Overview
The ZF 0501.317.472 SPRING is a precision-engineered component designed for the internal clutch and shift assemblies of the WG100, WG130, and WG131 transmission series. This OEM genuine part provides the necessary preload and return force for critical valve bodies and actuator pistons, ensuring smooth gear engagement and consistent hydraulic pressure. The SKU 0501.317.472 is manufactured to exact ZF tolerances, making it a direct replacement for worn springs that compromise shift quality. It works in concert with the 5838109009: DIFFERENTIAL to maintain proper load distribution within the gear train.
Symptoms of Failure
- Delayed or harsh shifting – A fatigued 0501.317.472 spring can cause sluggish engagement between gears, leading to noticeable jerking or hesitation during acceleration.
- Intermittent gear slippage under load – When the spring loses its tension, the clutch pack may not fully engage, resulting in temporary power loss on inclines or during heavy towing.
- Hydraulic pressure fluctuations – A worn spring in the valve body can cause erratic oil pressure, triggering warning lights or erratic transmission behavior at low speeds.
- Unusual metallic rattling from the transmission housing – A broken or weakened spring may allow loose components to vibrate, producing a distinct noise that worsens in neutral.

Compatibility
This spring is specifically validated for the ZF WG100, WG130, and WG131 series transmissions. It is also compatible with the WG180 and WG200 models when used in the shift valve assembly. For optimal performance, always pair this spring with a properly torqued 0750117075: TAPER ROLLER BEARING and inspect the 2093209023: DIFFERENTIAL for wear during rebuilds. The spring also interfaces with the 5838300626: DIFFERENTIAL HOUSING to maintain proper alignment of internal components.

Frequently Asked Questions
Q: Can I reuse the old spring if it looks intact?
A: No. ZF springs lose tension over time due to metal fatigue. Always replace the 0501.317.472 spring during any transmission overhaul to prevent premature failure of the shift assembly.
Q: Does this spring fit the ZF WG180 transmission?
A: Yes, it is compatible with WG180 and WG200 models when used in the main shift valve body. Verify your transmission’s part number against the OEM catalog before installation.
Q: What tools are needed to install this spring?
A: A spring compressor tool and a torque wrench are required. Ensure the 0631329088: SPRING PIN is also replaced to guarantee proper retention.
