Introducing our Turner Motorsport Crank Seal Guard – the essential shield for your BMW's engine integrity. Safeguarding the heart of your vehicle, this meticulously designed guard offers robust protection for the crank seal concealed behind the harmonic balancer.

Considered an indispensable maintenance component for your BMW, the Crank Seal Guard acts as a crucial defense against a potential and preventable catastrophe involving your accessory belt. Facing the reality of potential oil or coolant leaks in your engine, this guard becomes a reliable barrier, preventing these fluids from reaching the accessory belt. The consequence of a compromised belt includes walking, slipping, fraying, and rubber particles finding their way behind the harmonic balancer and into the crank seal – a scenario that can lead to severe engine failure.

Let's be honest, engine leaks are a common occurrence, and whether your engine is currently leaking or not, the Crank Seal Guard is a proactive measure against future threats. The wear and tear on the accessory belt due to oil and coolant exposure can result in slipping, tearing, or, worst-case scenario, belt snapping – posing a significant risk to your engine's well-being.

Prepare your car for the long haul and protect the vital components, It's not a matter of "if" but "when" your belt will become a problem, and our Crank Seal Guard is your proactive solution. Rigorously tested on N52/N54/N55 and S55 for 100% confirmed fitment, it stands as a reliable guardian for your engine's health. Invest in the protection your BMW deserves with the Turner Motorsport Crank Seal Guard.

Key benefits:

Protect crank seal from rogue accessory belts and their shredded debris
Optimized to fit N52, N54, N55, and S55 engines
Rigid design that fits within the space constraints between the engine block and harmonic balancer
Zinc-coated fasteners for corrosion and oxidation resistance
Design:

Modeled and designed from FARO laser scanning and Solidworks CAD
Manufactured from 6061 billet aluminum
Turner blue anodizing
Installation:

It is a good idea to note how your belt is routed before starting the installation.

2 securing bolts for crank seal guard - Torque value of 20Nm

You will find either 6 or 8 E10 bolts are holding the harmonic balancer depending on the engine.

E10 (P#11237564511)
N52: 6 bolts - Torque value of 25nm
N54: 6 bolts - Torque value of 35nm
N55: 8 bolts - Torque value of 35nm

E10 (P#11237575488)

These are the replacement drive belts used in our Turner Pulley Kit on the S85 V10 engine (E60 M5 and E63/E64 M6). These belts are shorter than the stock belt since our underdrive crank pulley is a larger diameter than stock. Because of the different lengths, you cannot use a stock belt with the Pulley Kit. This set of belts includes the main drive belt (6PK-1400) and the A/C belt (6PK-1045).

This belt set fits the following BMWs with the Turner Pulley Kit:
2006-2010 E60 BMW M5

The vibration damper in the E70 X5 35d 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
