Overview
The ZF 4657.199.033 LOOSE PARTS kit is a critical service package designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential loose hardware and fasteners required to secure internal components during a rebuild or major repair. Positioned within the main casing assembly, these parts ensure that the TRANSMISSION HOUSING and its adjoining sections remain rigidly aligned under high torque loads. The SKU 4657.199.033 is factory-matched to the WG210 platform, guaranteeing precise fitment and eliminating the guesswork associated with aftermarket substitutes.
Symptoms of Failure
- Transmission housing oil seepage: When the loose parts in this kit fatigue, the seal between the HOUS.FRONT SECT and the main body degrades, causing fluid to weep from mating surfaces.
- Gear engagement hesitation or slipping: Worn fasteners allow micro-movement of the HOUSING REAR PART, which misaligns shift rails and leads to delayed or incomplete gear changes.
- Abnormal metallic rattling from the bell housing: Loose CYLINDRICAL PIN components within the kit can vibrate against the casing, producing a distinct rattle at idle.
- Increased driveline backlash: Degraded fixing elements allow the internal bearing carriers to shift, creating a noticeable clunk during acceleration or deceleration.

Frequently Asked Questions
Q: Can I use the 4657.199.033 kit on a WG180 transmission?
A: Yes, this loose parts kit is mechanically compatible with the WG180, WG200, and WG250 models, as they share the same housing bolt pattern and dowel pin locations as the WG210.
Q: Does this kit include the cap screws for the rear housing?
A: The kit contains the primary fasteners and pins for the main housing sections. For additional high-tensile cap screws, we recommend ordering 0636100803 separately if your rebuild requires replacements for all bolts.
Q: How do I confirm the correct orientation of the cylindrical pin?
A: The CYLINDRICAL PIN should be inserted flush with the housing face; it aligns the front and rear sections without protruding into the gear cavity.
