to maintain correct alignment between the piston and connecting rod under load and at operating temperature. It is engineered specifically for the BSA 420 cc Industrial Engine, often used in stationary equipment for construction, agriculture, and workshop power. Supplied as unused new old stock, the bush may show light tarnish consistent with age, but it remains unused and serviceable. Correct fitment and lubrication support dependable engine performance and reduced wear.
