ZF 4657.183.370 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.370 LOOSE PARTS for WG210 is a critical internal service kit designed to restore the precise hydraulic and mechanical clearances within the WG 210 series transmission. This genuine OEM part, identified by SKU 4657.183.370, contains the specific loose components—including seals, thrust washers, and retaining elements—that sit between the main housing sections. It directly interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure proper alignment and oil flow control. Without this kit, the internal assembly cannot maintain the necessary pressure for clutch engagement.

Symptoms of Failure

• Intermittent gear slippage under load: When the loose parts wear, hydraulic pressure bleeds past worn seals, causing the transmission to slip during uphill climbs or heavy hauling.
• External oil seepage at housing joints: Degraded gaskets and O-rings within the 4657.183.370 kit lead to visible fluid leaks around the mating surfaces of the HOUSING REAR PART.
• Delayed engagement from Neutral to Drive: Worn thrust washers allow axial play, which delays clutch pack compression, resulting in a noticeable lag when shifting.
• Metallic debris in the oil pan: As the loose parts fragment, small particles circulate, often first detected during routine oil changes.

Technical Specifications

Compatibility

This genuine ZF loose parts kit is engineered specifically for the WG 210 transmission series. It is also compatible with the WG 180 and WG 200 models where the same housing architecture is used. The kit replaces the internal wear items that sit between the HOUSING REAR SECTION and the main gearset. Always verify your transmission serial number against ZF’s application guide to confirm fitment.
