ZF 4699.025.015 GP25 | OEM Genuine Part

Overview

The ZF 4699.025.015 GP25 is a precision-engineered OEM genuine part designed for integration within the clutch pack assembly of heavy-duty ZF transmissions used in construction machinery. This component, identified by SKU 4699.025.015, functions as a critical pressure plate or reaction plate, ensuring consistent clamping force and smooth power transfer between rotating gears. It sits directly between the piston and friction discs, managing hydraulic pressure to prevent slippage under extreme loads. When paired with the 4699101156 HOUSING and the 4699201019 HOUSING, this part forms a sealed, high-torque assembly that withstands the rigors of earthmoving and material handling equipment.

Symptoms of Failure

When the ZF 4699.025.015 GP25 wears out, operators often notice intermittent gear slipping under load, especially during uphill travel or heavy digging. Another common sign is delayed engagement when shifting from neutral to drive, accompanied by a harsh shudder. You may also detect metallic debris in the transmission oil filter due to surface spalling. Finally, erratic hydraulic pressure fluctuations can occur, leading to overheating and reduced machine productivity. Addressing these issues promptly prevents damage to the 4699309078 HOUSING COVER and surrounding seals.

Technical Specifications

Compatibility

This GP25 plate is engineered for ZF WG180, WG200, and WG210 series transmissions commonly found in wheel loaders, graders, and excavators. It also fits select 4WG-200 and 6WG-200 variants used in agricultural tractors. Always verify your transmission model tag before ordering. For secure installation, use the 0636100132 TORX SCREW to fasten the assembly to the piston hub.
