ZF 0730.005.723 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.005.723 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 series transmission family. This hardened steel washer functions as a critical load-spreading element between the transmission housing and the rotating assembly, ensuring correct axial clearance and preventing fretting wear on mating surfaces. As an integral part of the gear train support structure, the SKU 0730.005.723 sits within the output shaft area, where it maintains proper preload on adjacent bearings and gears. Using this genuine ZF part guarantees factory-specified tolerances, which aftermarket alternatives often fail to replicate, leading to premature drivetrain degradation.

Symptoms of Failure

• Transmission oil seepage at the output flange: When the 0730.005.723 washer loses its flatness or develops surface pitting, the seal interface becomes compromised, allowing ATF to weep past the output shaft seal.
• Audible gear rattle during coast-down: A worn washer reduces axial preload, permitting excessive end-play in the gear cluster that manifests as a metallic chatter when the vehicle decelerates without throttle.
• Vibration in the driveline under load: As the washer thickness degrades from compression fatigue, the entire output assembly shifts out of alignment, creating low-frequency vibrations that intensify during acceleration.
• Hard shifting or delayed engagement: Insufficient washer height alters the stack-up tolerances, which can cause the clutch packs to engage at incorrect depths, resulting in harsh or delayed gear changes.

Technical Specifications

Compatibility

This washer is engineered for the ZF WG 200 series, including the WG180, WG200, and WG210 transmission models. It is also used in select ZF 4HP20 and 5HP24 variants that share the same output shaft architecture. Always verify your transmission serial number before installation, as early WG200 units may require a different shim stack configuration.

Installation Context

During a full rebuild of the WG200 output section, this washer is typically replaced alongside the 4460165051 CONSOLE and the 4460368311 CONSOLE, which together form the bearing support cradle. The assembly is secured using the 0636011429 HEXAGON SCREW, torqued to factory specifications. For the opposite side of the shaft, the 0730100365 WASHER provides complementary spacing. Always inspect the mating surfaces of the 4460168651 INPUT FLANGE for scoring before reassembly.
