Clear BMW chassis

Please ensure your correct model is selected

Your BMW's drive belts are wear items, and will degrade and crack over time. Don't wait until you have a belt failure... don't get stranded! Replacing your BMW's belts, such as the alternator belt, power steering belt, air conditioning AC belt, or serpentine belt is a low cost insurance policy to preventing a break down -- or worse, engine damage. We recommend checking your belts every 10,000 miles. If your belts have excessive cracks, dry rot, missing teeth and/or grooves, are cause noise, it's time for new ones.

While also inspecting your serpentine belts, also check for wear or resistance in the pulleys. The tensioner pulley and deflection pulley are the primary sources for belt squealing. The rubber-isolated pulleys can also break apart, leading to total belt failure. We sell the tensioner and deflection pulleys for the M50 engine family used in the E34, E36, E39, E46, X5, Z3, and Z4.

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

Over time, accessory belts begin to wear out and crack. This can lead to the belt slipping, squeaking, or even snapping.
