13477-38010 TOYOTA 22R 22RE ENGINE CRANKSHAFT PULLEY

Introduction to Operational Safety

Maintaining the rotational integrity of classic Toyota engines requires components that can withstand decades of mechanical stress. This crankshaft pulley is specifically designed to manage harmonic vibrations and ensure the stable operation of belt-driven accessories. By effectively dampening torsional fluctuations, it protects the crankshaft from premature wear and enhances the overall safety of the vehicle’s powertrain during both idling and high-load conditions.

Manufacturing and Performance Standards

This unit is manufactured to match the original equipment specifications for Toyota 4Runner and Pickup models produced between 1984 and 1995. It is fully compatible with the 22R, 22RE, and 22RTEC 2.4L four-cylinder engines, as well as the 3VZE V6 configurations in certain regional markets. With an external diameter of 140mm, a center hole of 48mm, and a total height of 40mm, it provides a precise fit that eliminates belt slippage and ensures consistent power delivery to the alternator, power steering pump, and air conditioning compressor.

Advanced Material Standards

To achieve superior durability, we utilize high-grade ductile iron for the main body of the pulley, offering excellent tensile strength and fatigue resistance compared to standard grey iron. The damping layer is composed of high-performance elastomers that remain flexible across a wide temperature range, preventing the rubber from cracking or hardening over time. Each component undergoes dynamic balancing during the final assembly stage to ensure vibration-free rotation and a significantly extended service life in demanding environments.
