ZF 0730.104.240 WASHER | OEM Genuine Part

Overview

The ZF 0730.104.240 WASHER is a precision-engineered OEM genuine component designed to maintain critical sealing pressure and axial clearance within ZF heavy-duty transmission assemblies. This hardened steel washer sits between the transmission housing and clutch piston assembly, acting as a load-distributing shim that prevents metal-to-metal contact and ensures proper hydraulic circuit integrity. The SKU 0730.104.240 is commonly found in construction machinery transmissions where vibration and thermal cycling demand exact dimensional stability. When installed alongside the 4143101009 HOUSING and 4143301025 HOUSING, this washer forms a leak-proof interface that supports consistent oil flow to clutch packs.

Symptoms of Failure

• Hydraulic oil seepage at housing mating surfaces – A worn 0730.104.240 washer loses its crush tolerance, allowing pressurized ATF to escape between the 4143101009 HOUSING and adjacent components, often visible as dark streaks on the transmission exterior.
• Intermittent gear slippage under load – When the washer flattens beyond specification, clutch piston stroke becomes insufficient, causing delayed engagement or momentary power loss during excavation or grading operations.
• Metallic debris in transmission oil pan – A fractured washer sheds fine steel particles into the hydraulic circuit, accelerating wear on the 0634313603 O-RING and valve body components.
• Abnormal transmission housing temperature – Reduced clearance from washer collapse creates friction between rotating assemblies, generating localized heat that can warp adjacent 4475280018 SCREW PLUG sealing surfaces.

Technical Specifications

Compatibility

This washer is engineered for ZF WG series powershift transmissions commonly used in wheel loaders, graders, and excavators. It directly fits the WG180, WG200, and WG211 models where it functions as a clutch pack shim. The 0730.104.240 also appears in certain ZF Ecomat 4HP and 5HP series transmissions used in construction machinery. Always verify fitment by cross-referencing your transmission serial number with the 4143298457 SEAL KIT specifications, as housing variations may require different washer thicknesses.
