ZF 2093.313.093 OIL FEEDING RING | OEM Genuine Part

Overview

The ZF 2093.313.093 OIL FEEDING RING is a precision-engineered OEM genuine component responsible for directing pressurized lubricant to critical bearing surfaces and gear meshes within the transmission sump. Positioned directly on the main shaft assembly, this ring acts as a hydraulic distributor, ensuring consistent oil flow to the 5838109009: DIFFERENTIAL and adjacent planetary sets. Without proper oil channeling, internal temperatures rise rapidly, leading to premature wear. The SKU 2093.313.093 is manufactured to exact ZF tolerances, making it a direct replacement for failed or worn units in heavy-duty construction machinery transmissions.

Symptoms of Failure

• Intermittent gear slipping under load: When the oil feeding ring cracks or distorts, hydraulic pressure drops, causing the 0750117075: TAPER ROLLER BEARING to run dry, resulting in momentary power loss during excavation or grading.
• Visible oil leaks near the transmission bell housing: A worn sealing surface on the ring allows ATF to bypass the intended circuit, pooling around the 5838300626: DIFFERENTIAL HOUSING and creating a telltale drip pattern.
• High-frequency whining noise from the gear train: Insufficient lubrication causes metal-on-metal contact, producing a distinct whine that increases with RPM, often misdiagnosed as a failing 2093209023: DIFFERENTIAL unit.
• Overheating transmission fluid: Restricted oil flow through a deformed ring elevates sump temperatures beyond 120°C, triggering warning lights on modern construction equipment dashboards.

Technical Specifications

Compatibility

This oil feeding ring is designed for ZF WG180, WG200, and WG310 series transmissions commonly found in wheel loaders, telehandlers, and excavators from manufacturers such as Liebherr, Caterpillar, and Volvo CE. It also fits select ZF 4WG-200 and 6WG-310 variants used in mining trucks and graders. Always verify the transmission serial number before ordering, as minor revisions exist between early and late production runs.

Frequently Asked Questions

Q: Can a worn oil feeding ring cause transmission shudder?
A: Yes. When the ring fails to meter oil evenly to the clutch packs, hydraulic pressure fluctuates, producing a pronounced shudder during low-speed maneuvering in construction equipment.

Q: Is the 2093.313.093 ring interchangeable with the 2093.313.092 variant?
A: No. The .093 revision has a modified oil groove depth and a wider sealing land. Using the older .092 ring may result in insufficient lubrication to the 5838300811: THRUST WASHER and subsequent scoring.

Q: How often should this ring be replaced during a rebuild?
A: Always replace the oil feeding ring whenever the transmission is disassembled for bearing or differential work. The ring’s sintered material can develop micro-cracks invisible to the naked eye, leading to early failure if reused.
