ZF 4657.183.059 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

This OEM genuine ZF 4657.183.059 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. It contains the necessary hardware and small components required to secure and align internal assemblies during a rebuild or major repair. The SKU 4657.183.059 sits within the main casing assembly, ensuring that the TRANSMISSION HOUSING and the HOUS.FRONT SECT remain properly fastened under high torque loads. Without this genuine loose parts set, the structural integrity of the gearbox is compromised, leading to premature wear of the HOUSING REAR PART and potential misalignment of the CYLINDRICAL PIN.

Symptoms of Failure

When the ZF 4657.183.059 LOOSE PARTS begin to fatigue or are missing during reassembly, operators will notice distinct operational issues. The most common symptom is a persistent oil leak around the main housing seam, often mistaken for a gasket failure. A second clear indicator is a low-frequency vibration or rumbling during gear engagement, which stems from insufficient clamping force between the HOUS.FRONT SECT and the main body. Third, you may experience intermittent gear slipping under load, particularly in higher ranges, as the CYLINDRICAL PIN loses its precise alignment. Finally, a telltale sign is metallic debris in the oil pan, indicating that the HOUSING REAR PART is shifting against the TRANSMISSION HOUSING.

Technical Specifications

Compatibility

This OEM genuine part is engineered for the ZF WG 210 series, but it also shares mounting patterns with the WG 180 and WG 200 series transmissions. It is a direct fit for any WG210 variant, including the WG210-1, WG210-2, and WG210-3 models. The 4657.183.059 LOOSE PARTS kit is also compatible with certain WG 160 rebuilds where the TRANSMISSION HOUSING dimensions match. Always verify your housing casting number before ordering, as the HOUSING REAR PART may vary slightly in bolt pattern on older units.

Frequently Asked Questions

Q: Can I reuse the old 4657.183.059 LOOSE PARTS during a rebuild?
A: No. ZF engineering recommends replacing all loose parts in this kit during any major overhaul. The fasteners and pins are torque-to-yield components, and reusing them can lead to the failure symptoms described above, including oil leaks and gear slipping.

Q: Does this kit include the CAP SCREWS for the housing?
A: Yes, the 4657.183.059 LOOSE PARTS kit includes the primary fasteners, but it does not include the specific CAP SCREW (0636100801) or CAP SCREW (0636100803) for the rear section. Those must be ordered separately if your transmission requires them.

Q: How do I verify this part fits my WG210 transmission?
A: Check the casting number on your TRANSMISSION HOUSING. If it matches the WG210 series, this kit is a direct fit. For WG180 or WG200 models, measure the bolt hole spacing on the HOUSING REAR PART to confirm compatibility.
