Trusted by operators in more than 60 countries, the Shacman WP12 Oil Filter Group is a global benchmark for heavy‑duty oil filtration reliability. Its proven design and robust construction make it a cornerstone of modern commercial vehicle lubrication systems.
The oil filter seat is precision‑cast from high‑strength aluminum alloy with a corrosion‑resistant coating, featuring integrated oil passages, bypass valve, and mounting flanges. Its robust design ensures secure attachment and leak‑free operation.
The filter element uses high‑efficiency synthetic or cellulose media with a precisely calibrated micron rating, effectively capturing particles as small as 5‑10 microns while maintaining low flow restriction. Its pleated design provides a large surface area for extended service life.
The filter group includes a bypass valve that opens when the filter becomes clogged, ensuring that oil continues to flow to the engine, preventing oil starvation. This safety feature is critical for maintaining lubrication under extreme conditions.
The assembly is supplied with all necessary seals and O‑rings, ensuring a complete, hassle‑free replacement. Installation is straightforward, with detailed torque specifications provided for accurate assembly.
This oil filter group is an essential maintenance component for any WP12 engine, offering improved oil cleanliness, reduced wear, and extended component life. Its genuine Shacman quality ensures that your engine continues to deliver reliable performance.
Oil Filter Seat – The main housing that mounts the oil filter element to the engine block, directing oil flow through the filter media. Precision‑cast from high‑strength aluminum alloy with a corrosion‑resistant coating, this seat features integrated inlet and outlet galleries, a bypass valve, and a mounting flange. Its internal passages are engineered to minimize pressure drop while ensuring full flow through the filter element. The seat includes a threaded center stud or bolt for securing the filter canister, and a sealing surface that accommodates an O‑ring or gasket. The bypass valve is calibrated to open at a predetermined pressure (typically 2‑3 bar), allowing oil to bypass a clogged filter to maintain engine lubrication. The seat is designed to withstand high oil pressures (up to 10 bar) and temperatures, providing a reliable, leak‑free connection. This oil filter seat is a direct replacement for the original factory component, ensuring identical flow characteristics and durability. Its robust construction and precise machining guarantee a perfect fit and long‑term reliability, making it a critical component of the WP12 lubrication system.
Filter Element – The consumable filtration media that captures contaminants from the engine oil, ensuring clean oil reaches all critical components. Manufactured from high‑efficiency synthetic or cellulose fibres with a precisely controlled micron rating (typically 10‑15 µm absolute), this element features a pleated design that maximizes surface area while minimising flow restriction. The media is resin‑impregnated for strength and resistance to oil degradation, and it is supported by a perforated steel core and end caps. The element includes a bypass valve (optional) and anti‑drain back valve to prevent oil from draining out when the engine is off, ensuring immediate oil pressure on start‑up. Its high dirt‑holding capacity extends service intervals and reduces the frequency of replacements. This filter element is engineered to meet or exceed original equipment performance standards, effectively removing soot, wear metals, and sludge. Regular replacement with genuine Shacman elements is essential for maintaining oil cleanliness and extending engine life. This element is supplied as a complete unit, ready for installation into the filter seat.
