ZF 4644.183.069 LOOSE PARTS for WG200 | OEM Genuine Part

Overview

The ZF 4644.183.069 LOOSE PARTS kit is a critical service component designed for the WG 200 series transmissions. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies within the transmission housing. Specifically, it interfaces with the TRANSMISSION HOUSING to ensure proper alignment of the clutch packs and planetary gear sets. The SKU 4644.183.069 is factory-sealed and engineered to restore original clamping forces and vibration resistance during a rebuild or major repair.

Symptoms of Failure

• Oil leaks at the housing seam: Worn or missing loose parts can cause the TRANSMISSION HOUSING joint to separate under pressure, leading to visible fluid seepage.
• Gear slipping under load: If the fasteners in this kit lose torque, internal components shift, causing intermittent clutch engagement and power loss.
• Abnormal driveline noise: Loose retaining elements allow the OUTPUT FLANGE to wobble, producing a rhythmic clunking sound during acceleration.
• Hard shifting or delayed engagement: Misalignment from degraded loose parts affects hydraulic pressure distribution, resulting in harsh or delayed gear changes.

Technical Specifications

Compatibility

This loose parts kit is primarily designed for the WG 200 series, but it also fits the WG 180 and WG 210 variants due to shared housing bolt patterns. It is essential for securing the DISCONNECTION assembly and the OUTPUT FLANGE in all WG-series transmissions produced after 2015. Always verify the TRANSMISSION HOUSING casting number before installation.
