ZF 2094.303.045 SPLINED BUSH | OEM Genuine Part

Overview

The ZF 2094.303.045 SPLINED BUSH is a critical wear component engineered for the internal gear train of heavy-duty ZF construction machinery transmissions. This OEM genuine part, identified by SKU 2094.303.045, functions as a precision-machined interface between rotating shafts and stationary housings. It absorbs torsional loads and maintains concentric alignment within the transmission’s power flow path. Typically pressed into the transmission casing or planetary carrier, this splined bush supports the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT, ensuring smooth torque transfer during high-stress operations like excavator digging or wheel loader reversing.

Symptoms of Failure

When the ZF 2094.303.045 splined bush begins to degrade, operators may notice these specific failure indicators:

• Transmission gear slipping under load – Worn splines cause the main shaft to lose engagement, leading to intermittent power loss during heavy digging or climbing.
• Metallic grinding noise from the transmission housing – Excessive clearance between the bush and the 2094106010: SHIFT SYSTEM components creates audible chatter during gear changes.
• Oil contamination with bronze or steel particles – Flaking material from the splined bush enters the hydraulic circuit, clogging filters and reducing clutch pack life.
• Hard shifting or gear engagement delay – Binding caused by deformed splines prevents the 2094206001: GEARSHIFT SHAFT from moving freely, resulting in sluggish response times.

Technical Specifications

Compatibility

This splined bush is primarily designed for ZF’s heavy-duty powershift transmission series used in construction machinery. It is a direct fit for the following transmission models:

• ZF WG180 – Common in wheel loaders and telehandlers
• ZF WG200 – Used in medium-sized excavators and graders
• ZF WG210 – Found in large articulated dump trucks
• ZF 4WG-200 – Four-speed variant for industrial tractors

Always verify the spline count and shaft diameter against your existing 2094304054: MAIN SHAFT before installation.
