Overview of Gates Timing Belt Pulley T42231

The Gates Timing Belt Pulley T42231 is engineered for reliable performance in Mitsubishi vehicles. Designed specifically as an engine timing belt idler pulley, it supports the timing belt system in models such as the Mitsubishi Eclipse, Galant, Lancer, and Outlander.

  • Constructed from durable steel material for strength and longevity
  • Inside diameter measures 10 mm, ensuring precise fitment
  • Width of 24 mm accommodates proper belt alignment
  • Outside diameter of 60 mm for optimal belt tension
  • Smooth backside contact surface to reduce wear on the timing belt
  • Non-flanged end design for compatibility with specific engine configurations

Detailed Product Description

The Gates Timing Belt Pulley T42231 is a critical component within the engine valve train system, functioning as an idler pulley to maintain correct tension and routing of the timing belt. Made from steel, this pulley offers durability and resistance to wear under high engine stress. Its dimensions—10 mm inside diameter, 24 mm width, and 60 mm outside diameter—are tailored to fit Mitsubishi models including the Eclipse, Galant, Lancer, and Outlander. The smooth backside contact surface minimizes friction and belt degradation, contributing to the overall longevity of the timing belt system.
