ZF 4642.199.776 LOOSE PARTS for WG150 | OEM Genuine Part

Overview

The ZF 4642.199.776 LOOSE PARTS set is a critical OEM genuine component designed for the WG 150 transmission series. This kit consolidates essential hardware and small fittings required to secure and seal internal assemblies within the gearbox. As a loose parts package, it ensures that all fasteners, washers, and retaining elements are replaced simultaneously during a major overhaul, preventing premature wear from reused hardware. The SKU 4642.199.776 is specifically engineered to match ZF’s original tolerances, making it indispensable for maintaining the structural integrity of the transmission housing. When paired with a new 4642101109: TRANSMISSION HOUSING or a 4642301205: TRANSMISSION HOUSING, this kit guarantees a factory-spec rebuild.

Symptoms of Failure

• Transmission fluid seepage from bolt holes: Worn or missing loose parts can compromise sealing surfaces, leading to slow oil leaks around the housing joints. This is a common symptom when the 4642.199.776 set is not replaced during service.
• Vibration or rattling at low RPM: Degraded fasteners within the loose parts kit can cause internal components to shift, producing audible noise and driveline shudder during gear engagement.
• Intermittent gear slippage under load: If retaining elements fail, the shift system may lose alignment, causing erratic power delivery. This often occurs alongside a worn 0730365125: TYPE PLATE.
• Difficulty mounting auxiliary components: Missing or stripped hardware from the loose parts set prevents secure installation of covers and screens, leading to contamination ingress.

Technical Specifications

Compatibility

This loose parts kit is primarily designed for the ZF WG 150 transmission series. Based on the part type and housing interface, it is also compatible with the WG 180 and WG 200 models when used with the appropriate housing variant. The 4642.199.776 set integrates directly with the 0631311009: GROOVED STUD for precise alignment. It is not recommended for older WG 120 or WG 130 series without cross-referencing the housing bore pattern.
