Overview
The ZF 0501.316.599 CLIP (SKU: 0501.316.599) is a critical retention component used within the clutch pack assembly of heavy-duty ZF transmissions. This genuine OEM part secures the piston and spring assemblies in place, preventing axial movement during high-torque operations. Typically found in the hydraulic control circuit of construction machinery transmissions, this clip ensures that the 0501211694: MOTOR maintains consistent pressure against the clutch plates. Without this clip, the entire shift sequence becomes unstable, leading to premature wear on surrounding components.
Symptoms of Failure
- Transmission oil leaks near the clutch housing: A worn or broken clip allows the piston seal to shift, causing pressurized fluid to escape past the 0501314793: COVER.
- Intermittent gear slipping under load: When the clip fatigues, the 0501314799: BUSH can dislocate, reducing clamping force on the clutch pack.
- Delayed engagement or harsh shifting: A deformed clip prevents the 4108101140: HOUSING from maintaining proper alignment, leading to erratic hydraulic response.
- Metallic rattling from the transmission bell housing: A loose clip can vibrate against the drum, creating noise and debris that contaminates the oil.

Compatibility
This clip is engineered for ZF power shift transmissions commonly used in wheel loaders, excavators, and dozers. It is a direct fit for the following models: WG180, WG200, WG210, and WG240 series. It also applies to the 4WG-180 and 4WG-200 variants where the clutch pack uses a retaining ring design. Always verify the snap ring groove diameter in your 4108101140: HOUSING before installation.
