Description
Overview:
This Tappet/Valve Follower is a genuine Villiers component (MPN EM520) for MK10 and MK12 engines. Precision-machined from durable, hardened steel, it sits between the camshaft and valve train to transfer motion cleanly, keeping valve timing and clearances stable. By reducing face wear and maintaining consistent lift, it helps preserve compression, starting performance and smooth running. It is suitable for Villiers-powered construction and garden machinery, where engines operate for long periods under load. Supplied as unused old stock, it may show minor storage tarnish that does not affect function. Built to original specification for a precise fit and reliable service life, it is an essential replacement when the existing tappet is worn, pitted, or out of tolerance.
Key Features:
- Genuine Villiers part for assured compatibility and reliability (OEM MPN EM520)
- Hardened steel body with a precision-ground contact face for long wear life
- Correct geometry to maintain valve lift, timing, and stable clearances
- Direct replacement for the original part in MK10 and MK12 engines
- Helps restore compression, cold starting, and consistent idle
- Robust construction for frequent starts, stop-start cycles, and extended running
- Supports proper valve train alignment to reduce noise and premature wear
- Suitable for service and rebuilds on vintage Villiers engines
- Unused old stock; cosmetic ageing from storage may be present only
Typical Applications:
Used during engine maintenance or rebuilds to replace a worn tappet in Villiers MK-series stationary engines found in construction and garden equipment. Typical duties include driving valves in machinery such as small mixers, rotavators, mowers, pumps, and generators, where stable valve timing, reliable starting, and consistent performance are required.
Also known as:
Valve lifter, cam follower, tappet lifter, valve tappet, cam lifter, valve train follower. These terms refer to the same component that transmits camshaft motion to open and close the engine's valves while controlling wear and timing accuracy.
