ZF 6073.015.523 for WG190 | OEM Genuine Part

Overview

This genuine ZF 6073.015.523 component is a critical internal assembly part engineered specifically for the WG 190 Series transmission. Designed to manage precise hydraulic flow and mechanical engagement within the gear train, this OEM part ensures consistent torque delivery and shift quality under heavy-duty industrial loads. The SKU 6073.015.523 interfaces directly with the main casing and valve body to regulate pressure distribution, making it indispensable for maintaining transmission integrity. When paired with a robust TRANSMISSION HOUSING, this part forms the backbone of reliable power transmission in construction and agricultural machinery.

Symptoms of Failure

• Delayed or harsh gear engagement — Worn 6073.015.523 components cause inconsistent hydraulic pressure, leading to noticeable lag or jarring shifts during acceleration.
• Internal transmission fluid leaks — Degraded sealing surfaces around this part result in visible oil seepage near the bell housing or mid-case, often accompanied by a burnt smell.
• Erratic shift patterns under load — When this part fails, operators report unexpected downshifting or slipping in higher gears, particularly when towing or climbing grades.
• Increased operating noise — A whining or grinding sound from the transmission center section indicates wear in the 6073.015.523 assembly, often worsening as fluid temperature rises.

Technical Specifications

Compatibility

This genuine ZF 6073.015.523 part is primarily designed for the WG 190 Series transmission family. It is also compatible with the WG180 and WG200 series models that share the same hydraulic control architecture. For optimal fitment, verify that your transmission housing matches the mounting pattern of the HOUS.FRONT SECT and the HOUSING REAR PART. In applications requiring a full rebuild, the HOUSING REAR SECTION must also be inspected for wear to ensure proper alignment of the 6073.015.523 assembly.

Frequently Asked Questions

Q: How do I know if the 6073.015.523 part needs replacement?
A: Look for persistent fluid leaks around the transmission mid-section, delayed shifts when cold, or a gradual loss of power during uphill operation. A diagnostic pressure test showing below-spec readings at the valve body often confirms wear in this assembly.

Q: Can I install this part without replacing the housing sections?
A: While direct replacement is possible, we strongly recommend inspecting the HOUS.FRONT SECT and HOUSING REAR PART for scoring or distortion. Worn housing bores will accelerate failure of the new 6073.015.523 component.

Q: What is the typical service life of this OEM part?
A: In normal industrial applications with proper fluid maintenance, the 6073.015.523 lasts 4,000–6,000 operating hours. Severe duty cycles or contaminated fluid can reduce this to 2,500 hours or less.
