Overview
The ZF 4657.183.098 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 small components required to secure and align internal assemblies during a rebuild or major repair. Positioned within the main casing, these parts ensure that the TRANSMISSION HOUSING and its adjacent sections remain properly torqued and vibration-resistant under heavy load. The SKU 4657.183.098 is often ordered alongside a full gasket set to guarantee a leak-free seal between the HOUS.FRONT SECT and the HOUSING REAR PART.
Symptoms of Failure
When the components within the 4657.183.098 LOOSE PARTS kit degrade or become damaged, operators typically notice three distinct failure modes. First, persistent oil seepage from the transmission bell housing often occurs when the included fasteners lose their clamping force. Second, intermittent gear slipping under moderate acceleration can result from a loose CYLINDRICAL PIN that allows the shift fork to drift out of alignment. Third, abnormal metallic rattling during idle indicates that internal retaining plates have loosened, allowing the FIXING PLATE to vibrate against the casing. Finally, hard shifting between forward gears may point to a missing or deformed SCREEN SHEET that has allowed debris to clog the valve body passages.

Frequently Asked Questions
Q: Can I reuse the old bolts from my WG210 instead of buying the 4657.183.098 kit?
A: ZF strongly discourages reusing torque-to-yield fasteners. The 4657.183.098 LOOSE PARTS kit includes fresh cap screws and pins that meet OEM specifications, preventing stress fractures and ensuring proper clamp load on the TRANSMISSION HOUSING.
Q: Does this kit include the screen sheets for the oil filter?
A: No. The 4657.183.098 kit focuses on loose hardware (bolts, pins, clips). For replacement filter elements, order 4657301032 or 4657301033 separately.
Q: How do I confirm this kit fits my ZF transmission?
A: Verify your transmission model number (e.g., WG210) and check the casting numbers on the HOUS.FRONT SECT and HOUSING REAR PART. If both match the WG series, this kit is the correct hardware set.
