Mercedes W907 Oil Pump Suction Pipe A6541803001

Mercedes W907 Oil Pump Suction Pipe is an original lubrication system component from the Oil pumps and parts group, designed for use in Mercedes W907 series engines. The precise geometry of the suction channel ensures stable oil pump supply, which translates into safe lubrication pressure and a longer service life for the engine unit. Using an OEM component is a sensible choice for professional repairs where structural fit and predictable performance are essential.

Purpose and function in the lubrication system

The suction pipe in the oil pump system is responsible for drawing oil from the oil pan and delivering it to the pump while maintaining proper flow efficiency. In the design used in the Mercedes W907, the following are key:

• maintaining the correct oil immersion level under various engine operating conditions,
• minimizing pressure losses along the suction section,
• stable operation during changes in engine speed and oil temperature,
• protecting the pump against air intake during sudden acceleration and braking. Thanks to the factory-set geometry of the flow channels, the suction pipe works with the oil pump in a predictable manner, which is important for maintaining a proper oil film on friction components.

Advantages of using an original suction pipe

Using an original suction pipe in a Mercedes W907 is important for both the durability and operational safety of the engine. In practice, this means:

• secure fit to the oil pan and pump – no need for modifications or adjustments,
• preservation of factory oil flow parameters,
• compatibility with the mounting and sealing system in a given engine type,
• reduction of the risk of cavitation and pressure drops in the lubrication system. Choosing a used OEM component from this group is often more predictable than installing a cheap replacement with unverified geometry and material quality.

Component condition and service application

The oil pump suction pipe offered in this variant comes from disassembly and is classified as a used original Mercedes part. This type of component is particularly useful for:

• overhauling the bottom end of the engine,
• replacing the oil pump after seizure or pressure drops,
• preventive maintenance after a lubrication system failure,
• restoring the completeness of the system in engines after partial disassembly. Selecting a suction pipe from the same design family as the oil pump allows for system consistency and facilitates the diagnosis of potential oil pressure problems in the future.

Integration with the Oil pumps and parts system

The suction pipe is one of the key elements of the Oil pumps and parts group, responsible for oil distribution in the engine. In practice, it works with:

• the oil pump itself,
• the oil pan and its baffles,
• the oil channel system in the engine block,
• oil filtration components. If you are planning a comprehensive repair or upgrade of the engine area in your Mercedes and need other elements from the same group, such as pump housings, suction baskets, or return lines, check the available parts in the Mercedes Oil pumps and parts category.

Service and operational tips

When replacing the oil pump suction pipe in a Mercedes W907, it is worth paying attention to several assembly aspects:

• thorough cleaning of the oil pan and the area around the pipe mounting,
• verifying the condition of seals and replacing them with new ones,
• checking for play and the rigidity of the mounting,
• checking the patency of the suction channel before installation. To maintain stable lubrication system performance, it is also worth familiarizing yourself with the principles of selecting and servicing other vehicle components. Detailed procedures and practical tips can be found in the article Air conditioning and heating – part selection and maintenance for year-round comfort, which discusses the approach to used OEM components and service schedules in modern cars.
