ZF 0730.307.803 TYPE PLATE | OEM Genuine Part

Overview

The ZF 0730.307.803 TYPE PLATE is a critical identification and sealing component mounted on the exterior of ZF heavy-duty transmissions. This OEM genuine part provides essential transmission model data, serial numbers, and specification markings for construction machinery applications. The plate sits flush against the transmission housing, serving both as a permanent identification marker and as a sealing interface to prevent contamination ingress. The SKU 0730.307.803 is laser-etched with ZF specifications, ensuring traceability for maintenance crews and rebuild shops working on WG-series transmissions.

Symptoms of Failure

• Illegible transmission identification — When the TYPE PLATE corrodes or delaminates, critical model numbers become unreadable, complicating parts ordering and rebuild procedures.
• Oil seepage around the plate perimeter — A warped or cracked 0730.307.803 plate allows transmission fluid to weep past the mounting surface, leaving oily residue on the 4143101025 HOUSING.
• Loose or rattling plate — Vibration fatigue can break the retaining 0631329135 SPRING PIN, causing the TYPE PLATE to shift and potentially damage adjacent components.
• Misdiagnosis during troubleshooting — A missing or damaged plate leads to incorrect transmission identification, resulting in wrong replacement parts being ordered for the assembly.

Technical Specifications

Compatibility

This TYPE PLATE is designed for ZF WG-series powershift transmissions commonly found in construction machinery. It fits the WG180, WG200, and WG250 models, as well as the ERGOPOWER series used in wheel loaders and graders. The plate mounts directly onto the 4143301055 HOUSING and aligns with the 4143298040 CASE for proper sealing. Always verify the plate orientation against your transmission serial number prefix before installation.
