Mercedes Sprinter Crankshaft Pulley / Harmonic Balancer – IPD | VS30 2.0L OM654 Diesel | #6540300803 (2023+)

A failed crankshaft pulley on a VS30 Sprinter doesn't just affect the serpentine belt — when the internal rubber damper separates, torsional vibration from the crankshaft travels unchecked through the accessory drive and into the engine's rotating assembly, accelerating wear on bearings, belts, and every component in the drive system. This is the Genuine Mercedes-Benz OEM crankshaft pulley with integrated harmonic balancer for VS30 Sprinters equipped with the 2.0L OM654 diesel engine, a direct replacement that restores proper belt drive and torsional vibration control.

What This Part Does

The crankshaft pulley mounts to the front of the crankshaft and serves two critical functions simultaneously. The outer poly-V groove drives the serpentine belt, which powers the alternator, water pump, A/C compressor, and power steering pump. The internal rubber-bonded damper ring — the harmonic balancer — absorbs and dissipates the torsional pulses that the crankshaft generates with each combustion event, preventing those vibrations from resonating through the drivetrain. On a diesel engine like the OM654, which produces strong combustion pulses at low RPM, the harmonic balancer is especially important for protecting crankshaft bearings and reducing NVH. When the rubber element degrades, cracks, or separates from the outer ring, the pulley wobbles, belt alignment is disrupted, and vibration levels rise sharply.

Common Symptoms of a Failing Crankshaft Pulley

• Visible wobble or runout in the pulley when the engine is running
• Serpentine belt walking off its path, wearing unevenly, or throwing off the drive
• Squealing, chirping, or rhythmic belt noise tied to engine RPM
• Increased engine vibration, especially at idle or under light load
• Cracking, separation, or deterioration of the rubber damper element visible on inspection
• Accessory failures (charging, cooling, A/C) caused by belt misalignment or slippage

When to Replace

Replace when the rubber damper shows cracking, separation, or the outer ring has moved relative to the inner hub. Also replace as part of a front-of-engine service — the crankshaft bolt must always be replaced at the same time as it is a torque-to-yield fastener that cannot be reused. Inspect the serpentine belt, tensioner, and idler pulley at the same time and replace as a set.

VS30 OM654 Specific — VIN Verification Required

This crankshaft pulley is for VS30 Sprinters equipped with the 2.0L OM654 diesel engine. It is not compatible with VS30 models equipped with the 3.0L OM642 or NCV3 Sprinters equipped with the 2.1L OM651. Always verify your engine code and VIN before ordering.
