ZF 4616.330.009 RING for WG65 | OEM Genuine Part

Overview

The ZF 4616.330.009 RING is a precision-engineered internal component designed exclusively for the WG 65 Series transmission. This OEM genuine part functions as a critical sealing and spacing element within the planetary gear set, ensuring correct axial clearance and preventing fluid bypass between rotating assemblies. The SKU 4616.330.009 is manufactured to ZF’s exacting tolerances, making it essential for maintaining hydraulic pressure integrity. When installed alongside the 4616105415 OUTPUT and the 4616303144 OUTPUT FLANGE, this ring helps stabilize the driveline under heavy load conditions.

Symptoms of Failure

• Internal oil leaks and pressure loss: A worn 4616.330.009 ring allows transmission fluid to bypass the sealing surface, leading to sluggish shifting and delayed engagement.
• Gear slipping under load: When the ring loses its dimensional integrity, the clutch pack cannot maintain clamping force, causing the transmission to slip during acceleration.
• Metallic debris in the oil pan: As the ring wears against the 4616101094 TRANSMISSION HOUSING, fine metal particles contaminate the fluid, accelerating wear on other components.
• Abnormal whining or grinding noises: Excessive clearance from a degraded ring allows gear teeth to contact improperly, producing audible distress from the WG65 assembly.

Technical Specifications

Compatibility

This ring is a direct fit for the ZF WG 65 Series transmission family, including models such as the WG65, WG80, and WG90. It is also compatible with certain variants of the WG180 and WG200 series where the planetary carrier uses the same snap-ring groove dimensions. Always verify the 0636011038 HEXAGON SCREW torque specifications when reassembling the housing to avoid distorting the new ring.
