Overview
The ZF 4657.183.299 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure and align the main transmission housing sections during rebuild or repair. The SKU 4657.183.299 functions as a consolidation of loose hardware that interfaces directly with the 4657101080: TRANSMISSION HOUSING and the 4657201167: HOUS.FRONT SECT, ensuring proper clamping force and structural integrity under high-torque conditions. Without this kit, the transmission cannot maintain correct gear mesh alignment or oil sealing.
Symptoms of Failure
- Transmission oil weeping from housing joints — Worn or missing loose parts cause the 4657201171: HOUSING REAR PART to shift, leading to gradual fluid loss and eventual low-pressure faults.
- Intermittent gear slippage under load — Loose fasteners allow the 4657298103: HOUSING REAR SECTION to micro-move, disrupting clutch pack engagement and causing erratic shifting.
- Abnormal vibration or driveline noise — Degraded positioning pins and bolts create play between housing halves, producing a distinct metallic rattle during acceleration.
- Hard-to-diagnose hydraulic pressure drops — When the loose parts kit fails, internal oil galleries misalign, reducing pressure to the torque converter and clutches.

Compatibility
This loose parts kit is engineered for the ZF WG 210 series, but it also cross-fits several other ZF off-highway transmissions. Compatible models include the WG 180, WG 200, WG 210, and WG 220 series. The kit is specifically validated for use with the 4657101080: TRANSMISSION HOUSING and the 4657201167: HOUS.FRONT SECT. Always verify your transmission serial number before ordering, as minor variations exist between early and late production runs of the WG 200 series.
