ZF 0750.115.357 NEEDLE CAGE | OEM Genuine Part

Overview

This OEM genuine ZF 0750.115.357 NEEDLE CAGE is a precision-engineered component designed to maintain proper roller alignment within the planetary gear sets of heavy-duty construction machinery transmissions. Positioned between the sun gear and planet gears, this needle cage reduces friction and distributes load evenly across the bearing assembly. The SKU 0750.115.357 is manufactured to ZF’s exacting tolerances, ensuring consistent torque transfer and extended service life in demanding environments such as wheel loaders, graders, and dozers. When paired with a 5838109012: DIFFERENTIAL, this needle cage supports the entire drivetrain’s rotational stability.

Symptoms of Failure

• Gear whining or grinding noise during acceleration: A worn 0750.115.357 needle cage allows rollers to shift, creating metal-on-metal contact within the planetary set.
• Intermittent gear slipping under load: When the cage loses structural integrity, roller spacing becomes irregular, causing momentary loss of torque transfer in the transmission.
• Metallic debris in transmission fluid: Fractured cage fragments contaminate the oil, often visible during routine drain intervals, indicating imminent bearing failure.
• Vibration at specific RPM ranges: Uneven roller distribution from a deformed needle cage produces harmonic vibrations that resonate through the driveline.

Technical Specifications

Compatibility

This needle cage is engineered for ZF’s WG180, WG200, and WG211 series transmissions commonly found in construction machinery. It also fits select variants of the ZF 4WG-200 and 6WG-200 power shift transmissions. For complete drivetrain assembly, this part integrates directly with the 0750117075: TAPER ROLLER BEARING and the 2093209023: DIFFERENTIAL to ensure proper axial load management. The 5838300626: DIFFERENTIAL HOUSING provides the necessary enclosure for this needle cage assembly.

Frequently Asked Questions

Q: How can I confirm the 0750.115.357 needle cage fits my ZF transmission?
A: Verify your transmission model plate—this cage is standard in WG180, WG200, and WG211 series. Measure the existing cage’s outer diameter (68.5 mm) and width (22.0 mm) to confirm compatibility.

Q: Can a damaged needle cage cause damage to other drivetrain components?
A: Yes. A fractured cage often leads to roller misalignment, which can score the sun gear and planet gear surfaces. It may also contaminate the 5838300626: DIFFERENTIAL HOUSING with metal debris, requiring a full overhaul.

Q: Should I replace the taper roller bearing at the same time as the needle cage?
A: ZF recommends replacing the 0750117075: TAPER ROLLER BEARING simultaneously, as both components share load paths and wear patterns in the planetary assembly.
