PUMPS MULTI-PLATE CLUTCH KAMOKA
- 11.06.2026
KAMOKA is expanding its product range to include multi-plate clutch pumps. This new product line has been developed for repair shops, distributors, and end-users seeking reliable parts for drivetrain systems in passenger cars and light commercial vehicles.
The multi-plate clutch pump is a key component of the system responsible for transmitting torque between the vehicle’s axles. In vehicles equipped with selectable four-wheel drive, its task is to generate the appropriate oil pressure that enables the multi-plate clutch to function properly. The system’s response speed, drivetrain stability, and predictable vehicle behavior in variable road conditions depend on the pump’s efficiency.
The multi-plate clutch operates in a demanding environment. While driving, the system must respond to changes in traction, differences in wheel speeds, vehicle load, and the driver’s driving style. When the drivetrain controller detects the need to engage the second axle, the pump generates the pressure necessary to engage the clutch disc pack. This allows torque to be transferred where it is needed, improving traction and driving stability.
KAMOKA offers multi-plate clutch pumps designed for professional drivetrain repairs. The product range includes 17 part numbers, allowing you to select the right component for specific vehicle applications. Example product codes include: HP001, HP002, HP003, HP004, HP005.
One of the key features of KAMOKA pumps is parameter consistency and the stability of the pressure generated by the pump. In practice, this means predictable system operation and proper oil supply to the multi-plate clutch at the correct pressure. Stable pressure is crucial because a value that is too low or irregular can lead to delayed drivetrain response, incomplete clutch engagement, or controller errors.
The pump in a multi-plate clutch system must operate smoothly and effectively under various operating conditions. During daily driving, the system may be activated multiple times—when starting, accelerating, driving on wet surfaces, snow, mud, inclines, or in situations where traction is lost. Therefore, not only the pump’s performance itself is important, but also the consistency of its operation.
KAMOKA multi-plate clutch pumps are equipped with an efficient pre-filter that helps protect the system from contaminants in the oil. This is important because the oil operating in a multi-plate clutch system can accumulate fine operational contaminants over time. Effective pre-filtration supports proper pump operation and reduces the risk of disruptions in oil flow.
Another key feature of KAMOKA products is resistance to temporary flow restrictions. In drivetrain systems operating under variable loads, conditions may arise where oil flow is temporarily restricted. The pump must maintain stable operation and ensure proper pressure so that the drivetrain system can function without disruption.
Seals resistant to temperature fluctuations and transmission oil are also of great importance. The multi-plate clutch pump operates in contact with oil and is exposed to varying thermal conditions. The system temperature can rise during aggressive driving, operation under load, frequent engagement of the drive, or driving in more challenging conditions. The seals’ resistance helps maintain tightness and stable operating parameters over a long period.
Symptoms of a multi-plate clutch pump failure can vary and often depend on the design of the specific drivetrain. Typical warning signs include problems engaging the drive, delayed response of the rear or front axle, error messages regarding the AWD system, jerking during takeoff, uneven system operation during acceleration, reduced traction, or the system switching to emergency mode. In some cases, the driver may notice that the vehicle behaves like a single-axle drive car, even though it is designed to use an on-demand drive system.
System diagnostics should include checking for errors stored in the control unit, verifying the pump’s operating parameters, assessing the oil condition, inspecting electrical connections, and examining the multi-plate clutch itself. It is very important not to limit diagnostics solely to the pump itself. Similar symptoms may also result from contaminated oil, filter issues, mechanical wear of the clutch, damage to the control unit, or an interruption in the electrical system.
Replacing the multi-plate clutch pump is often one of the key steps in repairing the on-demand drive system. Using a functional component helps restore proper pressure in the system, improve clutch response, and reduce the risk of further torque transmission issues. This is particularly important in vehicles operated under variable conditions—on wet, snowy, or unpaved roads, or under frequent heavy loads.
The multi-plate clutch pump affects not only driving comfort but also safety. A properly functioning drivetrain helps maintain traction during takeoff, acceleration, and driving on surfaces with reduced traction. If the pump fails to generate sufficient pressure, the clutch may not engage properly, and the vehicle may lose some of its drivetrain performance.
KAMOKA products are designed with a focus on application-specific fit, stable operation, and durability under typical operating conditions. For multi-plate clutch pumps, operating parameters, the durability of sealing components, and proper oil flow are of particular importance. It is these characteristics that determine whether the system will operate smoothly and predictably after a repair.
In KAMOKA’s product range, multi-plate clutch pumps are an important addition to the lineup of drivetrain components. This is a solution for workshops that repair vehicles with a selectable drivetrain and require parts to effectively restore the system’s proper operation.
KAMOKA multi-plate clutch pumps are now available in the brand’s product range. Specific applications can be found in the catalog and through KAMOKA distributors.
