ZF 4657.183.005 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.005 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 Series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies during a rebuild or overhaul. The SKU 4657.183.005 is typically installed within the main gear case to retain the clutch drum and planetary gear sets, ensuring precise axial alignment under high torque loads. When paired with a new TRANSMISSION HOUSING, this loose parts set guarantees that all mating surfaces remain properly clamped, preventing micro-movement that can lead to premature wear.

Symptoms of Failure

• Intermittent gear slipping under load: Worn or missing loose parts can allow the clutch pack to shift out of alignment, causing the transmission to momentarily lose drive power when climbing or hauling.
• Metallic rattling from the bell housing: If the retaining hardware becomes loose, planetary gears may develop excessive backlash, producing a distinct knocking sound during deceleration.
• Oil seepage at the housing joint: Degraded sealing elements within the 4657.183.005 kit can cause transmission fluid to weep from the seam between the HOUS.FRONT SECT and the main case.
• Hard shifting or delayed engagement: Misaligned loose parts may prevent the valve body from receiving consistent hydraulic pressure, leading to harsh or delayed gear changes.

Technical Specifications

Compatibility

This loose parts kit is engineered for the ZF WG 210 Series, but its mounting geometry also suits earlier WG 180 and WG 200 variants that share the same housing bolt pattern. The kit is fully compatible with the HOUSING REAR PART and the CYLINDRICAL PIN used for dowel alignment. It is not recommended for WG 120 or WG 150 models due to differing case depths. Always verify the presence of the original retaining plate before installation.
