Overview
The ZF 0632.000.017 CUP SPRING is a precision-engineered component designed for the WG 200 Series automatic transmissions. This OEM genuine part functions as a critical load-bearing element within the clutch pack assembly, ensuring consistent spring tension for smooth gear engagement and disengagement. Located inside the transmission housing, the cup spring absorbs axial loads and maintains proper clearance between rotating elements. The SKU 0632.000.017 is manufactured to ZF’s exacting tolerances, making it essential for restoring factory-specified shift quality during a rebuild or overhaul. When paired with a robust TRANSMISSION HOUSING, this cup spring helps maintain structural integrity under high torque conditions.
Symptoms of Failure
When the ZF 0632.000.017 cup spring fatigues or cracks, operators often notice specific drivability issues. Look for these failure indicators:
- Delayed or harsh shifting: A worn cup spring cannot maintain proper clutch pack preload, causing hesitation between gears or abrupt engagement.
- Oil leaks near the bell housing: Loss of spring tension can misalign seals, leading to transmission fluid seepage around the TRANSMISSION HOUSING interface.
- Gear slipping under load: Insufficient spring force allows clutch plates to slip during acceleration, particularly in higher gears.
- Metallic rattling from the transmission: A broken cup spring can produce a distinct clicking or rattling noise during idle or low-speed operation.

Compatibility
This cup spring is primarily designed for the ZF WG 200 Series, including models WG200, WG210, and WG180. It also fits select variants of the ZF 6HP and 8HP automatic transmissions used in heavy-duty commercial vehicles. Always verify the part number against your transmission’s serial plate; the TYPE PLATE provides critical identification data. For secure mounting, use a GROOVED STUD to anchor the spring assembly within the clutch drum.
