Schaeffler engineers have always advised against fitting mismatched clutch components, and have now identified a specific case where the installation of a non-LuK clutch, combined with a genuine LuK concentric slave cylinder(CSC), can result in clutch release system leakage.
Schaeffler has updated its packaging to include a warning label, advising against this practice. The affected LuK CSC (510 0180 10)will now feature a non-verbal instruction that explicitly tells technicians not to use the component in conjunction with a non-LuK manufactured clutch. A large number of Alfa Romeo, Fiat and Vauxhall/Opel models are affected by this development.
Some non-LuK manufactured clutches deviate from genuine Schaeffler specifications and standards and require higher pedal loads to operate. As a result, this can subject the CSC to excessive loading, which can cause a roughening of the guide sleeve. This then causes the seal to wear prematurely and, therefore, leak.
In order to prevent this type of damage, this particular CSC should only be installed with LuK-manufactured clutches or as a complete LuK RepSet Pro solution, including a LuK CSC. Schaeffler recommends that this is also best practice for all LuK clutch components, which have been designed, manufactured and precision-matched to work perfectly together.
