Crankshaft Standard (STD)
This standard size crankshaft (STD) is a precision-engineered rotating assembly component used in several iconic Porsche air-cooled engines.

Fits:

  • Porsche 911 1984-1986 3.2L
  • Porsche 911 1987-1989 3.2L G50
  • Porsche 911 1984 -1989 3.3L Turbo (930)
  • Porsche 964 (911) TURBO 3.3L 1991-93

Designed to maintain original journal dimensions and deliver exceptional strength, this crankshaft plays a crucial role in preserving the smoothness, reliability and performance expected from these high-value flat-six engines.

Whether performing a classic restoration, a bottom-end refresh or a full performance rebuild, this crankshaft is essential for ensuring correct bearing clearances, optimal lubrication and long-term engine integrity.

What the Engine Crankshaft Does

This crankshaft is responsible for key engine functions, including:

  • Converting piston motion into rotational torque that drives the transmission
  • Maintaining accurate journal diameters to support proper bearing lubrication
  • Providing smooth, balanced rotation across the engine’s entire RPM range
  • Distributing oil internally through precision-machined lubrication galleries
  • Supporting turbocharged loads with a strong, durable crank web and journal design
  • Forming the foundation of the bottom-end rotating assembly

A correct standard-size crankshaft is vital to the long-term reliability and performance of any air-cooled Porsche flat-six.

Why Crankshafts Can Fail

Even though Porsche engineered these crankshafts for durability, decades of use and performance driving can lead to wear or damage. Common causes of failure include:

  • Oil starvation resulting in journal scoring or bearing failure
  • Metal fatigue from high RPM use, boost pressure or detonation
  • Contamination in the oil supply causing abrasive wear
  • Overheating weakening the crankshaft’s molecular structure
  • Incorrect machining from past rebuilds creating imbalance or mismatched tolerances
  • Severe knock events bending or cracking the crankshaft
  • High-mileage wear reducing journal roundness and bearing clearances

Symptoms of crankshaft-related failure include low oil pressure, metallic knocking, vibration, bearing debris in oil, and uneven rotation during teardown.

Why You Should Replace a Damaged or Worn Crankshaft

Installing a new or precision-built standard size crankshaft—designed to match original Porsche performance tolerances—ensures a strong, balanced and reliable engine rebuild.

Key benefits include:

  • Restored bearing clearances and stable oil pressure
  • Smooth, balanced engine rotation at all RPM ranges
  • Reduced vibration and improved power delivery
  • Enhanced reliability under turbocharged loads
  • Prevention of severe bottom-end failures
  • Increased lifespan of pistons, rods and bearings
  • Assurance of correct geometry for high-performance use

For high-value Porsche models like the 911 Carrera 3.2 and Turbo variants, a correct, high-quality STD crankshaft is one of the most critical investments in any rebuild.
