ZF 0750.115.400 NEEDLE SLEEVE | OEM Genuine Part

Overview

The ZF 0750.115.400 NEEDLE SLEEVE is a precision-engineered OEM genuine component designed to reduce rotational friction and support radial loads within the planetary gear sets of heavy-duty ZF transmissions. This needle sleeve acts as a low-friction bearing surface between rotating shafts and stationary housings, ensuring smooth power transfer in construction machinery drivetrains. The SKU 0750.115.400 is specifically calibrated for high-torque applications where thermal expansion and load cycling are constant. When installed alongside the 5838109007: DIFFERENTIAL, it maintains proper gear alignment and prevents metal-to-metal contact that can lead to premature wear.

Symptoms of Failure

• Transmission whining noise during acceleration: A worn 0750.115.400 needle sleeve allows shaft play, producing a high-pitched metallic whine that intensifies under load.
• Intermittent gear slippage in lower ratios: As the sleeve loses its surface hardness, the 0750117075: TAPER ROLLER BEARING experiences uneven loading, causing momentary power loss.
• Oil contamination with bronze or steel particles: Flaking from the needle sleeve surface mixes with transmission fluid, often visible during routine drain intervals.
• Vibration in the driveline at idle: Excessive clearance from a collapsed sleeve creates harmonic vibrations that resonate through the 2095209019: DIFFERENTIAL assembly.

Technical Specifications

Compatibility

This needle sleeve is a direct-fit component for ZF WG180, WG200, and WG250 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It also applies to select ZF Ecomat 4HP and 5HP models where the planetary carrier requires a low-friction interface. For proper installation, ensure the 0631329086: SPRING PIN is replaced simultaneously to secure the sleeve in its bore. Always verify clearance with the mating shaft before final assembly.
