ZF 6057.018.129 for WG190 | OEM Genuine Part

Overview

The ZF 6057.018.129 is a precision-engineered component specifically designed for the WG 190 Series transmission. This OEM genuine part serves as a critical interface within the gearbox assembly, ensuring proper alignment and secure mounting of internal hydraulic and mechanical systems. The SKU 6057.018.129 is manufactured to ZF’s exacting tolerances, providing a direct replacement that restores factory performance. It is typically positioned between the main casing and the rear housing sections, acting as a structural support that maintains oil flow channels and gear train stability under heavy load conditions.

Symptoms of Failure

• Oil seepage at the rear of the transmission: When the ZF 6057.018.129 wears or cracks, pressurized transmission fluid can escape, leading to low fluid levels and potential overheating. This is a common long-tail search query for “ZF WG190 rear oil leak repair.”
• Intermittent gear engagement hesitation: A compromised 6057.018.129 can cause misalignment of the valve body or clutch pack, resulting in delayed or harsh shifting, especially when the transmission is hot.
• Unusual metallic rattling from the bell housing area: If the part fractures, loose fragments can rattle inside the transmission, indicating internal structural failure that requires immediate attention.
• Progressive loss of drive in higher gears: As the component degrades, hydraulic pressure drops, causing the transmission to slip or fail to hold gear ratios under load.

Technical Specifications

Compatibility

This OEM genuine part is primarily designed for the WG 190 Series transmission family. Based on its structural role, it is also compatible with the WG 180, WG 200, and WG 210 series transmissions that share the same rear housing interface. It is commonly used in off-highway vehicles, industrial loaders, and heavy-duty trucks where the WG platform is deployed. Always verify your transmission model number before ordering.

This part integrates directly with the TRANSMISSION HOUSING (4657101082) to form the main structural envelope. It also mounts to the HOUS.FRONT SECT (4657201166) and the HOUSING REAR PART (4657201170) to complete the assembly. For full rear section integrity, the HOUSING REAR SECTION (4657298102) is also required.

Q: How do I know if the ZF 6057.018.129 is the correct part for my WG190?
A: Check the stamped part number on the original component. The 6057.018.129 is specific to the WG190 series and will have matching bolt hole patterns and sealing grooves. If your transmission is a WG180 or WG200, verify the rear housing dimensions are identical.

Q: Can I install this part without replacing the gaskets or seals?
A: No. ZF recommends replacing all associated seals and gaskets when installing the 6057.018.129. We suggest also inspecting the SCREEN SHEET (4657301032) for debris during the repair.

Q: What torque specification should I use for the cap screws?
A: For the CAP SCREW (0636100803) used with this part, ZF specifies 45 Nm with a 90-degree angle tighten. Always use a torque wrench to avoid housing distortion.
