VW Crankshaft Pulley - Rein 03G105243

Product Information

An Engine Crankshaft Pulley (also known as a harmonic balancer or crank pulley) is a wheel attached to the engine’s crankshaft. It serves two primary purposes:

• Power Transmission: It drives various engine accessories (such as the alternator, water pump, power steering pump, and air conditioning compressor) through the serpentine or V-belt.

• Vibration Dampening: The crankshaft pulley often includes a rubber damper to absorb vibrations created by the engine’s combustion cycles, protecting the crankshaft from excessive vibration and potential damage over time

• Engine Vibrations: A failing or damaged pulley can lead to excessive engine vibrations, particularly at higher RPMs, because it no longer dampens the crankshaft’s vibrations effectively
• Visible Belt Misalignment: If the pulley is damaged or wobbly, it can misalign the serpentine belt, which may be visible on inspection and could result in premature belt wear
• Power Loss to Accessories: A failing pulley can lead to reduced or intermittent power to accessories like the alternator, power steering, or air conditioning due to belt slippage or pulley misalignment

About Rein

Founded in 2007, CRP Automotive introduced the Rein Automotive line of OE-quality replacement parts to the aftermarket. And in just two short years, Rein Automotive has become very popular among both warehouse distributors and professional repair technicians. Rein is the German word for “pure”, and has come to be synonymous with quality in the automotive aftermarket. A true dealer alternative.

The Rein brand includes a growing number of “better than OE” parts for selected applications. These parts address known weaknesses and premature failures of factory parts. Many of these replacement and service solutions have been developed with the help of our Innovation Council, a hand-picked group of experienced professional repair technicians and shop owners throughout North America.

All Rein Automotive OE-quality parts are backed by the CRP Automotive standard, and are backed with a ISO 9001:2015 quality management system certification. Each year, CRP Automotive ships thousands of Rein Automotive brand products. And with widespread NAFTA market distribution through strategically placed warehouses in Cranbury, New Jersey and Puebla, Mexico - OE-quality products like Rein Automotive are delivered to customers both faster and more cost-effectively than ever before.

In 2017 Rein partnered with FCP Euro in competing a W204 C300 AER car for the 2017 season. The partnership focused FCP Euro to dive deep into the Rein catalog offering, and hundreds of new products were added and integrated into our catalog. Hundreds of new packages were created not only using the full part pine up of Rein products, but also the entire family of CRP products like Pentosin.

Rein is also an innovative brand, winning numerous trade awards — including multiple new product innovation awards at the annual AAPEX trade show.
