Overview
The ZF 0730.004.826 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 series transmission. This hardened steel washer serves as a critical load-spreading and axial positioning element within the planetary gearset assembly, ensuring correct clearance between rotating and stationary components. The SKU 0730.004.826 is manufactured to ZF’s exacting tolerances, providing a reliable sealing surface and preventing metal-on-metal contact that can lead to premature gear wear. When installed alongside the 4460165051 CONSOLE and the 4460368311 CONSOLE, this washer maintains the structural integrity of the clutch pack assembly.
Symptoms of Failure
- Transmission fluid seepage at the output flange: A worn 0730.004.826 washer can compromise the sealing interface, causing slow oil leaks that leave drips under the vehicle after extended parking.
- Gear engagement hesitation or slipping: When the washer loses its original thickness, axial play increases, leading to delayed clutch pack engagement and intermittent power loss during acceleration.
- Metallic grinding noise during gear shifts: A fatigued washer allows internal components to contact each other, producing a distinct grinding sound, particularly when shifting between 2nd and 3rd gear.
- Increased end-play in the main shaft: Excessive axial movement detected during routine maintenance indicates the washer has compressed beyond its service limit, requiring immediate replacement.
