Overview
The ZF 4657.183.413 LOOSE PARTS kit is a critical service component designed specifically for the WG 211 Series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure and align the main transmission housing sections during rebuild or repair. The SKU 4657.183.413 sits at the interface between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring precise clamping force and preventing oil migration between chambers. Without this loose parts set, the structural integrity of the gear train assembly is compromised, leading to misalignment and premature wear.
Symptoms of Failure
- External oil seepage at housing joints: When the 4657.183.413 fasteners lose torque or the sealing elements degrade, transmission fluid escapes between the HOUSING REAR PART and the main casing, creating visible drips under the vehicle.
- Intermittent gear engagement hesitation: Worn or missing CYLINDRICAL PIN components within the loose parts kit allow the housing sections to shift microscopically, causing delayed clutch pack engagement.
- Abnormal vibration during load shifts: Loose housing bolts from a degraded 4657.183.413 set permit flexing of the transmission case, transmitting harsh vibrations through the driveline under torque.
- Contaminated hydraulic fluid: Failure of the sealing elements in this loose parts kit allows debris ingress at the housing split line, leading to valve body clogging and erratic shift patterns.

Frequently Asked Questions
Q: Can I reuse the existing bolts from my old loose parts kit?
No. The 4657.183.413 kit contains torque-to-yield fasteners that must be replaced with new OEM parts to maintain proper clamping force. Reusing bolts risks housing separation under load.
Q: Does this kit include the cylindrical pin for alignment?
Yes. The 4657.183.413 set includes the CYLINDRICAL PIN (0631306816) required for precise alignment between the front and rear housing sections.
Q: Is this part compatible with the WG180 transmission?
Yes, the 4657.183.413 loose parts kit is fully compatible with WG180, WG200, WG210, and WG211 models, as they share identical housing bolt patterns and seal configurations.
