ZF 4657.183.221 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.221 LOOSE PARTS set is a critical OEM genuine service kit designed specifically for the WG 210 series transmission. This assembly contains the necessary loose hardware and small components required to secure and align internal transmission assemblies during a rebuild or major repair. Positioned within the main gearcase, these parts interface directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure proper torque retention and vibration resistance. The SKU 4657.183.221 is frequently ordered as a mandatory replacement when disassembling the WG210 for clutch pack or bearing service.

Symptoms of Failure

• Transmission oil seepage at housing joints: When the loose parts in this kit wear or corrode, the seal between the HOUSING REAR PART and the main case degrades, leading to slow oil weeping.
• Abnormal gear rattle or loose shift feel: Worn fasteners or locating pins cause micro-movement in the HOUSING REAR SECTION, resulting in audible driveline noise during deceleration.
• Increased drivetrain backlash: If the fixing hardware fails, the housing alignment shifts, creating a noticeable delay between throttle input and gear engagement.
• Recurring bolt loosening after service: Reusing old loose parts often leads to fasteners backing out, requiring a complete re-torque of the housing assembly.

Technical Specifications

Compatibility

This loose parts kit is engineered for the ZF WG 210 series, but it also cross-fits the WG180 and WG200 transmission families due to shared housing bolt patterns. It is compatible with all WG210 variants including the WG210-1, WG210-2, and WG210-3. The kit replaces all original fasteners and alignment components between the TRANSMISSION HOUSING and the rear cover sections. Always verify your transmission serial number against the ZF parts catalog before ordering.
