MMX Crankhub Capture Plate BMW S55/N55

MMR Performance Crankhub Capture Plate – BMW S55/N55 – MMR20-1002 Issues relating to the standard three-piece crank hub on the S55 & N55 engine are widely known, but include the need to ensure the OE crank bolt can’t loosen, which is one cause of the crank hub friction plates starting to slip. The crank bolt is susceptible to loosening due to the engine’s natural vibrations and harmonics, meaning that with just the slightest loss of torque, your timing will slip out of correct adjustment with potentially disastrous consequences. For the ultimate solution, which is strongly recommended for high powered, or track cars, you should plan to upgrade both this Capture Plate AND fit the MMR Single-Piece Crank Hub. Install of this Capture Plate is a simpler job to install and provides a great deal of added protection – making it a sensible ‘first upgrade’ for any S55/N55 car being used on the road if you don’t want to incur the full expense of the Single-Piece Crank Hub. Machined from T-6061 billet aluminium before being anodised in our trademark finish, the MMR Performance Capture Plate completely surrounds and secures the head of the OE crank bolt, making it physically impossible for it to turn or loosen. Secured to either the MMR one-piece crank hub, or the OE crank hub, the elongated slots ensure a perfect, secure installation, every time. Installation of the capture plate is also possible with the engine remaining in-situ, with just the need to drop the radiator, in order to gain adequate access to install.
