ZF 0730.000.874 WASHER for WG65 | OEM Genuine Part

Overview

The ZF 0730.000.874 WASHER is a precision-engineered OEM genuine component specifically designed for the WG 65 Series transmission. This hardened steel washer functions as a critical load-spreading interface between fasteners and the transmission housing assembly, ensuring even torque distribution and preventing galling or deformation under high-stress operating conditions. Installed internally within the gearbox, the SKU 0730.000.874 directly interfaces with the TRANSMISSION HOUSING and the HOUSING to maintain precise axial clearances. This genuine ZF part guarantees metallurgical consistency and dimensional accuracy that aftermarket alternatives cannot replicate, directly impacting the longevity of your transmission rebuild.

Symptoms of Failure

• Transmission oil seepage at fastener points: A worn or crushed 0730.000.874 washer loses its clamping force, allowing fluid to migrate past the SCREW PLUG and housing interface, leading to visible drips under the bell housing.
• Audible gear rattle or loose mounting: When the washer fatigues, fasteners can back off incrementally, causing the TRANSMISSION HOUSING to vibrate against mating surfaces, producing a distinct metallic chatter during gear engagement.
• Inaccurate oil level readings: Deformation of this washer alters the seating depth of the OIL LEVEL GAGE, leading to chronic overfilling or underfilling that accelerates bearing wear and gear slipping.
• Progressive torque loss on housing bolts: Operators may notice fasteners requiring frequent retorquing during routine maintenance intervals, a clear indicator the washer has exceeded its elastic limit.

Technical Specifications

Compatibility

While the 0730.000.874 WASHER is cataloged primarily for the WG 65 Series, its dimensional profile and load rating make it applicable across the broader ZF WG family. Compatible transmission models include the WG180, WG200, WG120, and WG150 series, particularly in applications where the washer is used in conjunction with the COVER and HEXAGON SCREW assemblies. It is also frequently specified for the WG 80 and WG 100 variants when replacing the SCREW PLUG or SEALING RING during a full gasket overhaul. Always verify the washer thickness against your specific housing stack-up, as the TYPE PLATE on the INTERM.GEARBOX may indicate alternative shim requirements.
