Overview
The ZF 4468.353.053 FIXING PLATE (SKU: 4468.353.053) is a critical OEM genuine retention component engineered for heavy-duty construction machinery transmissions. This precision-machined plate functions as a locating and securing element within the planetary gearset assembly, ensuring that internal shafts and bearing races maintain correct axial alignment under extreme torque loads. By preventing unwanted lateral movement of adjacent components, the fixing plate directly supports the structural integrity of the differential housing and clutch pack stack. In a typical ZF transmission rebuild, this part is often replaced alongside a 5838109007: DIFFERENTIAL to guarantee proper end-play tolerances.
Symptoms of Failure
- Transmission case oil seepage near the PTO cover: A worn or cracked fixing plate can distort the sealing surface, allowing ATF to weep past the gasket. This is a common long-tail search query for “ZF transmission oil leak at fixing plate.”
- Intermittent gear engagement delay in forward gears: When the plate fatigues, it fails to hold the 0750117075: TAPER ROLLER BEARING in its proper race, causing momentary slippage during power shifts.
- Metallic rattling noise from the differential area: A loose fixing plate allows the 2095209019: DIFFERENTIAL assembly to shift axially, producing a distinct chatter under deceleration.
- Premature wear on the spring pin bore: The 0631329086: SPRING PIN that locks the plate in place can shear if the plate migrates, leading to catastrophic internal damage.

Compatibility
This fixing plate is primarily designed for ZF’s WG series powershift transmissions used in wheel loaders and graders. It is a direct fit for the WG180, WG200, and WG210 models. It also appears in certain 4WG200 and 6WG200 variants where the differential carrier assembly requires a secondary retention plate. Always verify the part number against your transmission’s serial number tag. When servicing these units, it is standard practice to inspect the 5838300817: THRUST WASHER and the 5838300682: DIFFERENTIAL AXLE for scoring, as they share the same lubrication circuit.
