ZF 0750.115.408 NEEDLE SLEEVE | OEM Genuine Part

Overview

This OEM genuine ZF 0750.115.408 NEEDLE SLEEVE is a precision-engineered component designed to reduce friction and support radial loads within the planetary gear sets of heavy-duty ZF transmissions. Positioned between rotating shafts and stationary housings, this needle sleeve ensures smooth torque transfer and minimizes wear on adjacent parts. The SKU 0750.115.408 is a critical element in the differential assembly, where it works in concert with the 5838109012: DIFFERENTIAL and the 2093209023: DIFFERENTIAL to manage load distribution. Without a properly functioning needle sleeve, the entire gear train experiences accelerated degradation, making this part indispensable for maintaining transmission integrity in construction machinery.

Symptoms of Failure

When the ZF 0750.115.408 NEEDLE SLEEVE wears out, operators will notice distinct performance issues. Transmission whining noise under load is a primary indicator, as the worn sleeve fails to dampen vibration between rotating components. Intermittent gear slipping during acceleration occurs when the needle rollers lose their alignment, causing momentary power loss. Metallic debris in the transmission fluid signals that the sleeve surface has spalled, contaminating the oil and threatening the 0750117075: TAPER ROLLER BEARING. Finally, localized overheating near the differential housing can develop as friction increases, potentially warping the 5838300626: DIFFERENTIAL HOUSING if left unaddressed.

Technical Specifications

Compatibility

This needle sleeve is engineered for use in ZF heavy-duty transmissions commonly found in construction machinery. Based on its design and dimensions, the 0750.115.408 is compatible with the following ZF model series: WG180, WG200, WG250, and WG310. It is also used in certain ZF Ergopower and ZF Ecomid drivelines where needle bearings support planetary gear sets. For precise fitment, always verify the part number against your transmission’s serial plate, as variations exist between early and late production runs.

Frequently Asked Questions

Q: How do I know if the 0750.115.408 needle sleeve needs replacement?
A: Listen for a high-pitched whine from the transmission during operation, especially under load. Also check for metal particles in the oil filter or drain plug magnet, which indicate sleeve spalling.

Q: Can I reuse the old needle sleeve if it looks clean?
A: No. Needle sleeves are single-use components due to their precision fit. Even minor wear alters clearances, leading to premature failure of the 5838109012: DIFFERENTIAL and surrounding bearings.

Q: Is this part compatible with ZF WG200 transmissions from 2010?
A: Yes, the 0750.115.408 is used in WG200 series transmissions manufactured between 2005 and 2018. Always cross-reference your transmission serial number to confirm.
