Whether you are rebuilding an engine or performing routine maintenance, this Engine Oil Module kit delivers factory-quality components and a straightforward installation. This Engine Oil Module is the definitive choice for operators who demand reliable engine lubrication and long-term durability.
The Engine Oil Module Housing is the main structural component of this assembly, cast from high-strength aluminum alloy. It integrates the oil filter cavity, oil cooler mounting surface, and pressure valve port. Precision-machined sealing surfaces ensure leak-free operation, and the lightweight design contributes to overall engine weight reduction.
This Engine Oil Module Housing is designed to withstand oil pressures up to 10 bar and temperatures up to 150°C, providing a durable foundation for all module components.
This cover seals the oil filter housing and provides access to the filter element. In the Engine Oil Module, it is made of die-cast aluminum with a built-in O-ring groove. The cover is secured with the provided bolts and includes a central threaded boss for the filter element retention.
The seal ring is made of high-temperature FPM rubber, ensuring a leak-proof seal even under thermal cycling and pressure variations.
This plate-type oil cooler is a critical component of the Engine Oil Module, using engine coolant to regulate oil temperature. It features a stack of corrugated plates that maximize heat transfer surface area while maintaining a compact footprint.
The included gasket seals the oil cooler to the housing, preventing coolant and oil cross-contamination. This Oil Cooler with Gasket is rated for heat rejection up to 30 kW, ensuring stable oil temperatures under heavy loads.
This copper sealing washer is used under the screw plug to provide a reliable seal. In the Engine Oil Module, it conforms to DIN 7603 standards with dimensions A38X44. The copper material offers excellent resistance to oil and temperature, ensuring a leak-free connection.
This steel screw plug seals an oil gallery port in the Engine Oil Module housing. It features a hexagon socket drive and a M38X1.5 metric thread. The plug is zinc-plated for corrosion resistance and comes pre-coated with thread sealant.
This high-efficiency filter element removes contaminants down to 10 microns from the engine oil. In the Engine Oil Module, it features a pleated cellulose media with a metal end cap and an integral O-ring for sealing against the housing.
The filter element has a dirt-holding capacity of 25 grams and a bypass valve that opens at 2.5 bar differential pressure, ensuring oil flow even if the filter becomes clogged.
The Pressure Limiting Valve protects the Engine Oil Module and engine from excessive oil pressure. It is a spring-loaded poppet valve that opens at a preset pressure of 6.5 bar, diverting excess oil back to the sump.
This valve ensures consistent oil pressure across all engine speeds and loads, preventing damage to bearings and other critical components.
These M8 flange bolts secure the oil cooler and other components to the Engine Oil Module housing. Grade 8.8 with a zinc-nickel coating, they provide reliable clamping force and corrosion resistance. The MAN183-B1 specification ensures compatibility with the C7H engine.
These shorter M8 flange bolts are used for securing the filter cover and other auxiliary components in the Engine Oil Module. Grade 8.8 with a zinc-nickel coating, they provide reliable fastening in confined spaces.
This Oil-Air Separator is a vital component of the Engine Oil Module, removing oil mist from the crankcase ventilation gases. It features a high-efficiency coalescing filter media that returns oil to the sump while allowing clean gases to be routed to the intake.
The included seal ring ensures a leak-free connection to the housing, and the separator is designed for long service life with minimal maintenance.
The Engine Oil Module combines filtration, cooling, and pressure regulation in a single unit, ensuring clean, cool, and correctly pressured oil reaches all engine components. This reduces wear, extends engine life, and improves reliability.
This Engine Oil Module kit includes every component required for a full service or replacement – housing, cover, cooler, filter element, pressure valve, separator, and all fasteners. The all-in-one solution simplifies maintenance and ensures compatibility.
The Engine Oil Module uses a premium filter element with 10-micron filtration and a plate-type oil cooler that provides 30 kW of heat rejection. This ensures optimal oil cleanliness and temperature, even under severe operating conditions.
The Engine Oil Module is manufactured to the exact OEM specifications, guaranteeing a perfect fit on the Sitrak C7H. The precision-machined housing and matched components ensure proper oil flow and reliable sealing, reducing the risk of oil leaks and engine damage.
