Overview
The ZF 2094.211.027 AXLE FLARED TUBE is a precision-engineered hydraulic conduit designed to manage high-pressure fluid transfer within the final drive assembly of heavy-duty construction machinery. This OEM genuine part sits between the axle housing and the transmission sump, ensuring uninterrupted lubrication to critical gear sets. The SKU 2094.211.027 is machined from corrosion-resistant steel to withstand extreme thermal cycling and mechanical vibration. When paired with a robust 2094101017: TRANSMISSION HOUSING, this flared tube maintains consistent oil flow, preventing cavitation and component overheating during prolonged operation in excavators and wheel loaders.
Symptoms of Failure
- Visible hydraulic oil seepage at axle connection points – Worn flare seats or micro-cracks in the tube body cause fluid to weep, leading to gradual pressure loss and transmission overheating.
- Erratic gear engagement under load – A compromised tube reduces lubrication to the differential, producing grinding noises or delayed clutch pack response during heavy digging cycles.
- Contaminated transmission fluid – Cracks in the flared tube allow debris ingress, resulting in sludge buildup that accelerates wear on the 0634303085: O-RING and adjacent seals.
- Sudden loss of axle pressure – Complete tube rupture triggers immediate system shutdown, often accompanied by a low-pressure warning light on the operator dashboard.

Compatibility
This flared tube is engineered for ZF WG180, WG200, and WG310 series transmissions commonly installed in Caterpillar, Komatsu, and Volvo construction equipment. It directly interfaces with the 2094301069: HOUSING and the 2094298054: HOUSING to form a sealed fluid circuit. For proper installation, always replace the 0636302008: SCREW PLUG and inspect the 0750111371: SHAFT SEAL for wear. This part is not backward-compatible with pre-2010 ZF 4WG models without adapter fittings.
