Overview
The ZF 3035.304.006 LOCKING PLATE is a critical retention component engineered specifically for the WG 65 Series transmission. This OEM genuine part functions as a mechanical stop that secures the output shaft assembly within the gear train, preventing axial movement during high-torque operations. Positioned directly adjacent to the 4616105402: OUTPUT and the 4005303005: OUTPUT FLANGE, the locking plate ensures that the entire driveline remains rigidly aligned. The SKU 3035.304.006 is machined to exact OEM tolerances, making it a non-negotiable element for maintaining gear mesh integrity in heavy-duty industrial applications.
Symptoms of Failure
- Audible gear clatter under load: A worn locking plate allows micro-movement in the output shaft, producing a distinct metallic knocking sound during acceleration or deceleration.
- Premature output flange wear: When the 3035.304.006 loses its locking tension, the 4005303005: OUTPUT FLANGE can develop uneven contact patterns, leading to vibration and accelerated spline degradation.
- Transmission oil seepage near the rear housing: A deformed locking plate compromises the seal between the 4616101119: TRANSMISSION HOUSING and the output assembly, often resulting in slow drips of ATF fluid.
- Difficulty engaging or holding gear ratios: Excessive axial play from a failed plate can mimic symptoms of clutch pack failure, causing intermittent slipping in higher gears.

Compatibility
This locking plate is a direct-fit component for the ZF WG 65 Series transmission family. It is also compatible with the following ZF models that share the same output shaft architecture: WG180, WG200, WG250, and WG300. The 3035.304.006 interfaces directly with the 4616105402: OUTPUT shaft and is secured using the 0636011038: HEXAGON SCREW to prevent rotational loosening. Always verify the transmission serial number against the OEM parts catalog before installation.
