ZF 0730.111.776 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.111.776 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 series transmission. This hardened steel washer functions as a critical load-spreading element between rotating assemblies and stationary housings within the planetary gear set. Positioned adjacent to the 4460115043 HOUSING, it maintains proper axial clearance and prevents metal-on-metal contact under high torque conditions. The SKU 0730.111.776 ensures exact fitment and material hardness specifications required for reliable long-haul operation.

Symptoms of Failure

• Transmission oil seepage at housing interface — A worn 0730.111.776 washer can distort, allowing lubricant to bypass the 4469315012 AXLE DRIVE HOUSING seal surface.
• Audible gear rattle during coast-down — Excessive axial play from a collapsed washer causes planetary gears to chatter against the 0750117406 TAPER ROLLER BEARING race.
• Intermittent gear slipping under load — Loss of preload from a fatigued washer reduces clutch pack clamping force, leading to torque loss.
• Metallic debris in transmission fluid — A fractured washer sheds particles that accelerate wear on the 0750117802 TAPERED ROLLER BEARING.

Technical Specifications

Compatibility

This washer is engineered for the ZF WG 200 series transmissions, including models WG180, WG200, and WG210. It also fits select WG 150 variants where the planetary carrier assembly uses the same 42.5 mm shaft bore. Always verify the 0734319337 SHAFT SEAL condition when replacing this washer, as seal lip wear often accompanies washer fatigue. For earlier WG 180 builds, cross-reference with 0730161317 WASHER for dimensional confirmation.
