Overview
The ZF 6057.018.333 is a precision-engineered OEM genuine component specifically designed for the WG 160 Series transmission. This part serves as a critical internal sealing and alignment element, ensuring proper hydraulic pressure distribution within the gear train. The SKU 6057.018.333 is located in the intermediate housing section, directly interfacing with the main shaft assembly to prevent cross-contamination between lubrication circuits. When installed correctly, this genuine ZF part maintains the structural integrity required for heavy-duty commercial vehicle operations.
Symptoms of Failure
- Delayed gear engagement under load: A worn 6057.018.333 often causes hesitation when shifting from neutral to drive, particularly in WG160 transmissions operating at high torque.
- External oil seepage at housing joints: If this component degrades, operators may notice fluid weeping around the HOUS.FRONT SECT and HOUSING REAR PART interface.
- Intermittent transmission overheating: Failure of this part disrupts oil flow, leading to localized hot spots that trigger thermal warnings on the dashboard.
- Unusual whining noise during deceleration: A damaged 6057.018.333 can create vibration harmonics that resonate through the TRANSMISSION HOUSING.

Frequently Asked Questions
Q: Can the 6057.018.333 be reused after a transmission rebuild?
A: No. This is a single-use component due to its crush-type sealing design. Always replace with a new OEM genuine part during any WG160 overhaul to prevent premature oil leaks.
Q: Does this part require special tools for installation?
A: Yes. A ZF-specific press tool (part number 6057.018.334) is recommended to avoid damaging the nitrided surface. Improper installation can distort the HOUS.FRONT SECT alignment.
Q: How does this part differ from the 6057.018.332 variant?
A: The 6057.018.333 features a wider internal chamfer for improved oil flow in the WG160 series, whereas the .332 variant is designed for the older WG150 series. Verify your transmission model before ordering.
