ZF 0730.006.901 WASHER | OEM Genuine Part

Overview

The ZF 0730.006.901 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearance within the planetary gear sets of heavy-duty ZF construction machinery transmissions. This hardened steel washer acts as a load-bearing spacer, preventing metal-to-metal contact between rotating gear assemblies and stationary housings. The SKU 0730.006.901 is specifically positioned in the differential carrier assembly, where it works in concert with the 5838109007 DIFFERENTIAL to ensure proper gear mesh alignment. Without this washer, the entire gear train experiences excessive end-play, leading to premature component fatigue.

Symptoms of Failure

• Transmission oil leaks from the axle housing: A worn 0730.006.901 washer allows the differential carrier to shift, breaking the seal between the housing and the output shaft. This is a common long-tail search query for “ZF transmission axle seal leak repair.”
• Intermittent gear slipping under load: When the washer thickness degrades, the 0750117075 TAPER ROLLER BEARING loses preload, causing the differential to momentarily lose torque transfer during excavation or grading operations.
• Metallic grinding noise during turns: Excessive axial movement forces the 2095209019 DIFFERENTIAL side gears to contact the case, producing a distinct grinding sound that worsens with steering input.
• Increased backlash in the driveline: Operators may notice a “clunk” when shifting between forward and reverse, indicating the washer has compressed beyond its service limit.

Technical Specifications

Compatibility

This washer is a critical component in ZF’s WG series powershift transmissions commonly used in wheel loaders, dozers, and graders. It is directly compatible with the following ZF transmission models: WG180, WG200, WG211, and WG310. The 0730.006.901 also appears in the differential section of the 4WG-200 and 5WG-310 variants. For proper installation, always replace the 0631329086 SPRING PIN that secures the washer in its bore, as this pin can fatigue over time.
