ZF 2052.209.109 DIFFERENTIAL HOUSING | OEM Genuine Part

Overview

The ZF 2052.209.109 DIFFERENTIAL HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part encloses the differential gear set, supporting the pinion and side gears while maintaining precise alignment under extreme torque loads. The SKU 2052.209.109 serves as the primary load-bearing shell that distributes power from the transmission output to the axle shafts. It integrates directly with the 2094101012: TRANSMISSION HOUSING to form the complete drivetrain enclosure, ensuring that lubricant stays contained and gear meshing remains accurate during demanding excavation and earthmoving operations.

Symptoms of Failure

When the ZF 2052.209.109 differential housing deteriorates, operators often notice oil seepage around the axle tube mounting flange, a common long-tail search query for construction equipment leaks. Another frequent symptom is excessive gear whine or howling during turns, indicating that the housing has warped or cracked, altering differential gear backlash. You may also observe metallic debris in the transmission fluid as the housing’s internal bearing bores wear, allowing the carrier to shift. Finally, intermittent wheel lockup or uneven power delivery can occur when the housing’s mounting ears fracture, causing the differential assembly to misalign within the 2094301036: HOUSING.

Technical Specifications

Compatibility

This differential housing is engineered for ZF’s WG series powershift transmissions commonly deployed in wheel loaders and graders. It directly fits the ZF WG180 and ZF WG200 transmission models, as well as the ZF WG210 series used in larger articulated trucks. The housing also appears in select ZF 4WG-200 and ZF 6WG-250 drivelines. For proper sealing, pair this unit with the 2094301071: COVER and the 2094298057: HOUSING to complete the differential carrier assembly. Always verify your transmission serial number against ZF’s parts catalog before installation.
