Description
Overview:
This valve stem cap is a genuine Villiers part for the BSA 320CC industrial engine. It sits over the end of the valve stem to provide a robust contact surface and help keep contaminants away from the valve train. Built from durable metal for long service life, it supports correct valve operation and helps maintain stable clearances under industrial use. Suitable for owners and maintainers of stationary and plant engines, it is ideal for keeping a BSA 320CC running reliably or for completing a period-correct restoration. As unused old stock, it may show light cosmetic ageing such as tarnish, but it remains functionally unused and fit for purpose. A straightforward like-for-like replacement, it keeps maintenance simple and preserves original specification.
Key Features:
- Genuine Villiers part for assured compatibility with BSA 320CC engines
- Durable metal construction designed for industrial duty
- Helps protect the valve stem end and contact surface from wear
- Aids in keeping debris away from the valve area for smoother running
- Stable fit to support consistent valve operation and clearances
- Suitable for maintenance and full restorations of vintage machinery
- Unused old stock (NOS): functional, with possible cosmetic ageing only
- Simple, direct replacement with no modifications required
Typical Applications:
Used during routine servicing, top-end repairs, and engine rebuilds on BSA 320CC industrial engines. Helps extend valve train life in generators, pumps, compressors, and other fixed or mobile plant using the BSA 320CC. Also useful for restoration projects where maintaining original specification and appearance is important.
