Overview
The ZF 4657.199.016 LOOSE PARTS for WG210 is a critical OEM genuine component designed to maintain the precise internal clearances and operational integrity of your ZF WG210 series transmission. This assembly kit includes essential fasteners, seals, and positioning elements that secure the transmission housing and internal gear sets. The SKU 4657.199.016 specifically addresses the loose hardware set required during rebuilds or major repairs, ensuring that every bolt, pin, and plate meets factory specifications. Without this kit, the structural alignment of the TRANSMISSION HOUSING and the HOUS.FRONT SECT cannot be guaranteed, leading to premature wear.
Symptoms of Failure
When the ZF 4657.199.016 LOOSE PARTS kit begins to fail or is missing components, operators will notice distinct operational issues. Oil leaks around the transmission housing joint are the most common symptom, often caused by degraded seals or loose cap screws. Gear slipping under load occurs when the HOUSING REAR PART shifts out of alignment due to missing cylindrical pins. Abnormal vibration or clunking during gear changes indicates that the fixing plates have loosened, allowing axial play. Finally, difficulty engaging reverse or low gears points to a compromised screen sheet or oil feed housing that has shifted position.

Compatibility
This ZF 4657.199.016 LOOSE PARTS kit is engineered specifically for the WG210 series, but it also shares cross-compatibility with the WG180, WG200, and WG250 models due to identical housing bolt patterns. It is a direct replacement for the loose hardware found in the CYLINDRICAL PIN retention system and the front/rear housing assemblies. Always verify your transmission serial number before ordering, as variations exist in older WG200 units.

Frequently Asked Questions
Q: Can I use the ZF 4657.199.016 kit on a WG200 transmission?
A: Yes, the kit is compatible with WG200 and WG180 models, but you must verify that the cylindrical pin (0631306792) matches your housing bore diameter. Some early WG200 units use a different pin length.
Q: What is the typical lifespan of these loose parts?
A: Under normal operating conditions, the cap screws and fixing plates last the life of the transmission. However, if you experience oil leaks or vibration, inspect the screen sheets (4657301032 and 4657301033) for clogging, which can accelerate wear on the oil feed housing.
Q: Does this kit include the oil feed housing?
A: No, the 4657.199.016 kit does not include the OIL FEED.HOUSG. (part 0750301003). That component is sold separately and is recommended for replacement during any major housing overhaul.
