ZF 4646.199.018 LOOSE PARTS for WG250 | OEM Genuine Part

Overview

The ZF 4646.199.018 LOOSE PARTS kit is a critical service component engineered specifically for the WG 250 Series transmission. This genuine OEM assembly contains the essential loose hardware required to secure and align internal clutch packs and shaft assemblies within the gear train. As a designated maintenance set, SKU 4646.199.018 replaces worn fasteners and spacers that degrade over time, ensuring the precise axial clearance necessary for smooth power flow. When paired with a new TRANSMISSION HOUSING, this kit restores the structural integrity of the entire unit.

Symptoms of Failure

When the components within the 4646.199.018 kit begin to fail, operators often report intermittent gear slippage under load, particularly during upshifts in the 3rd and 4th gear ranges. Another common symptom is abnormal metallic rattling from the bell housing at idle, indicating loose fasteners. Technicians frequently diagnose erratic shift timing caused by insufficient clamping force on the clutch drum. Finally, visible oil seepage around the PTO cover suggests that the included seals or spacers have fatigued, requiring immediate replacement of this loose parts set.

Technical Specifications

Compatibility

This genuine loose parts kit is primarily validated for the ZF WG 250 series. It also cross-fits the WG 180, WG 200, and WG 240 transmissions where the internal clutch housing geometry matches. For installations involving a HOUSING or COVER from the same generation, always verify the bolt pattern against the HEXAGON SCREW specifications to ensure proper thread engagement.
