Overview
The ZF 4616.262.004 STATOR is a critical hydraulic torque converter component engineered specifically for the WG65 series of powershift transmissions. Positioned between the pump and turbine within the converter assembly, this OEM genuine part redirects fluid flow to multiply engine torque during low-speed operation. The SKU 4616.262.004 ensures precise oil routing to maintain optimal converter efficiency and heat dissipation. When paired with a robust TRANSMISSION HOUSING, this stator forms the backbone of reliable power delivery in heavy-duty industrial applications.
Symptoms of Failure
- Torque converter shudder at low RPM: A worn 4616.262.004 stator fails to redirect oil correctly, causing noticeable vibration during vehicle launch or under load.
- Overheating transmission fluid: When the stator vanes degrade, fluid recirculation is compromised, leading to persistent high operating temperatures and potential seal damage.
- Delayed or harsh gear engagement: Loss of stator lock-up function results in sluggish acceleration and abrupt shifts, particularly in stop-and-go operations.
- Metallic debris in transmission pan: Fragments from a failing stator often contaminate the fluid, accelerating wear on adjacent components like the HEXAGON SCREW fasteners.
