Detailed Product Description

This Gates Timing Belt Pulley T42001 is part of the Timing Belt Pulley product line, which focuses on components critical to the valve train system's timing belt operation. The pulley is made from steel, providing the necessary rigidity and resistance to wear under engine stress. Its dimensions—10.4 mm inside diameter, 31 mm width, and 60 mm outside diameter—are tailored to maintain proper belt tension and alignment in compatible Geo and Isuzu models. The smooth backside contact surface minimizes friction and belt degradation, contributing to consistent engine timing and performance.
