The crown wheel and pinion gear set in the Volvo L90 and L120 wheel loaders plays a critical role in reducing rotational speed and increasing output torque from the transmission to the front and rear axles. The pinion gear, typically designed with a spiral bevel angle between 14 and 20 degrees, operates with a standard gear ratio ranging from 3.8 to 4.5. The outer diameter of the pinion commonly ranges from 80 to 110 mm, while the crown wheel diameter is approximately 300 to 350 mm. These gears are manufactured from alloy steel and undergo carburizing and quenching to achieve a surface hardness of 58 to 62 HRC and a core hardness of 30 to 35 HRC. A gear module of around 5 mm ensures uniform load distribution and smooth performance under heavy duty operating conditions.
The crown wheel and pinion assembly is installed inside the axle housing at the final drive section, where it transmits axial and radial loads to adjustable tapered roller bearings. Proper backlash between the crown wheel and pinion is typically set between 0.15 and 0.25 mm to minimize noise and prevent premature wear. Under normal operating conditions, the gear set can efficiently transmit torque exceeding 1200 Nm. Lubrication with API GL-5 gear oil of 80W-90 viscosity provides extreme pressure protection, reduces tooth surface fatigue, and extends service life beyond 8000 operating hours.You can order and buy Volvo L90 and L120 crown wheel and pinion from Iran by contacting us through whatsaap and email.

Dimension and information of crown wheel and pinion for Volvo Loader L90 and L120
The final drive system of the Volvo L90, L120, and BM loaders utilizes a specific spiral bevel gear set known as the crown wheel and pinion. For the Volvo BM L90C and L120C models, the differential side gear assemblies carry Volvo OE reference numbers 17415136 and 1524588 . These hardened steel components are engineered to exacting tolerances to manage high torque loads and ensure smooth power transfer to the wheels .
The ring gear and pinion are matched sets designed for optimal tooth contact patterns and quiet operation. Technical specifications for these drivetrain components are critical for service replacements . These parts are common across multiple Volvo articulated hauler models, indicating a shared engineering platform . Precise backlash and preload settings are mandatory during installation to guarantee long service life.
