Product Details

The Moroso 64886 is a precision-engineered Gilmer-style vacuum pump pulley designed for high-performance racing applications. This 28-tooth pulley is specifically designed to work with Moroso 3-vane and 4-vane racing vacuum pumps, as well as similar OE-style smog pumps that utilize the standard 3-bolt mounting pattern.

Key Features:

  • 28-tooth Gilmer drive design with 3/8" pitch
  • 3.313" (84.2mm) outer diameter for optimal drive ratio
  • Accepts standard Gilmer belts up to 3/4" wide
  • Precision CNC-machined from aircraft-quality aluminum
  • Hard-coat blue anodized finish for extended durability and corrosion resistance
  • 3-bolt mounting pattern with 1.160" bolt circle
  • Direct bolt-on installation with no modifications required

This pulley is compatible with Moroso vacuum pump part numbers 22640, 22641, 22642, 22643, 22644, 22840, 22842, and 22843, as well as their interchangeable drive components. The Gilmer-style toothed design ensures positive engagement and prevents belt slippage under high-RPM racing conditions, making it an essential component for maximizing crankcase vacuum in high-performance and racing engines.
