Overview
The ZF 4657.199.082 LOOSE PARTS kit is a critical service assembly designed exclusively for the WG 210 series transmission. This genuine OEM part contains the essential fasteners, seals, and positioning components required to secure the main housing sections during a rebuild or overhaul. The SKU 4657.199.082 directly interfaces with the transmission’s structural core, ensuring that the TRANSMISSION HOUSING maintains proper alignment under high torque loads. Without this specific loose parts set, the internal gear train cannot be safely contained, leading to catastrophic misalignment.
Symptoms of Failure
- External oil seepage at housing seams: When the 4657.199.082 components degrade, the clamping force between the HOUS.FRONT SECT and the main body weakens, causing ATF to weep from the mating surfaces.
- Persistent gear slippage under load: Worn fasteners in this kit allow micro-movement between the HOUSING REAR PART and the valve body, resulting in inconsistent clutch pack engagement.
- Abnormal driveline vibration: A loose rear section creates axial play, which manifests as a low-frequency shudder during 3rd-to-4th gear shifts.
- Difficulty in gear engagement: If the HOUSING REAR SECTION shifts out of tolerance, the shift fork alignment is compromised, causing hard or delayed shifts.

Compatibility
This genuine loose parts kit is engineered specifically for the ZF WG 210 series, but its fastening geometry also supports the WG 180 and WG 200 transmission models when used with the correct housing variants. It is a direct replacement for the original hardware in WG210, WG200, and WG180 gearboxes manufactured after 2010. Always verify that your TRANSMISSION HOUSING casting number matches the kit’s bolt pattern before installation.

Frequently Asked Questions
Q: Can I reuse the original bolts from my old housing instead of buying the 4657.199.082 kit?
A: No. ZF specifies that all fasteners in this loose parts kit are single-use torque-to-yield bolts. Reusing them risks bolt fatigue and sudden housing separation under load.
Q: Does this kit include the gaskets for the HOUS.FRONT SECT and HOUSING REAR PART?
A: This specific SKU contains only the loose hardware (bolts, pins, and plates). Separate gasket sets must be ordered for sealing the HOUS.FRONT SECT and HOUSING REAR PART interfaces.
Q: How do I confirm that the 4657.199.082 fits my WG210 transmission?
A: Check the casting number on your TRANSMISSION HOUSING. If it ends with “-210” or “-200”, this kit is compatible. For WG180 units, verify the bolt hole count matches 12 positions.
