ZF 4108.012.112 P 3200 | OEM Genuine Part

Overview

The ZF 4108.012.112 P 3200 is an OEM genuine internal component engineered for the high-torque planetary gear sets found in heavy-duty construction machinery transmissions. This precision-machined part functions as a critical load-bearing element within the main shaft assembly, ensuring consistent power transfer from the torque converter to the output drive. Designated under SKU 4108.012.112, this component is manufactured to ZF’s original factory tolerances, making it a direct replacement for worn units in demanding excavator and wheel loader applications. When installed, it works in concert with the 4108101093 HOUSING and the 4108201177 HOUSING to maintain proper gear alignment and oil flow within the transmission case.

Symptoms of Failure

• Delayed engagement under load: When the 4108.012.112 wears, operators often notice a hesitation of 2-3 seconds before the machine moves forward or reverse, particularly on inclines.
• Low hydraulic pressure warnings: A failing unit can cause internal leakage, triggering dashboard pressure alerts and erratic clutch pack behavior.
• Metallic debris in transmission oil: Worn splines or bearing surfaces shed fine metal particles, visible during routine oil changes or when inspecting the 0501313402 DRAIN VALVE.
• Audible grinding from the bell housing: As clearances increase, a distinct metallic chatter occurs during gear shifts, often accompanied by vibration through the chassis.

Technical Specifications

Compatibility

This genuine ZF part is designed for integration into the WG180, WG200, and WG210 series transmissions commonly used in construction machinery. It also fits select variants of the Ecolife (6HP) series when used with the appropriate 0636302056 SCREW PLUG for port sealing. Always verify your transmission’s serial number against the ZF parts catalog before ordering. The 4108.012.112 is not compatible with older ZF 4WG-65 or 4WG-80 models without additional adapter kits.
