Overview
The ZF 2095.217.019 TUBE is a precision-engineered hydraulic fluid conduit designed for heavy-duty construction machinery transmissions. This OEM genuine part routes pressurized oil between the valve body and the differential assembly, ensuring consistent lubrication and clutch actuation within the transmission sump. As a critical component in the lubrication circuit, the 2095.217.019 tube maintains proper fluid flow to the 2095109009: DIFFERENTIAL and surrounding gear sets. Constructed from corrosion-resistant steel, this tube withstands high thermal cycling and vibration common in excavators and wheel loaders.
Symptoms of Failure
- Hydraulic oil seepage at transmission housing: A cracked or corroded 2095.217.019 tube often causes slow drips near the differential housing, leading to low fluid levels over time.
- Erratic gear engagement under load: Restricted oil flow from a blocked tube results in delayed clutch pack pressurization, causing harsh shifts or slipping during heavy excavation.
- Overheating transmission sump: Insufficient lubrication due to a compromised tube forces the 0750117075: TAPER ROLLER BEARING and other rotating elements to run dry, generating excess heat.
- Whining noise from differential area: Air ingestion through a fractured tube creates cavitation, producing a distinct high-pitched whine during operation.

Compatibility
This tube is engineered for ZF WG-series powershift transmissions commonly used in construction machinery. It directly fits the WG180, WG200, and WG211 models, where it connects the main control valve to the 2095209037: DIFFERENTIAL assembly. It also appears in select WG150 and WG250 variants used in telescopic handlers and graders. Always verify the tube routing against the 2095309059: DIFF.HOUSING to ensure proper alignment with the axle bevel gear set.
