ZF 4644.103.452 OUTPUT for WG180 | OEM Genuine Part

Overview

The ZF 4644.103.452 OUTPUT for WG180 is a critical driveline component engineered to transfer torque from the transmission’s planetary gearset to the output flange. Positioned at the rear of the WG 180 series housing, this OEM genuine part ensures precise rotational alignment and load distribution under heavy-duty cycles. The SKU 4644.103.452 interfaces directly with the TRANSMISSION HOUSING and the HOUSING to maintain concentricity, while the TYPE PLATE provides essential identification for service matching. Manufactured to ZF’s original tolerances, this output shaft assembly is designed for long service intervals in construction and material handling equipment.

Symptoms of Failure

• Oil leaks at the rear seal area — Worn splines or bearing journals on the 4644.103.452 can cause seal misalignment, leading to fluid seepage around the output flange.
• Gear slipping under load — Excessive backlash from a fatigued output shaft results in intermittent power loss, especially during uphill travel or heavy lifting.
• Vibration or driveline shudder — A damaged output component creates harmonic imbalance, felt as a low-frequency rumble through the chassis at operating speeds.
• Metallic debris in transmission fluid — Flaking or spalling on the output shaft surface introduces ferrous particles into the sump, accelerating wear on the GROOVED STUD and adjacent bearings.

Technical Specifications

Compatibility

This output component is primarily designed for the ZF WG 180 series transmissions, commonly found in wheel loaders, telehandlers, and industrial forklifts. It also fits select WG 200 variants where the output flange interface and spline count match. The 4644.103.452 is not interchangeable with earlier WG 150 or later WG 250 series without adapter modifications. Always verify the TYPE PLATE on your transmission housing to confirm model revision before installation.
