The R52, R53 MINI Cooper S crankshaft harmonic balancer pulleys are known to fail. Here is a better and more cost effective solution.
PRW Fluid Dampers are made with an internal steel intertia ring that is
surrounded by a high viscosity silicone gel. The internal intertia ring
"floats" in the silicone gel to combat the engine harmonics at all RPM
ranges. Crankshaft and bearing life is significantly improved and you can
safely increase torque and horsepower.
Includes threaded bore holes to mount a crank trigger on the face of
the damper, thereby allowing ignition timing to be controlled and
adjusted externally.
Superior steel forgings and CNC machining ensure consistent finishes
and tolerances. The fluid dampening design enhances smooth blower
operation, and preserves main bearing life for engines that are tuned
to perform far above factory specifications. These dampers are SFI
certified to 12,500 RPM.
WMW recommends replacing the crank bolt anytime it is removed. We do have them in stock HERE |
