ZF 4699.307.008 TORQUE SUPPORT | OEM Genuine Part

Overview

The ZF 4699.307.008 TORQUE SUPPORT is a critical structural component engineered to absorb and redirect torsional forces generated within the transmission assembly. Positioned between the main gear housing and the bell housing, this OEM genuine part ensures that rotational stress does not misalign internal shafts or bearings. The SKU 4699.307.008 is precision-machined to maintain exacting tolerances, preventing driveline vibration and extending the service life of adjacent components. Without this torque support, the transmission casing can flex under heavy load, leading to premature wear on gears and seals.

Symptoms of Failure

• Transmission housing cracking near mounting points: A worn or fatigued torque support allows excessive movement, causing stress fractures in the 4699101045 HOUSING.
• Progressive gear slipping under load: When the torque support loses rigidity, the input shaft can shift slightly, reducing gear mesh depth and causing intermittent slipping.
• Abnormal low-frequency vibration at idle: A compromised torque support fails to dampen harmonic oscillations, transmitting vibration through the chassis.
• Oil seepage from the bell housing joint: Misalignment caused by a failing support can distort the 4699301085 COVER seal surface, leading to fluid leaks.

Technical Specifications

Compatibility

This torque support is designed for ZF heavy-duty powershift transmissions used in construction machinery. It is a direct fit for the WG180 and WG200 series, as well as the WG150 and WG250 variants. The part interfaces with the 4699301108 HOUSING and the 4699301014 THREAD PROTECTIVE SHIELD to secure the assembly. Always verify your transmission serial number against the ZF parts catalog before installation.
