ZF 0730.004.825 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.004.825 WASHER is a precision-engineered OEM genuine component designed specifically for the WG200 series transmission. This hardened steel washer functions as a critical load-spreading interface between fasteners and transmission housing surfaces, ensuring proper torque retention and preventing galling in high-stress bolted joints. Located within the transmission’s rear power take-off (PTO) or clutch housing assembly, the SKU 0730.004.825 maintains axial clearance and distributes clamping forces evenly during operation. When replacing this washer, always inspect the mating 4460165051 CONSOLE and 4460368311 CONSOLE for wear patterns, as these components work in tandem to maintain driveline alignment.

Symptoms of Failure

• Transmission oil seepage at bolt interfaces: A worn or crushed 0730.004.825 washer allows fastener loosening, creating micro-gaps that permit ATF to weep past sealing surfaces.
• Audible clicking or ticking from the PTO housing: When the washer loses its original thickness, axial play develops between the 0636011429 HEXAGON SCREW and housing, causing metallic contact noise under load.
• Intermittent gear engagement hesitation: Insufficient washer height alters the stack-up tolerance, affecting shift fork positioning and clutch pack clearance in the WG200.
• Visible fretting corrosion on bolt heads: A collapsed washer permits micro-movement, leaving orange-brown residue on the fastener and surrounding 0730100365 WASHER surfaces.

Technical Specifications

Compatibility

This OEM washer is engineered for the ZF WG200 series, including the WG180, WG200, and WG210 variants used in medium-duty trucks, buses, and construction equipment. It also fits select ZF Ecomat 4HP and 5HP transmissions where the same bolt pattern and torque specifications apply. For proper installation, always pair with a new 0636011429 HEXAGON SCREW to ensure correct clamping force. The 0730.004.825 is not interchangeable with standard metric washers due to its specific chamfer geometry and hardness rating.
