IAP 69mm Cast Iron 8-Dowel VW Crankshaft

Reliable Performance for Budget-Minded Builds

The SCAT Volksaver (IAP 10692) is a precision-engineered 69mm counterweighted crankshaft designed for VW aircooled enthusiasts who need quality without the premium price tag of a forged unit. Cast from high-grade iron and featuring an 8-dowel drive, this crank is the perfect foundation for daily drivers and mild performance street engines. By adding counterweights to the standard stroke, this crankshaft reduces engine vibration and extends the life of your main bearings.

Versatile Engine Fitment and Compatibility

This 69mm stroke crankshaft is the standard replacement for 1300cc, 1500cc, and 1600cc Volkswagen engines. It also serves as the ideal starting point for popular big-bore upgrades, including 1641cc (87mm bore), 1776cc (90.5mm bore), 1835cc (92mm bore), and 1914cc (94mm bore) configurations. This unit is specifically rated for mild applications that do not exceed 110hp or 5500 RPM.

Pro Tech Tips for Installation

Tip 1: Match Your Flywheel Pattern. Because this crankshaft features an 8-dowel pattern for increased strength, you must use a matching 8-dowel flywheel. This configuration is significantly more robust than the stock 4-dowel design and is essential for preventing dowel pin shearing in performance-oriented builds.

Tip 2: Verify Journal Sizes and Bearing Fit. Always "dry fit" your main and rod bearings before final assembly. While this crank uses standard VW journals, it is critical to use a micrometer to verify the dimensions and ensure your bearings provide the correct oil clearance. If you order bearings from Appletree Auto at the same time as your crank, our team will cross-reference them to ensure compatibility.

Tip 3: Precision End Play Adjustment. Proper crankshaft end play is vital for the longevity of your thrust bearing. Use a dial indicator to measure and set the end play between .003" and .005" (0.07mm to 0.13mm). This is achieved by selecting the correct combination of three shims installed between the flywheel and the rear main bearing.
