Description
Overview:
The Valve Tappet for JAP 4/3 Engines (MPN 16491) is a genuine JAP component for classic JAP 3 and JAP 4 petrol stationary engines. A tappet sits between the camshaft and the valve gear to transfer motion reliably and maintain correct valve timing and clearance. Built from hardened steel to resist wear and scoring under continuous contact with the cam lobe, it helps preserve the cam and valve faces during long service. This unused old-stock part may show light storage tarnish but is fully serviceable. Replacing tired tappets reduces valve-train noise, prevents accelerated cam wear, and keeps engines running smoothly and efficiently. Ideal for restoration and upkeep of vintage engines used across construction, agricultural, and garden machinery.
Key Features:
- Genuine JAP part (MPN 16491) for assured compatibility on JAP 3 and JAP 4 engines
- Hardened, precision-ground steel for durability and stable clearances
- Direct replacement for the original tappet; no modifications required
- Unused old stock; may show minor cosmetic tarnish from storage only
- Recommended to replace in pairs for balanced wear and performance
- Helps protect cam lobes and valves by ensuring correct contact and motion

Typical Applications:
Used during engine rebuilds or servicing to replace worn or pitted tappets on vintage JAP petrol engines. Common on machinery powered by JAP units, such as older cement mixers, generators, compressors, pumps, and garden equipment. Helps restore smooth operation, reduce valve-train noise, and extend engine life.
