ZF 5840.300.732 DISC CARRIER | OEM Genuine Part

Overview

The ZF 5840.300.732 DISC CARRIER is a precision-engineered OEM genuine component designed for heavy-duty construction machinery transmissions. This critical part serves as the central hub that houses and supports the clutch disc pack within the transmission assembly, ensuring proper torque transfer and smooth gear engagement. Located within the planetary gear set, the disc carrier interfaces directly with the transmission housing and rotating shafts to maintain alignment under extreme loads. The SKU 5840.300.732 is manufactured to ZF’s exacting tolerances, using high-strength alloy steel to withstand the thermal and mechanical stresses common in excavators, wheel loaders, and graders. When paired with a properly functioning 2098109042 DIFFERENTIAL and 2098309011 CROWN WHEEL, this disc carrier ensures reliable power distribution across the drivetrain.

Symptoms of Failure

• Erratic gear engagement or slipping: A worn disc carrier causes uneven clutch pack pressure, leading to delayed or rough shifting under load.
• Metallic grinding noises from the transmission: Damaged splines or carrier bore wear produce audible metal-on-metal contact during operation.
• Oil contamination with metallic debris: Flaking or cracking of the carrier surface introduces steel particles into the transmission fluid, visible during oil changes.
• Reduced power transfer efficiency: The disc carrier’s inability to maintain clutch pack alignment results in torque loss, especially during uphill or heavy-load operations.

Technical Specifications

Compatibility

This disc carrier is engineered for ZF’s WG series powershift transmissions commonly used in construction machinery. Based on its design and spline configuration, the 5840.300.732 is compatible with the following ZF transmission models: WG180, WG200, and WG211. These transmissions are found in equipment such as Case, New Holland, and JCB wheel loaders and telehandlers. For optimal performance, this part should be installed alongside a 2099209001 DIFFERENTIAL and a 2098309010 DIFFERENTIAL HOUSING to ensure proper gear alignment and load distribution.
