Overview
The ZF 4657.199.006 LOOSE PARTS kit is a critical service assembly designed for the WG 210 series transmission. This genuine OEM part number 4657.199.006 contains the specific loose components required to secure and align internal sub-assemblies within the transmission housing. It functions as a retention and positioning set, ensuring that the TRANSMISSION HOUSING maintains proper structural integrity during high-torque operations. Without this kit, the HOUS.FRONT SECT and HOUSING REAR PART cannot be correctly fastened, leading to potential misalignment of the gear train.
Symptoms of Failure
When the components within the 4657.199.006 LOOSE PARTS kit degrade, operators often notice distinct failure modes. A primary symptom is intermittent gear slipping under load, which occurs when the retaining hardware loses clamping force. Another common issue is transmission housing oil seepage at the joint seams, indicating that the loose parts are no longer providing a uniform seal. Technicians also report abnormal vibration during gear shifts, which stems from the CYLINDRICAL PIN becoming loose and allowing lateral movement. Finally, difficulty engaging forward or reverse gears is a telltale sign that the positioning elements in this kit have fatigued.

Frequently Asked Questions
Q: Can I reuse the old CYLINDRICAL PIN from my previous service?
A: No. The 4657.199.006 LOOSE PARTS kit includes a new CYLINDRICAL PIN because the original pin often suffers from surface wear that compromises alignment precision.
Q: Does this kit include the CAP SCREWS for the housing?
A: This specific kit focuses on loose positioning parts. For the matching fasteners, you should order 0636100801 or 0636100803 separately to ensure proper torque specifications.
Q: How do I know if my WG 210 needs this kit?
A: If you are replacing the HOUS.FRONT SECT or HOUSING REAR PART, you must install a fresh 4657.199.006 kit to maintain factory tolerances.
