Overview
This genuine ZF 0730.109.582 WASHER is a precision-engineered thrust washer designed to manage axial loads and maintain critical clearances within ZF construction machinery transmissions. Positioned between rotating shafts and stationary housings, this OEM part prevents metal-to-metal contact and ensures smooth power flow. The SKU 0730.109.582 is frequently replaced during a full transmission rebuild to restore factory tolerances. When installed alongside a 2094104412: MAIN SHAFT or a 2094304054: MAIN SHAFT, this washer ensures the entire gear train operates without excessive end-play.
Symptoms of Failure
- Transmission oil leaks at the shaft seal: A worn 0730.109.582 washer allows axial shaft movement, which distorts the seal lip and causes hydraulic fluid to weep from the housing.
- Gear engagement slipping under load: When this washer loses its original thickness, the main shaft shifts position, preventing full clutch pack engagement and causing intermittent slipping.
- Metallic grinding noise during shifting: As the washer surface wears, hardened steel particles contaminate the oil, leading to audible grinding when the 2094106010: SHIFT SYSTEM attempts to engage gears.
- Excessive axial play in the driveline: Measurable back-and-forth movement at the output flange indicates the washer has compressed beyond its service limit.

Compatibility
This washer is a standard component in ZF WG180, WG200, and WG210 series powershift transmissions commonly used in wheel loaders, bulldozers, and telehandlers. It also appears in certain ZF 4WG-200 and 6WG-200 variants. Always verify fitment by cross-referencing the SKU 0730.109.582 against your transmission’s parts manual. For complete shaft assemblies, pair this washer with a 2094206001: GEARSHIFT SHAFT to ensure proper shift fork alignment.

Frequently Asked Questions
Q: Can I reuse the 0730.109.582 washer during a rebuild?
No. This washer is a single-use component that deforms under torque. Always install a new OEM washer to maintain correct shaft end-play and prevent premature seal failure.
Q: How do I know if this washer fits my ZF WG200 transmission?
Check the transmission serial number plate. The 0730.109.582 is used in WG200 series with main shaft part numbers 2094104412 or 2094304054. If your unit uses a different main shaft, verify the washer inner diameter matches your shaft journal.
Q: What torque should I apply to the retaining nut when installing this washer?
Refer to the ZF service manual for your specific model. Typical torque for the main shaft nut is 180-220 Nm, but always use a new 0630513070: SNAP RING to lock the assembly.
