Overview
The ZF 4656.183.355 LOOSE PARTS set is a critical OEM genuine service kit designed specifically for the WG160 series transmission. This assembly contains the essential loose components required to secure and align internal transmission housings during rebuild or repair. Positioned within the main gear case assembly, these parts interface directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain structural integrity under heavy torque loads. The SKU 4656.183.355 is factory-matched to ZF’s original tolerances, ensuring that every fastener, spacer, and alignment component meets the exact specifications for the WG160 platform.
Symptoms of Failure
- Transmission oil seepage at housing joints: When the loose parts in this kit degrade, the seal between the HOUSING REAR PART and the main casing weakens, leading to visible oil weeping around mating surfaces.
- Abnormal gear engagement noise: Worn or missing loose components can cause micro-movement between the HOUSING REAR SECTION and the front section, producing a distinct clattering sound during gear shifts.
- Increased vibration at highway speeds: Deteriorated alignment pins and fixing plates allow the housing sections to shift slightly, transmitting vibration through the drivetrain under load.
- Hard shifting or gear slippage: Loss of precise housing alignment directly affects shift fork positioning, causing delayed or incomplete gear engagement in the WG160.

Compatibility
This genuine ZF 4656.183.355 LOOSE PARTS kit is engineered primarily for the WG160 transmission series. It is also compatible with the following ZF models that share the same housing architecture: WG180, WG200, and WG150. Always verify the housing part numbers before installation, as the kit interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure correct fitment. For rear-section applications, the kit works with both the HOUSING REAR PART and the HOUSING REAR SECTION.

Frequently Asked Questions
Q: Can I use the ZF 4656.183.355 kit on a WG200 transmission?
A: Yes, the kit is compatible with WG200 models that share the same housing interface as the WG160. However, you must verify that the TRANSMISSION HOUSING and HOUS.FRONT SECT match the original part numbers.
Q: What is the typical lifespan of these loose parts before replacement is needed?
A: Under normal operating conditions, the components in this kit last the life of the transmission. Replacement is only necessary if you observe oil leaks, vibration, or if the housing sections are separated during a rebuild.
Q: Does this kit include the cap screws and screen sheets listed in the related components table?
A: No, the 4656.183.355 kit contains only the specific loose parts for the WG160. The cap screws (0636100817, 0636100803) and screen sheets (4656301016, 4656301017) are sold separately as individual OEM parts.
