The vibration damper in the 335d is a common failure item and can fail at as low as 60 thousand miles leaving you stranded. This kit includes everything needed to replace your vibration damper and service your drive belt system! Vibration Dampers (also called Harmonic Dampers or Harmonic Balancers) absorb and remove unwanted vibrations due to torsional twisting of the crankshaft. During cylinder combustions, the crank quickly flexes ever so slightly, resulting in resonance vibrations. These vibrations could lead to damage of the crankshaft or crank bearings over time if not accounted for. The vibration damper helps to eliminate these vibrations, thereby extending the life of your engine's mechanical components and preventing damage. If your vibration damper has failed, you will likely notice excess engine vibrations or shaking that will gradually get worse, especially around certain RPMs where the vibration resonance is most pronounced. This kit includes all of the components necessary to replace your damper with an OEM damper from Corteco, including belts, pulleys, hardware, and more. Also included in this kit is a brand-new line of specialty tools from Schwaben designed specifically for this replacement! You will get a Crankshaft Pulley Turner Tool, Stretch Belt Remover/Installer, T50 Alternator Wrench, and a 15/16" Pass-Through Socket, all included to make swapping out your old damper a quick and easy process! Standard tools you might need but are not included: 8mm Drill Bit (to use as flywheel locking pin) 32mm Fan Clutch Wrench - You may want a second 32mm to hold the coupler in place 24mm Box Wrench - For releasing tensioner Torque Wrench - To torque new crankshaft bolts Breaker Bar - to drive the crankshaft bolts further
