ZF 0750.147.278 HOSE PIPE for WG211 | OEM Genuine Part

Overview

The ZF 0750.147.278 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 211 Series transmission. This OEM genuine part channels pressurized hydraulic oil between the valve body and the clutch housing, ensuring precise lubrication and cooling within the transmission’s internal circuits. The SKU 0750.147.278 is designed to withstand high thermal loads and constant vibration, maintaining a leak-free seal under extreme operating conditions. Without this hose pipe, the transmission cannot maintain the necessary hydraulic pressure for gear engagement, making it an essential element for drivetrain reliability in heavy-duty industrial applications.

Symptoms of Failure

• Hydraulic fluid seepage near the transmission housing: When the hose pipe degrades, you may notice oil residue forming around the WG 211 casing, often mistaken for a gasket failure. This is a common long-tail search query for “ZF transmission oil leak from hose pipe.”
• Erratic gear engagement or delayed shifting: A compromised hose pipe reduces fluid flow to the clutch packs, causing hesitation or harsh shifts during acceleration. Technicians frequently search for “WG211 slipping gears after hose replacement.”
• Overheating transmission fluid: Restricted oil circulation from a collapsed or cracked hose pipe leads to elevated sump temperatures, triggering warning lights. This symptom aligns with “ZF transmission overheating causes.”
• Whining noise from the transmission pump: Air ingestion through a damaged hose pipe creates cavitation, producing a high-pitched whine that intensifies under load.

Technical Specifications

Compatibility

This hose pipe is primarily designed for the ZF WG 211 Series transmission, but it also fits select models within the WG180, WG200, and WG250 families that share the same hydraulic circuit architecture. It is commonly used in off-highway vehicles, construction equipment, and agricultural machinery where ZF powershift transmissions are deployed. Always verify your transmission’s serial number against the OEM parts catalog before installation.
