ZF 0750.147.040 HOSE PIPE for WG180 | OEM Genuine Part

Overview

The ZF 0750.147.040 HOSE PIPE is a critical fluid transfer component engineered specifically for the WG 180 transmission series. This OEM genuine part channels pressurized hydraulic oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation within the gearbox. As an original ZF component, the SKU 0750.147.040 guarantees precise internal diameter and burst pressure ratings that aftermarket alternatives often fail to match. This hose pipe connects directly to the 4644105475: DISCONNECTION assembly, forming a sealed pathway that prevents contamination ingress during high-torque operations.

Symptoms of Failure

When the 0750.147.040 hose pipe degrades, operators typically notice three distinct failure modes. First, external ATF seepage near the WG180 cooler line connections becomes visible, often leaving oily residue on the 4644101134: TRANSMISSION HOUSING. Second, erratic shift timing during load cycles occurs as internal hose wall collapse restricts fluid flow to the clutch packs. Third, audible whining from the pump circuit indicates cavitation caused by air ingestion through micro-cracks in the rubber reinforcement layer. Fourth, overheating during prolonged highway operation signals reduced cooling circuit efficiency, which can accelerate wear on the 4642303097: OUTPUT FLANGE bearings.

Technical Specifications

Compatibility

This hose pipe is primarily validated for the ZF WG180 series, including WG180, WG180C, and WG180E variants used in mobile crane and heavy truck applications. The 0750.147.040 also fits select WG200 transmissions when paired with the correct 0636020211: HEXAGON SCREW kit for bracket mounting. For WG210 and WG250 series, verify the cooler line routing geometry before installation, as the hose bend radius differs. Always replace the mating O-rings (reference 0634303485: O-RING) simultaneously to prevent cross-threading at the disconnection point.
