ZF 4657.183.387 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.387 LOOSE PARTS kit is a critical service component engineered specifically for the WG 210 series transmission. This genuine OEM assembly contains the necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies during a rebuild or major repair. The SKU 4657.183.387 directly interfaces with the main casing structure, ensuring that the TRANSMISSION HOUSING maintains proper alignment with the HOUS.FRONT SECT and the HOUSING REAR PART. Without this specific loose parts set, the transmission’s structural integrity is compromised, leading to premature wear on the gear train.

Symptoms of Failure

When the ZF 4657.183.387 LOOSE PARTS begin to degrade or are missing during reassembly, operators will notice distinct operational issues. Common failure indicators include:

• Intermittent oil seepage at casing joints – Worn or missing fasteners from this kit cause the HOUSING REAR SECTION to shift, breaking the seal integrity.
• Audible clunking during gear engagement – Loose internal components allow axial play, resulting in harsh shifts and metallic noise.
• Progressive gear slippage under load – Without the correct tension from the loose parts, clutch packs lose clamping force, causing power loss.
• Vibration at highway speeds – Misalignment of the housing sections due to degraded hardware leads to driveline shudder.

Technical Specifications

Compatibility

This genuine ZF 4657.183.387 LOOSE PARTS kit is primarily designed for the WG 210 transmission series. Based on the structural design of the housing interfaces, it is also compatible with the WG 180 and WG 200 series when used in conjunction with the correct FIXING PLATE. For installations requiring additional filtration, the SCREEN SHEET (4657301032) and the SCREEN SHEET (4657301033) are recommended. Always verify the housing variant before ordering; the CAP SCREW (0636100803) may be required for deeper bolt holes.
