ZF 0750.147.238 HOSE PIPE | OEM Genuine Part

Overview

The ZF 0750.147.238 HOSE PIPE is a critical fluid transfer component engineered for high-pressure hydraulic circuits within ZF construction machinery transmissions. This OEM genuine part channels transmission oil between the valve body and cooler lines, ensuring consistent lubrication and thermal regulation. Positioned directly within the main pressure gallery, the SKU 0750.147.238 maintains system integrity by withstanding extreme thermal cycling and vibration. When paired with the 4143101009 HOUSING and 4143301025 HOUSING, this hose pipe forms a sealed conduit that prevents pressure loss during heavy-load operations.

Symptoms of Failure

• External oil seepage at hose crimp points – Visible fluid accumulation near the transmission housing indicates degraded hose material or loose fittings, often accompanied by a burnt oil smell.
• Erratic gear engagement under load – A worn 0750.147.238 can cause pressure drops, leading to delayed or harsh shifting when the machine is under heavy excavation or lifting stress.
• Overheating transmission fluid – Restricted flow through a collapsed or kinked hose pipe reduces cooling capacity, triggering thermal alarms or elevated temperature gauge readings.
• Whining or cavitation noise from pump – Air ingestion through a cracked hose creates a high-pitched whine, particularly during cold starts or rapid acceleration cycles.

Technical Specifications

Compatibility

This hose pipe is designed for ZF powershift transmissions commonly used in wheel loaders, excavators, and dozers. It is a direct fit for the WG180 and WG200 series, as well as the WG150 and WG210 models. Always verify the routing path against your transmission’s hydraulic schematic. For complete sealing integrity, replace the 0634313603 O-RING and 4475280018 SCREW PLUG simultaneously to prevent secondary leaks.
