ZF 5838.300.398 BRACKET | OEM Genuine Part

Overview

The ZF 5838.300.398 BRACKET is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part serves as the primary mounting interface, securing the axle housing and differential assembly to the transmission casing. Engineered to withstand extreme torsional loads and vibration, the bracket ensures precise alignment of rotating components. The SKU 5838.300.398 is specifically designed to maintain the geometric integrity of the drivetrain, preventing misalignment that can lead to premature wear on adjacent assemblies such as the 5838022003: REAR AXLE and the 5838109001: DIFFERENTIAL.

Symptoms of Failure

• Transmission housing oil seepage: A cracked or warped bracket often causes the gasket surface to fail, leading to slow oil leaks around the rear axle interface. This is a common long-tail search query for “ZF transmission bracket oil leak repair.”
• Abnormal gear whine from differential area: When the bracket loses its structural rigidity, the 0750117075: TAPER ROLLER BEARING can shift out of its preload tolerance, producing a distinct whining noise during load cycles.
• Vibration during low-speed maneuvering: A fatigued bracket allows the 5838300128: DIFFERENTIAL HOUSING to oscillate, causing noticeable chassis vibration when operating in first or reverse gear.
• Bolt hole elongation or cracking: Visual inspection often reveals stress fractures around the mounting points, which can lead to sudden driveline separation if not addressed.

Technical Specifications

Compatibility

This bracket is engineered for ZF’s WG series powershift transmissions commonly deployed in wheel loaders and graders. It is a direct fit for the WG180 and WG200 models, as well as the WG211 series used in articulated dump trucks. The part also interfaces with select WG310 variants when paired with the correct differential housing. Always verify the casting number on your existing bracket before ordering.
