ZF 4657.199.015 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.199.015 LOOSE PARTS kit is a critical OEM service component designed specifically for the WG 210 series transmission. This assembly consolidates essential hardware and sealing elements that maintain the structural integrity of the gearbox’s internal architecture. Positioned within the main casing assembly, this kit works in conjunction with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure precise alignment of rotating shafts and prevent contamination ingress. The SKU 4657.199.015 is an original ZF part, guaranteeing exact fitment and metallurgical standards required for heavy-duty industrial applications.

Symptoms of Failure

• Progressive oil seepage at housing joints: When the loose parts in this kit degrade, you may notice fluid weeping from the seam between the HOUSING REAR PART and the main casing, particularly after thermal cycling.
• Intermittent gear engagement hesitation: Worn locating pins or fasteners can cause micro-movement of internal components, leading to delayed clutch pack engagement under load.
• Abnormal vibration during torque conversion: Loose hardware within the assembly allows the CYLINDRICAL PIN to shift, creating resonant vibrations that transmit through the driveline at specific RPM ranges.
• Metallic debris in transmission fluid: Fatigue failure of retaining plates or screws from this kit can shed particles into the oil circuit, accelerating wear on valve bodies.

Technical Specifications

Compatibility

This loose parts kit is engineered for the ZF WG 210 series, but its hardware configuration also supports select models in the WG180, WG200, and WG250 families where identical housing bore patterns exist. The kit integrates directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT found in these transmissions. Always verify your transmission’s serial number against ZF’s cross-reference database, as minor casting revisions in the HOUSING REAR PART may affect fitment. The CYLINDRICAL PIN included in this kit is dimensionally identical to pins used in WG180 and WG200 auxiliary drive housings.
