Overview
The ZF 0501.223.084 HOSE PIPE is a critical fluid transfer component engineered for the WG260 and WG310 series transmissions. This OEM genuine part routes pressurized hydraulic oil between the valve body and the cooler circuit, ensuring consistent lubrication and thermal regulation within the gear train. As a direct replacement for the original equipment, the SKU 0501.223.084 guarantees factory-specified flow rates and pressure tolerances. When installed alongside the 4646101167 TRANSMISSION HOUSING, this hose pipe maintains the sealed integrity of the hydraulic loop, preventing contamination ingress and maintaining shift quality under heavy load.
Symptoms of Failure
- Hydraulic fluid seepage at hose connections: Visible oil residue around the pipe ends or along the hose body indicates micro-cracking or fitting degradation, leading to gradual fluid loss.
- Erratic gear engagement or delayed shifts: A compromised hose pipe reduces line pressure, causing hesitation when shifting between forward and reverse ranges, especially under load.
- Overheating transmission oil: Restricted flow through a collapsed or internally delaminated hose pipe starves the cooler, resulting in elevated sump temperatures and potential thermal damage.
- Audible whining or cavitation noise: Air ingestion through a cracked hose pipe produces a high-pitched sound from the pump, signaling imminent hydraulic system failure.

Compatibility
This hose pipe is specifically designed for ZF WG series powershift transmissions. Primary applications include the WG260 and WG310 models used in construction and agricultural machinery. It is also compatible with the WG180 and WG200 series when used in the cooler return circuit. For proper installation, ensure the 4646301317 HOUSING is free of debris and the 0636115293 螺栓 are torqued to factory specifications. Always pair this hose pipe with new 0636101153 CAP SCREW fasteners to prevent thread galling.
