ZF 4644.252.014 SPUR GEAR for WG200 | OEM Genuine Part

Overview

The ZF 4644.252.014 SPUR GEAR is a critical OEM genuine component engineered specifically for the WG 200 Series transmission. This precision-machined gear is responsible for transferring rotational force between parallel shafts within the gear train, ensuring smooth power delivery and load distribution. Positioned within the intermediate shaft assembly, the spur gear (SKU: 4644.252.014) directly interfaces with the 4460115043: HOUSING to maintain correct gear mesh alignment. Its hardened tooth profile is designed to withstand high torque loads and continuous operation in heavy-duty industrial applications.

Symptoms of Failure

When the ZF 4644.252.014 spur gear begins to degrade, operators typically notice these specific failure indicators:

• Whining or grinding noise during gear engagement – Worn tooth surfaces create irregular contact patterns, producing audible metallic sounds under load.
• Vibration through the driveline – As gear teeth wear unevenly, rotational imbalance transmits vibration to the 4469315012: AXLE DRIVE HOUSING and connected components.
• Intermittent power loss or gear slippage – Chipped or pitted teeth fail to maintain positive engagement, causing momentary torque interruptions.
• Metal particles in transmission fluid – Accelerated wear generates ferrous debris that circulates through the lubrication system, often contaminating the 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING.

Technical Specifications

Compatibility

This genuine ZF spur gear is primarily designed for the WG 200 Series transmission family. Based on its tooth geometry and mounting dimensions, it is also compatible with the WG 180 and WG 210 models that share the same intermediate shaft configuration. The gear interfaces directly with the 4460115043: HOUSING and requires proper preload adjustment using the 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING for optimal service life. Always verify your transmission serial number before ordering.
