ZF 4657.183.307 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.307 LOOSE PARTS for WG210 is a critical service kit designed for the internal valve body and clutch pack assembly of the WG 210 series transmission. This OEM genuine part, identified by SKU 4657.183.307, includes the necessary loose components—such as seals, springs, and retaining rings—that ensure precise hydraulic pressure control and smooth gear engagement. It sits directly within the main control unit of the transmission, acting as a wear-item refresh kit to restore factory tolerances. When replacing this kit, it is common to also inspect the 4657101080: TRANSMISSION HOUSING for cracks or warping, as the housing provides the structural foundation for these loose parts.

Symptoms of Failure

• Delayed or harsh shifting: Worn loose parts cause erratic clutch pack engagement, leading to noticeable lag or jarring shifts during acceleration.
• Internal hydraulic leaks: Degraded seals within the 4657.183.307 kit allow transmission fluid to bypass, resulting in low line pressure and eventual gear slippage.
• Erratic neutral-to-drive engagement: A failing kit often produces a delayed or incomplete engagement when shifting from park to drive, especially under load.
• Contaminated fluid with metallic debris: As these loose parts wear, small metal particles can circulate, accelerating damage to the 4657201167: HOUS.FRONT SECT and adjacent valve body components.

Technical Specifications

Compatibility

This loose parts kit is engineered for the ZF WG210 series, but it also fits select variants of the WG180, WG200, and WG250 models where the internal valve body geometry matches. It is not backward-compatible with older WG120 or WG150 units without modification. For proper installation, always verify the condition of the 4657201171: HOUSING REAR PART and the 4657298103: HOUSING REAR SECTION, as these housings must be free of scoring to ensure a proper seal with the new loose parts.
