Overview
The ZF 5838.300.717 CONNECTION PART is a precision-engineered OEM genuine component designed for heavy-duty construction machinery transmissions. This critical interface element sits within the final drive assembly, serving as the mechanical link between the differential housing and the axle shaft system. The SKU 5838.300.717 ensures proper torque transfer and alignment in ZF drivetrains, directly supporting the 2093109003: DIFFERENTIAL and 2093209096: DIFFERENTIAL units. Manufactured to ZF’s stringent tolerances, this connection part maintains structural integrity under extreme loads common in excavators, loaders, and graders.
Symptoms of Failure
- Transmission oil seepage at axle connection points: When the 5838.300.717 connection part wears, hardened seals allow lubricant to escape, creating visible drips near the differential housing.
- Abnormal gear whine during low-speed operation: A worn connection part introduces micro-movement that causes the 0750117075: TAPER ROLLER BEARING to misalign, producing a distinct high-pitched noise under load.
- Intermittent drive disengagement on inclines: Degraded connection geometry leads to temporary loss of torque transfer, particularly when the machine operates on slopes or uneven terrain.
- Vibration through the chassis during acceleration: A failing connection part creates rotational imbalance, felt as rhythmic shaking in the operator cab during gear shifts.

Frequently Asked Questions
Q: Can the 5838.300.717 be replaced without removing the entire transmission?
A: Yes, this connection part is accessible after removing the axle shaft and differential cover. However, we recommend replacing the 0750117075: TAPER ROLLER BEARING simultaneously due to shared wear patterns.
Q: What is the typical service interval for this connection part?
A: In construction machinery operating 2,000-3,000 hours annually, the 5838.300.717 should be inspected every 4,000 hours and replaced at 8,000-hour major overhauls.
Q: Does this part fit both WG180 and WG200 transmissions?
A: Yes, the 5838.300.717 is dimensionally identical for both series, though you must verify the 2093309073: DIFF.HOUSING bolt pattern matches your specific unit.
