ZF 2094.303.047 SPLINED BUSH | OEM Genuine Part

Overview

The ZF 2094.303.047 SPLINED BUSH is a critical wear component engineered for the internal gear train of heavy-duty construction machinery transmissions. This OEM genuine part, identified by SKU 2094.303.047, serves as a precision-machined interface between rotating shafts and stationary housings. It is specifically designed to absorb radial loads and maintain concentric alignment within the planetary gear sets. In a ZF transmission, this splined bush sits directly on the 2094104412: MAIN SHAFT, providing a durable bearing surface that reduces friction and prevents metal-to-metal contact during high-torque operations.

Symptoms of Failure

When the ZF 2094.303.047 SPLINED BUSH begins to degrade, operators will notice distinct performance issues. Look for these specific failure indicators:

• Erratic gear engagement and slipping: Worn splines cause the 2094106010: SHIFT SYSTEM to lose positive engagement, resulting in delayed or incomplete gear shifts under load.
• Metallic grinding noises from the transmission housing: As the bush wears, the 2094206001: GEARSHIFT SHAFT may contact the housing, producing a distinct scraping sound during operation.
• Oil contamination with bronze or steel particles: Degraded bush material mixes with transmission fluid, causing filter clogging and accelerated wear on the 2094304054: MAIN SHAFT.
• Increased axial play in the driveline: Excessive clearance between the bush and shaft leads to noticeable vibration, especially when shifting between forward and reverse gears.

Technical Specifications

Compatibility

This splined bush is a direct-fit component for several ZF heavy-duty transmission models commonly found in construction machinery. It is primarily used in the WG180 and WG200 series, as well as the WG210 and WG220 variants. The part also appears in certain Ecomat 4HP and 6HP off-highway transmissions. Always verify the spline count and shaft diameter against your existing 2094304054: MAIN SHAFT before installation to ensure proper fitment.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “In most ZF WG180 and WG200 transmissions, the splined bush can be replaced by removing the gearshift shaft and main shaft access covers. However, full transmission removal is recommended if the shaft or shift system shows signs of damage.”
