ZF 4657.183.385 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.385 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 Series transmission. This genuine OEM assembly contains the necessary loose hardware and small components required to secure and seal the main structural elements of the gearbox. Positioned within the transmission’s central casing assembly, this kit interfaces directly with the 4657101082: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT, ensuring proper alignment and torque retention during rebuilds or maintenance. The SKU 4657.183.385 is your guarantee of a factory-spec fit for the WG210 platform.

Symptoms of Failure

When the loose parts in this kit degrade or are lost during service, operators often report specific drivability issues. Look for these failure symptoms to identify a need for replacement:

• Transmission oil seepage at casing joints: Worn or missing fasteners from this kit cause the 4657201170: HOUSING REAR PART to lose clamping force, leading to fluid leaks.
• Abnormal gear engagement noise: Loose hardware allows micro-movement between the 4657298102: HOUSING REAR SECTION and the main body, creating audible clunks during shifts.
• Intermittent gear slipping under load: If the fixing hardware is compromised, the internal alignment shifts, causing the clutch packs to lose pressure momentarily.
• Vibration at highway speeds: Unsecured housing sections can resonate, transmitting vibration through the driveline.
