With the design of the crank, pulley, and timing chain sprocket assembly in the MINI Cooper R56, there is the potential for catastrophic damage. If the bolt which secures the pulley hub and sprocket were to loosen over the life of the car, it would be possible for the timing chain sprocket to become misaligned on the crank. This could lead to damaged pistons, bent valves, or worse. The CravenSpeed Crank Bolt Lockdown Plate eliminates this possibility by making it physically impossible for the bolt to loosen itself.

The function of the plate is incredibly simple. It installs onto the crank pulley via the included extended pulley bolts. The triangular cutout in the center engages on the hex head of the bolt, preventing it from backing out. Problem solved!

Installation of the plate is a snap. When attaching your crank pulley, simply slide the plate in place over the hub bolt, and then fasten the plate and pulley to the hub with the included high strength grade 10.9 bolts. We've also included some Loc-Tite to ensure that the pulley bolts will stay put. The plate itself is CNC machined in the USA from 6061 aluminum and anodized with a classic CravenSpeed red.

NOTE: A harmonic dampener or crank pulley is not included with this product. Only the lockdown plate, 3 M8 bolts, and Loc-Tite are included.

    This product takes away the worry of the crankshaft bolt ever having a chance of backing out, It really should be a standard part of any timing belt change!
