ZF 0730.005.721 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.005.721 WASHER for WG200 is an OEM genuine sealing component engineered to maintain precise axial clearance and prevent fluid migration within the WG 200 series transmission assembly. Positioned between the output flange and the bearing race, this hardened steel washer ensures consistent clamping force when paired with the 0636011429 HEXAGON SCREW. As a critical load-distribution element, the SKU 0730.005.721 directly supports the structural integrity of the driveline connection, reducing vibration-induced wear on adjacent housings. Its factory-specified surface finish and dimensional tolerance are essential for maintaining the transmission’s internal hydraulic balance.

Symptoms of Failure

• Oil seepage at the output flange interface: A worn 0730.005.721 washer allows axial play, breaking the seal between the 4460168651 INPUT FLANGE and the bearing retainer, leading to visible drips under the vehicle.
• Gear engagement hesitation or slipping: Loss of correct washer thickness alters the preload on the planetary gear set, causing delayed clutch pack engagement under load.
• Abnormal driveline clunking during acceleration: Excessive clearance from a collapsed washer permits the 4460165051 CONSOLE to shift, producing metallic impact noises.
• Elevated operating temperatures: Friction from misaligned components due to washer failure generates excess heat, detectable through transmission fluid discoloration.

Technical Specifications

Compatibility

This washer is specifically validated for the ZF WG200 series, including the WG200, WG210, and WG180 variants used in medium-duty trucks and construction equipment. It also fits select WG150 applications where the output shaft diameter matches 58.5 mm. For installations requiring the 4460368311 CONSOLE, always verify the washer’s thickness against the service manual to avoid over-torquing the 0730100365 WASHER stack. The 0730.005.721 is not interchangeable with earlier WG120 series flat washers due to differing load ratings.
