Description
Overview:
This Genuine Honda tappet cover (OEM 12375 887 000) is a durable protective plate for the tappet chamber on Honda small petrol engines. Made from cast aluminium alloy with a corrosion-resistant natural finish, it seals the tappet area to help retain oil and keep out dust, grit, and moisture. Proper sealing protects internal components and supports stable valve train operation, promoting engine longevity and smooth running. Designed for direct fit on Honda G150 and G150K1 engines used in construction equipment and garden machinery, it matches the original form and mounting points for a straightforward replacement. A clean, undamaged cover helps maintain correct lubrication paths and reduces the risk of premature wear in engines that work hard in outdoor environments.

Typical Applications:
Used on Honda G150-series engines commonly found in cement mixers, plate compactors, generators, water pumps, pressure washers, rotavators, and other light plant and garden machinery. Ideal when refurbishing engines exposed to dust, mud, and weather, or when addressing oil leaks and contamination issues around the tappet area. Suitable for preventative maintenance to keep equipment reliable on site or in the workshop.
