Overview
The ZF 4616.301.126 INTERMEDIATE RING is a precision-engineered spacer component designed for the WG 65 Series transmission. This OEM genuine part sits between the planetary gear set and the output shaft assembly, ensuring correct axial clearance and load distribution during high-torque operations. The SKU 4616.301.126 acts as a critical interface element, preventing metal-on-metal contact between rotating assemblies. When paired with a properly torqued 0636011038 HEXAGON SCREW, this ring maintains the structural integrity of the gear train under heavy-duty conditions.
Symptoms of Failure
- Transmission oil leaks at the output housing: A worn intermediate ring can cause misalignment, leading to seal failure and fluid seepage around the 4616105413 OUTPUT assembly.
- Gear slipping under load: Excessive axial play from a degraded ring reduces clutch pack engagement, particularly during uphill or loaded starts.
- Metallic grinding noise during shifting: As the ring wears, the 4616203017 OUTPUT FLANGE may contact the housing, producing audible scraping sounds.
- Vibration in neutral or drive: Loss of ring thickness creates imbalance, transmitting vibration through the 4616101117 TRANSMISSION HOUSING.
