ZF 4657.183.241 LOOSE PARTS for WG190 | OEM Genuine Part

Overview

The ZF 4657.183.241 LOOSE PARTS for WG190 is a critical service kit designed to restore the internal sealing and alignment integrity of your ZF WG190 series transmission. This OEM genuine part, identified by SKU 4657.183.241, contains the specific loose hardware and small components that secure the main housing sections together. It sits at the junction between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring that the entire assembly remains rigid under high torque loads. Without this kit, the structural integrity of the gearbox is compromised, leading to misalignment of internal shafts and bearings.

Symptoms of Failure

• Oil weeping from housing seams: When the loose parts in this kit degrade, the seal between the HOUSING REAR PART and the main case fails, causing visible oil leaks at the joint lines.
• Intermittent gear slipping under load: Worn fasteners allow the HOUSING REAR SECTION to shift slightly, altering gear mesh depth and causing the transmission to slip during acceleration.
• Abnormal vibration at highway speeds: Loss of clamping force from deteriorated components leads to micro-movement between housing sections, generating a low-frequency vibration that worsens with RPM.
• Difficulty engaging reverse gear: Misalignment caused by failing loose parts can bind the shift rail, making reverse engagement hard or noisy.

Technical Specifications

Compatibility

This genuine ZF 4657.183.241 LOOSE PARTS kit is engineered specifically for the WG190 transmission series. It is also compatible with the closely related WG180 and WG200 models that share the same housing bolt pattern and sealing interface. The kit works in conjunction with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to create a leak-free, vibration-resistant assembly. For full rebuilds, pair this kit with the HOUSING REAR PART and the HOUSING REAR SECTION to ensure all mating surfaces are properly secured.
