ZF 4657.183.245 LOOSE PARTS for WG190 | OEM Genuine Part

Overview

The ZF 4657.183.245 LOOSE PARTS for WG190 is a critical service kit designed to restore the precise fit and function of internal components within the WG 190 series transmission. This OEM genuine part set includes the necessary hardware, seals, and small fittings that secure and align major assemblies within the gearbox. As a loose parts kit, it addresses the micro-tolerances required for smooth power flow and hydraulic pressure regulation. The SKU 4657.183.245 is specifically engineered to interface with the main casing and structural elements, such as the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring that every fastener and alignment component meets factory specifications for durability.

Symptoms of Failure

When the ZF 4657.183.245 loose parts degrade or are missing during a rebuild, operators typically encounter distinct operational issues. Oil seepage at housing joints is a primary indicator, as worn gaskets or loose hardware in this kit compromise the seal between the HOUSING REAR PART and the main case. Intermittent gear slipping under load occurs when retaining hardware loosens, allowing shafts to shift out of alignment. Unusual metallic rattling from the bell housing signals that loose fasteners are vibrating against internal walls. Finally, erratic shift timing can result from degraded locating pins that misalign valve body components, a common long-tail search query for WG190 transmission failures.

Technical Specifications

Compatibility

This loose parts kit is primarily designed for the ZF WG 190 series, but its application extends to closely related models within the same modular family. It is compatible with the WG180 and WG200 transmissions, where the mounting interfaces and fastener patterns are shared. The kit also supports the WG150 and WG210 variants when used in conjunction with the HOUSING REAR SECTION adapter. Always verify the specific revision of your transmission housing, as the 4657.183.245 kit includes the FIXING PLATE and SCREEN SHEET (4657301032) which vary between early and late production units.

Frequently Asked Questions

Q: Can the 4657.183.245 kit be reused after disassembly?
A: No. ZF specifies that all loose parts in this kit, including seals and locking plates, are single-use items. Reusing them risks oil leaks and fastener loosening under vibration.

Q: Does this kit include the screen sheets for the oil pan?
A: Yes. The 4657.183.245 kit contains both the SCREEN SHEET (4657301032) and the finer SCREEN SHEET (4657301033) for the WG190 sump.

Q: How do I verify if this kit fits my WG190 serial number?
A: Check the transmission data plate for the “Housing Part No.” If it begins with 4657, this kit is compatible. For housings using the HOUSING REAR SECTION (4657298101), additional cap screws from the table above may be required.
