Overview
The ZF 4656.183.364 LOOSE PARTS kit is a critical service component engineered specifically for the WG 160 transmission series. This genuine OEM assembly contains the necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies within the gearbox. As a loose parts set, it ensures that the TRANSMISSION HOUSING and its adjoining sections remain properly torqued and aligned during high-torque operations. The SKU 4656.183.364 is frequently ordered during major overhauls to replace worn or corroded hardware that can compromise drivetrain integrity.
Symptoms of Failure
- Transmission fluid seepage at housing joints: When the loose parts kit components degrade, you may notice oil weeping between the HOUS.FRONT SECT and the main case, indicating fastener fatigue or seal failure.
- Abnormal gear rattle or vibration under load: Worn positioning pins or loose cap screws from this kit can allow the HOUSING REAR PART to shift slightly, creating audible noise and driveline shudder.
- Intermittent gear engagement difficulty: A failing loose parts set may cause misalignment of the HOUSING REAR SECTION, leading to delayed or harsh shifting in the WG160.
- Increased metallic debris in oil pan: Broken fasteners or sheared pins from this kit can shed particles into the lubrication system, accelerating wear on bearings and gears.

Compatibility
This loose parts kit is primarily designed for the ZF WG 160 series transmissions. Based on its fastener dimensions and screen sheet geometry, it is also compatible with the WG 180 and WG 200 series when used in conjunction with the correct housing variants. The kit is not recommended for older WG 120 models without verifying the FIXING PLATE alignment holes. Always cross-reference your transmission serial number with the OEM parts catalog before installation.

Frequently Asked Questions
Q: Can I reuse the old fasteners from my WG160 instead of buying the 4656.183.364 kit?
A: ZF recommends against reusing cap screws and pins from this loose parts set because torque-to-yield fasteners lose clamping force after removal. Using a new kit ensures proper preload and prevents oil leaks at the housing joints.
Q: Does this kit include the screen sheets or only the hardware?
A: The 4656.183.364 LOOSE PARTS set includes both the mounting hardware (cap screws, cylindrical pins, fixing plates) and the screen sheets (part numbers 4656301016 and 4656301017) for complete oil filtration restoration.
Q: How do I verify if my transmission uses the WG160 housing variant?
A: Check the casting number on the main transmission housing near the bellhousing flange. If it matches the 4656101055 profile, this kit is compatible. For WG180 or WG200 models, confirm the rear section part number matches 4656298047.
