Description
Overview:
The Cover for Tappets EM486 is a genuine Villiers metal cover that seals and protects the tappet chest on classic side‐valve engines. It keeps dirt and debris out of the valve gear while helping retain oil where it is needed, supporting smoother running and reduced wear. Built to original specifications for a precise fit on Villiers MK20 and MK25 engines, it is suitable for use on many small plant, garden, and light industrial machines powered by these engines. As unused old stock, it may show minor age‐related marks from storage but remains unused and serviceable. This is an OEM component designed for straightforward replacement during routine servicing, repairs, or full restorations where authenticity and reliable performance are important.
Key Features:
- Genuine Villiers part (OEM) for assured compatibility and quality
- Correct fit for the tappet chest on MK20/MK25 engines for reliable sealing
- Sturdy metal construction for long service life under workshop and site conditions
- Helps prevent ingress of dirt and grit, reducing tappet and cam follower wear
- Supports proper lubrication of the valve train by enclosing the tappet area
- Unused old stock vintage item; may show light storage marks, function unaffected
- Simple to install during routine maintenance or engine rebuilds
- Matches original appearance for authentic restorations
- Suitable for use with an appropriate gasket to maintain oil tightness (gasket not included unless specified)
- Stable under normal engine operating temperatures and vibrations
Typical Applications:
Ideal for maintaining or restoring Villiers‐powered equipment such as small plant, pumps, generators, lawn and garden machinery, and light construction tools. Use when replacing a damaged, corroded, or missing tappet cover, or during overhaul to ensure the valve gear remains protected from contaminants and retains oil for reliable operation.
