ZF 4657.183.350 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.350 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 fasteners required to secure and align the main structural elements of the gearbox. Positioned within the central casing assembly, this kit interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure precise axial alignment. The SKU 4657.183.350 is factory-matched to the WG210 platform, guaranteeing correct thread pitch and load ratings for long-term durability under high-torque industrial applications.

Symptoms of Failure

• Oil seepage at housing joints: Worn or missing loose parts from this kit cause micro-gaps between the HOUSING REAR PART and the main body, leading to visible fluid weeping during operation.
• Abnormal gear rattle or vibration: When the fasteners in the 4657.183.350 set lose clamping force, the HOUSING REAR SECTION shifts slightly, producing a low-frequency shudder under load.
• Intermittent gear slipping: Loose structural components allow the internal shaft stack to misalign, causing temporary loss of torque transfer in higher gears.
• Increased metallic debris in oil pan: Fretting corrosion from loose mating surfaces generates fine steel particles that contaminate the lubricant.

Technical Specifications

Compatibility

While the 4657.183.350 is factory-specified for the WG 210 transmission, it also serves as a direct replacement in the WG180 and WG200 series when used with the corresponding TRANSMISSION HOUSING. The kit is not backward-compatible with older WG120 or WG150 models due to different bolt patterns. Always verify housing casting numbers before installation.
