Overview
The ZF 0750.147.268 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 210 Series transmission. This OEM genuine part channels pressurized hydraulic oil between the valve body and the clutch pack assembly, ensuring precise actuation and lubrication within the gear train. As a direct replacement for the original equipment, the SKU 0750.147.268 guarantees factory-specified flow rates and pressure integrity. When installed alongside the 4657101042: TRANSMISSION HOUSING, this hose pipe maintains the sealed circuit necessary for consistent shift quality under heavy-duty cycles.
Symptoms of Failure
- External hydraulic oil leaks near the transmission bell housing – Cracks or abrasions in the hose pipe wall cause fluid seepage, often visible as drips on the chassis or ground beneath the vehicle.
- Delayed or harsh gear engagement – A compromised hose pipe reduces line pressure, leading to sluggish shifts or sudden clunks when moving from neutral to drive.
- Overheating transmission fluid – Restricted flow through a collapsed or kinked hose pipe prevents adequate cooling, causing the transmission to run hotter than normal.
- Intermittent loss of forward or reverse gears – Air ingestion through a damaged hose pipe creates aerated fluid, resulting in unpredictable gear slip or temporary loss of drive.

Compatibility
This hose pipe is primarily designed for the ZF WG 210 Series, but it also fits several related heavy-duty transmission models that share the same hydraulic circuit architecture. Compatible transmissions include the WG 180, WG 200, WG 210, and WG 250 series used in off-highway trucks, loaders, and agricultural machinery. For proper sealing, always pair this part with the 4657201028: HOUS.FRONT SECT and the 4657201013: HOUSING REAR PART. Secure the assembly using the 0631306792: CYLINDRICAL PIN to prevent misalignment during installation.
