ZF 0750.147.198 HOSE PIPE for WG150/WG200/WG201 | OEM Genuine Part

Overview

The ZF 0750.147.198 HOSE PIPE is a critical fluid transfer component engineered for the lubrication and cooling circuits within ZF WG150, WG200, and WG201 series transmissions. This OEM genuine part channels pressurized hydraulic oil between the valve body and the upper clutch housing, ensuring consistent flow to bearings and rotating assemblies. The SKU 0750.147.198 is manufactured to exact factory tolerances, preventing pressure drops that can compromise shift quality. When replacing this hose pipe, technicians often inspect the adjacent TRANSMISSION HOUSING (4642101109) for wear, as misalignment can accelerate hose fatigue.

Symptoms of Failure

• External hydraulic oil seepage near the transmission bell housing or mid-plate, often mistaken for a pan gasket leak.
• Delayed or erratic gear engagement under load, caused by insufficient clutch pack pressure due to fluid bypass.
• Audible whining or cavitation noise from the pump, indicating air ingestion through a cracked hose pipe.
• Overheating transmission fluid with visible discoloration, as restricted flow reduces heat exchanger efficiency.

Technical Specifications

Compatibility

This hose pipe is directly compatible with ZF WG150, WG200, and WG201 series transmissions used in off-highway vehicles, agricultural tractors, and material handlers. It also fits select WG180 variants with the same fluid routing architecture. For proper installation, verify that the TRANSMISSION HOUSING (4642301205) is free of burrs at the connection port. Always replace the TYPE PLATE (0730365125) if it becomes illegible during service, and secure the hose with the correct GROOVED STUD (0631311009) to prevent vibration loosening.
