The differential bevel gear in Volvo L90 and L120 loaders is a precision-machined crown and pinion gear set designed to transfer torque from the transmission to the wheel axles. The gear is typically installed inside the final drive housing of the differential, converting longitudinal rotational motion from the drive shaft into lateral motion for the wheels at a 90-degree angle. OEM bevel gears, such as VOE11712502, feature tooth counts of 15 × 31 and an outer diameter around 203 mm, engineered to transmit torque up to 12,000 Nm without tooth fatigue. High-strength alloy steel with heat-treated surfaces at 58–62 HRC hardness ensures high wear resistance and durability under continuous heavy-load operation. Proper alignment and preload are critical to prevent premature tooth wear, backlash, or gear failure.
The gear geometry is designed to handle both radial and axial loads generated by the wheel during heavy lifting, rough terrain, and high traction conditions. Tooth contact patterns are optimized using computer-aided stress analysis, ensuring uniform load distribution across the tooth flanks. Tolerances on tooth spacing and helix angles are within ±0.02 mm to maintain smooth torque transmission and minimize vibration. Lubrication with high-pressure EP gear oil reduces friction and prevents micro-pitting over more than 5000 operating hours. Using OEM or high-quality aftermarket bevel gears enhances differential longevity, reduces maintenance frequency, and ensures consistent performance in both L90 and L120 loader operations.You can order and buy Volvo L90 and L120 bevel gear from Iran by contacting us through whatsaap and email.

Volvo loader differential bevel gear material and hardness
The differential bevel gear in Volvo L90 and L120 loaders is manufactured from hardened chromium-molybdenum alloy steel, providing a combination of high tensile strength and surface hardness suitable for heavy rotational loads. The gear teeth undergo induction or controlled thermal surface hardening to achieve a hardness of 58–62 HRC, while the core remains ductile enough to absorb impact stresses. This alloy design allows the bevel gear to withstand radial and axial loads up to 12,000 Nm torque without cracking or excessive wear, extending service life to over 5000 operating hours under heavy-duty conditions.
The wear hardness and geometry of the bevel gear are optimized according to ISO 6336 standards and CAD stress analysis, ensuring uniform load distribution and reduced point contact. The chromium-molybdenum alloy resists fatigue and micropitting, lowering friction and increasing torque transmission efficiency above 97%. Tooth spacing and helix angle tolerances are maintained within ±0.02 mm, and lubrication with high-pressure EP gear oil prevents excessive wear, overheating, or tooth failure, ensuring the safety and durability of the differential and wheel axles.
