Schaeffler for LuK dual mass

Schaeffler Automotive Aftermarket Australia offers more than 200 LuK dual mass flywheel (DMF) part numbers to suit the ever growing number of vehicles on New Zealand and Australian roads that have been fitted with these uniquely designed flywheel systems.

The LuK DMF is a major drive train component that has modernised vehicle performance and comfort, ranging from the largest to the smallest vehicles on our roads.

Over the past three decades, Schaeffler Automotive Aftermarket developed and provided repair solutions, including the DMF, and has thereby contributed to increase professional repairs of cars of all shapes and sizes.

Schaeffler has manufactured more than 100 million LuK dual mass flywheels. Today, in Europe alone, there are more than 85-million vehicles equipped with a DMF – this includes vehicles with manual transmissions, diesel vehicles and vehicles that use the LuK double clutch.

The main function of the LuK dual mass flywheel is to super-efficiently transfer power from the engine to a vehicle clutch and transmission system, along with providing highly effective damping of engine vibrations, ensuring a smoother and quieter ride, no matter what type or size of car.

LuK has further improved its DMF design with the addition of a centrifugal pendulum type absorber, which has proven to be extremely successful as vehicle manufacturing continues to trend towards much smaller engine capacities.

The LuK dual mass flywheel has transcended from a niche, prestige component, to a high volume product. Like any automotive drive train component, DMF’s are also subject to wear, with exact replacement an absolute necessity to avoid future gearbox and drive train damage or premature wear.

To ensure absolute accuracy in DMF replacement, Schaeffler Automotive Aftermarket offers LuK RepSet DMF dual mass flywheel replacement solutions, containing everything that the repairer needs to efficiently perform these replacements.

It is important for automotive repairers to note that no single rule can apply to the checking of dual mass flywheel (DMF) wear. In relation to LuK DMF products, all part numbers vary significantly in the amount of maximum rotational movement (freeplay) and lateral movement (rock) permissible.

When assessing a LuK DMF, Schaeffler Automotive Aftermarket advises to measure the amount of freeplay in degrees of movement or by the number of ring gear teeth. The rock is measured in millimetres.

Many LuK DMF products, particularly diesel applications, are equipped with a friction control disc to provide extra dampening at startup or load change. When measuring the freeplay, the presence of a friction control disc must be known and taken into consideration.

The condition of the friction surface, the amount of grease loss, and other factors, need to be considered when assessing whether to replace a LuK DMF.

To make this easier for repairers, Schaeffler Automotive Aftermarket offers a DMF Special Tool that can help to assess wear levels on a LuK DMF. The company also provides a handy wall chart that includes detailed diagnosis requirements along with an array of supportive DMF technical information to assist repairers. There is even a special DMF replacement App available for instant access to this information.

LuK dual mass flywheels were designed for vehicles that require special harmonic vibration dampening characteristics to ensure long drive train life. Replacing a DMF with a solid mass flywheel is never correct.

While it may fit and not create any audible issues, it will only be a matter of time before serious gearbox and other potential engine and drive train damage
