Description
Overview:
These valve spring bottom cups are genuine Villiers components for the Villiers BSA 65cc engine. Made from durable steel with a shallow dished profile, they sit beneath the valve spring to provide a stable, flat seating surface and maintain correct spring alignment and height. This helps reduce valve train wear, prevents spring chatter, and supports consistent engine compression and timing in vintage machinery. Supplied as unused old stock, they may show mild tarnishing from storage that does not affect performance. Ideal for restoring or maintaining classic small engines used in construction and garden equipment, and a precise OEM replacement under part number 87 41 for dependable fit and function.
Key Features:
- Genuine Villiers part for assured compatibility and quality (OEM No. 87 41)
- Steel construction for strength, stability, and long service life
- Correct seating surface helps prevent spring movement and wear
- Maintains valve spring installed height for reliable valve timing
- Suitable for vintage restorations and routine maintenance
- Unused old stock; cosmetic tarnish from storage may be present only
- Simple fitment in the cylinder head under the valve spring
- Designed to work with standard valve train components on the Villiers BSA 65cc engine
Typical Applications:
Used in the cylinder head of Villiers BSA 65cc engines to support valve springs in classic garden and light industrial machinery. Common in restoration projects, engine rebuilds, and preventative maintenance where stable valve spring seating is needed to keep engines starting easily, idling smoothly, and running reliably under regular use.
Also known as:
Valve spring seats, lower valve spring seats, valve spring bases, spring platforms, bottom spring cups, lower spring retainers (base), spring seating cups. These terms are commonly used for the same component that supports the valve spring at the head side.
