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
2004-2011 E63 E64 BMW M6

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes the ECS Kevlar Reinforced Drive Belts, tensioner assemblies, and new tensioner pulleys. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

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

Also known as a shock damper, the accessory belt tensioner is used to tension the air conditioning compressor belt. This ensures proper contact with the belt drive pulleys and prevents premature wear from improper tension.

If your belt is wearing prematurely or has excess slack, your belt tensioner may be to blame. Replace it with this high-quality Bremmen Parts tensioner to ensure proper tension and air conditioning functionality.

Is your BMW making a chirping or grinding noise at idle? The culprit is frequently a failing alternator decoupler pulley. Unlike a traditional solid pulley, this Overrunning Alternator Pulley (OAP) allows the alternator rotor to "freewheel" when engine speeds drop suddenly. This specialized function protects your BMW drive belt and belt tensioner from excessive snap-back, vibration, and "belt slap."

Prevent Catastrophic Engine Failure

Over time, the internal clutch mechanism can seize or slip, leading to accelerated wear or total serpentine belt failure. On BMW engines, a snapped belt can be ingested through the front main seal, causing catastrophic engine damage. Replacing this pulley is a cost-effective preventative maintenance step that restores smoothness to your accessory drive without the high cost of a complete alternator replacement.

Features & Benefits:

Lowers the load on the drive belt, tensioner, and AC compressor.
Stops "belt slap" and rhythmic chirping noises during deceleration and idle.
Direct Replacement with high-quality construction ensures perfect fitment and long-term durability.
Essential Maintenance for N52 engines

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.

This item is 70mm Diameter. Please check the diameter before ordering.
