ZF 0735.300.723 NEEDLE SLEEVE | OEM Genuine Part

Overview

The ZF 0735.300.723 NEEDLE SLEEVE is a precision-engineered bearing component designed to reduce rotational friction between shafts and housings within ZF heavy-duty transmissions. This OEM genuine part, identified by SKU 0735.300.723, is critical for maintaining proper shaft alignment and load distribution in construction machinery drivetrains. It sits directly inside the 2094101019 TRANSMISSION HOUSING, where it supports planetary gear sets and countershafts. Without this needle sleeve, metal-to-metal contact accelerates wear on adjacent components like the 0899325353 HOUSING and 2094298058 HOUSING, leading to premature transmission failure.

Symptoms of Failure

When the 0735.300.723 needle sleeve wears out, operators often notice these specific failure indicators:

• Transmission gear slipping under load – Worn needles allow excessive shaft play, causing gears to disengage during heavy operation.
• Metallic grinding noise from the transmission housing – Failed needle bearings create audible scraping as metal surfaces contact the 2094301071 COVER.
• Oil leaks near the shaft seal area – Excessive radial movement damages the adjacent seal, allowing hydraulic fluid to escape past the 0750111371 SHAFT SEAL.
• Increased operating temperature – Friction from a collapsed sleeve generates heat, often detectable through the housing wall.

Technical Specifications

Compatibility

This needle sleeve is primarily used in ZF WG series transmissions common in construction machinery. Based on its dimensions and application, it fits the following models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF WG310
• ZF Ecolife (selected variants)

Always verify fitment by cross-referencing your transmission serial number with the 0735.300.723 part number. For housing repairs, inspect the 2094298058 HOUSING for scoring before installation.
