Gear
Volvo

This gear is a key element in a transmission or secondary drive system, translating rotational input into controlled output with precise tooth engagement. Proper gear geometry and material hardness sustain reliability under heavy torque, high speeds, and fluctuating loads that trucks commonly encounter. Surface treatments and heat treatment enhance wear resistance and longevity, while accurate timing and alignment ensure smooth power transfer and minimal noise. In service, gears are inspected for chipped teeth, pitting, or excessive backlash, all of which can disrupt performance and shorten service life. Replacement must consider gear pair compatibility, shaft alignment, and lubrication requirements to maintain system efficiency. For fleet operators, durable gears reduce downtime and support predictable driveability. Source One Parts Center carries gears and matched assemblies designed for robust, long‑term performance.
