Overview
The ZF 0750.147.276 HOSE PIPE is a critical fluid conduit engineered specifically for the WG 211 transmission series. This OEM genuine part directs pressurized hydraulic oil between the valve body and the clutch drum assembly, ensuring precise actuation and lubrication within the gear train. As an original equipment component, SKU 0750.147.276 guarantees exact fitment and material integrity to withstand continuous thermal cycling and high-pressure surges. When installed alongside a properly functioning 4657120005: PRESSURE REGULATOR, this hose pipe maintains stable line pressure essential for shift quality and torque converter lockup.
Symptoms of Failure
- External hydraulic oil seepage around the WG211 bellhousing or mid-plate area, often presenting as a slow drip after extended operation.
- Delayed or harsh engagement when shifting from Neutral to Drive or Reverse, caused by insufficient fluid volume reaching the clutch piston due to a cracked or collapsed hose pipe.
- Intermittent gear slippage under moderate to heavy load, particularly in 3rd and 4th gears, as the compromised hose cannot sustain the required hydraulic pressure.
- Contaminated transmission fluid showing fine rubber particles, indicating internal degradation of the hose lining that can obstruct the 0501211384: VALVE.

Compatibility
This hose pipe is primarily designed for the ZF WG 211 series, but it also fits select variants of the WG180 and WG200 families due to shared hydraulic circuit architecture. It is commonly used in WG211-2, WG211-3, and WG211-4 models found in medium-duty trucks and construction equipment. For proper sealing, always pair this hose with a new 0630532183: INDENTED RING and verify the condition of the 4656306145: PISTON to prevent cross-leakage. The part is not interchangeable with the WG150 series without adapter fittings.
