ZF 4657.183.090 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.090 LOOSE PARTS kit is a critical service package designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential loose components required to restore the internal valve body and clutch pack alignment within the gearbox. Positioned inside the main transmission casing, this kit directly interfaces with the TRANSMISSION HOUSING to ensure precise hydraulic flow and mechanical engagement. The SKU 4657.183.090 is factory-sealed and includes all necessary fasteners and spacers for a complete overhaul of the WG210 shift mechanism.

Symptoms of Failure

• Delayed or harsh gear engagement: When the loose parts wear, you may notice a pronounced lag when shifting from Neutral to Drive or Reverse, often accompanied by a jarring thud.
• Intermittent loss of hydraulic pressure: Worn components inside this kit can cause erratic oil flow, leading to slipping under load or during uphill climbs.
• Visible oil seepage around the valve body: Degraded seals and gaskets within the 4657.183.090 assembly allow transmission fluid to weep past the HOUS.FRONT SECT interface, leaving wet spots on the bell housing.
• Unusual whining or grinding noises: Loose or fatigued pins and plates create metal-on-metal contact, particularly during cold starts or low-speed maneuvers.

Technical Specifications

Compatibility

This genuine ZF 4657.183.090 LOOSE PARTS kit is engineered for the WG 210 series transmission family. It is also fully compatible with the WG180, WG200, and WG250 models when used in conjunction with the correct HOUSING REAR PART. The kit integrates directly with the CYLINDRICAL PIN alignment system to ensure proper indexing of the shift forks. For heavy-duty applications in WG180 and WG200 units, verify that the front housing section matches the 4657.183.090 configuration before installation.
