Description
Overview:
The Valve Spring Collar (Inlet) for Villiers 444H engines is a small but critical valve-train component. Made from durable, heat‐resistant steel, it sits at the top of the inlet valve spring to keep the spring correctly located under load, helping maintain consistent valve lift, timing, and compression. This Genuine Villiers part (OEM ref. 21620/3) is a direct replacement for the original collar used on the 444H, ensuring the correct fit and geometry without modification. Supplied as unused old stock, it may show light tarnish or storage marks, but remains fully serviceable. Ideal for owners and repairers maintaining classic Villiers-powered equipment, it supports smooth running, easier starting, and reliable performance after head overhauls or routine maintenance.
Key Features:
- Genuine Part: authentic Villiers component for assured compatibility and quality
- OEM reference 21620/3 for precise fit on the 444H inlet side
- Tough steel construction to withstand spring loads and heat cycles
- Correct profile for secure seating of the inlet valve spring
- Unused old stock; may have cosmetic storage tarnish only
- Direct replacement part; straightforward to fit during head work
- Helps restore stable idle, good compression, and smooth running
- Suitable for preventative maintenance and full engine rebuilds
Typical Applications:
Used during service or overhaul of the inlet valve assembly on Villiers 444H engines found in vintage lawn mowers, cultivators, pumps, generators, and light construction machinery. Ideal when replacing worn or missing hardware, addressing valve noise, or correcting weak spring seating to improve reliability and performance in everyday and professional use.
