ZF 4657.183.356 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.356 LOOSE PARTS kit is a critical service assembly designed for the WG 210 series transmission. This genuine OEM part set contains the specific fasteners, seals, and positioning components required to secure the main housing sections during rebuild or repair. The SKU 4657.183.356 is installed directly between the HOUS.FRONT SECT and the HOUSING REAR PART, ensuring proper alignment and clamping force. Without this loose parts kit, the transmission housing cannot maintain structural integrity under load, making it a mandatory replacement item whenever the main casing is disassembled.

Symptoms of Failure

• Transmission fluid seepage at housing seams: When the 4657.183.356 loose parts degrade, the seal between the TRANSMISSION HOUSING and rear sections fails, causing oil to weep from mating surfaces.
• Audible clunking during gear engagement: Worn fasteners in this kit allow micro-movement between the HOUSING REAR SECTION and front casing, producing metallic noise under torque.
• Intermittent gear slippage in WG210 units: Loss of clamping pressure from degraded loose parts causes misalignment of internal shafts, leading to erratic power delivery.
• Vibration at highway speeds: A compromised 4657.183.356 assembly permits harmonic resonance between housing sections, felt as driveline shudder.

Technical Specifications

Compatibility

This genuine ZF loose parts kit is engineered for the WG 210 transmission family. It is also compatible with WG180 and WG200 models that share the same housing architecture. The 4657.183.356 interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT. For WG190 and WG220 variants, verify housing bolt patterns before installation. This kit is not suitable for older ZF 4HP or 5HP series transmissions.
