ZF 0730.513.395 SNAP RING | OEM Genuine Part

Overview

The ZF 0730.513.395 SNAP RING is a precision-engineered OEM genuine retaining component designed for heavy-duty construction machinery transmissions. This snap ring functions as a critical axial locking mechanism, securing gear assemblies and bearing packs in their precise positions within the transmission housing. Specifically, the 0730.513.395 snap ring sits within a machined groove on the output shaft or differential carrier, preventing lateral movement of adjacent components under extreme torque loads. As an OEM genuine part, it ensures exact fitment and material integrity, eliminating the risk of premature failure that often accompanies aftermarket alternatives. This part is commonly paired with the 5838109012: DIFFERENTIAL assembly to maintain proper gear mesh alignment.

Symptoms of Failure

• Transmission oil leaks at shaft seals: When the snap ring fatigues or breaks, axial play allows the shaft to shift, distorting seal lips and causing external fluid seepage around output flanges.
• Intermittent gear slipping under load: A worn or dislodged snap ring permits gear clusters to drift out of their intended engagement zone, resulting in momentary power loss during excavation or grading operations.
• Metallic grinding noises from differential area: Broken snap ring fragments can migrate into the 2093209023: DIFFERENTIAL gearset, causing audible chatter or grinding during turns.
• Excessive end-play in output shaft: Measurable axial movement at the yoke or flange indicates the snap ring has lost its retaining capacity, often accompanied by vibration at highway speeds.

Technical Specifications

Compatibility

This snap ring is engineered for ZF heavy-duty powershift transmissions commonly found in construction machinery. Based on its dimensional profile and groove design, the 0730.513.395 is compatible with the following ZF transmission models: WG180, WG200, WG210, and select variants of the Ergopower series. It is also used in certain differential housings such as the 5838300626: DIFFERENTIAL HOUSING assembly. For applications involving the 0750117075: TAPER ROLLER BEARING, this snap ring provides the necessary preload retention to maintain bearing clearance specifications.

Frequently Asked Questions

Q: Can I reuse the 0730.513.395 snap ring after disassembly?
A: No. ZF recommends always replacing snap rings with new OEM genuine parts. The spring steel loses tension after initial installation, and reusing it risks groove damage or sudden failure under load.

Q: What tools are needed to install this snap ring?
A: You will need snap ring pliers with 90-degree tips and a diameter range of 80-100 mm. Always verify the ring fully seats into the groove by rotating it after installation.

Q: Does this snap ring fit the WG180 transmission with a differential lock?
A: Yes, the 0730.513.395 is compatible with WG180 models equipped with a differential lock, provided the 5838300626: DIFFERENTIAL HOUSING uses the standard groove dimensions.
