ZF 2093.247.059 TUBE | OEM Genuine Part

Overview

The ZF 2093.247.059 TUBE is a precision-engineered hydraulic or lubrication conduit integral to the internal oil circulation system of heavy-duty ZF powershift transmissions. Positioned within the valve body or clutch housing assembly, this OEM genuine part directs pressurized transmission fluid to critical lubrication points, ensuring consistent cooling and hydraulic actuation. The SKU 2093.247.059 is manufactured to exact ZF tolerances, guaranteeing a leak-free seal and uninterrupted fluid flow under extreme load conditions common in construction machinery.

Symptoms of Failure

• Transmission fluid leaks near the valve body: A cracked or corroded 2093.247.059 tube often causes visible oil seepage, leading to low fluid levels and eventual overheating.
• Erratic gear engagement or slipping: When this tube becomes blocked or deformed, hydraulic pressure drops, resulting in delayed clutch pack engagement and gear slippage during heavy operation.
• Whining or cavitation noise from the transmission: Restricted oil flow through a damaged tube creates air entrainment, producing a high-pitched whine that worsens under load.
• Overheating of the transmission housing: Inadequate lubrication due to a compromised tube causes localized hot spots, often triggering thermal warning sensors on construction equipment.

Technical Specifications

Compatibility

This tube is designed for ZF WG series powershift transmissions commonly found in wheel loaders, dozers, and graders. It is a direct fit for the WG180, WG200, and WG210 models, as well as select 4WG-200 and 6WG-200 variants used in construction machinery from manufacturers like Caterpillar, Volvo, and Case. Always verify your transmission serial number before installation.

Related Components

When replacing the 2093.247.059 TUBE, it is common practice to also inspect the 0750117075 TAPER ROLLER BEARING for wear, as bearing debris can obstruct the tube. Additionally, the 2093109002 DIFFERENTIAL and 2093209095 DIFFERENTIAL units rely on proper oil flow from this tube to maintain lubrication. The 2093309071 DIFF.HOUSING must also be free of cracks to prevent fluid bypass.

Frequently Asked Questions

Q: Can a damaged 2093.247.059 tube cause complete transmission failure?
A: Yes. If this tube ruptures or becomes fully blocked, oil starvation can lead to clutch pack seizure and catastrophic gear damage within hours of operation.

Q: Is the 2093.247.059 tube interchangeable with aftermarket versions?
A: We strongly recommend using only the OEM genuine part. Aftermarket tubes often have thinner walls or incorrect bend angles, which can cause vibration-induced fatigue and premature failure.

Q: How often should this tube be replaced during transmission rebuilds?
A: Always replace the tube during any major transmission overhaul. Even if it appears intact, microscopic stress fractures can develop over 10,000+ hours of service.
