ZF 4699.270.011 ASSEMBLY PARTS | OEM Genuine Part

Overview

The ZF 4699.270.011 ASSEMBLY PARTS is a critical internal component designed for heavy-duty powershift transmissions used in construction machinery. This OEM genuine part, identified by SKU 4699.270.011, functions as a precision-machined assembly that manages hydraulic flow and mechanical engagement within the transmission housing. It sits directly adjacent to the 4699101079: HOUSING, ensuring proper alignment and sealing of the gear train. Without this assembly, the transmission cannot maintain consistent pressure for clutch packs or torque converter operation.

Symptoms of Failure

When the 4699.270.011 assembly wears out, operators typically encounter these specific failure modes:

• Erratic gear engagement or delayed shifting – The assembly loses its ability to regulate hydraulic pressure, causing harsh or slow shifts under load.
• Internal transmission oil leaks – Worn mating surfaces allow fluid to bypass the 0634306309: O-RING, leading to visible drips from the bell housing.
• Overheating during low-speed operation – Reduced oil flow from a failing assembly causes friction plates to overheat, often accompanied by a burnt smell.
• Whining or grinding noises from the transmission – Metal-on-metal contact occurs when the assembly no longer maintains proper clearance with the 0501329881: HOUSING COVER.

Technical Specifications

Compatibility

This assembly is engineered for ZF powershift transmissions commonly found in wheel loaders, dozers, and excavators. It is directly compatible with the following transmission models:

• ZF WG180 – Used in medium-duty construction loaders
• ZF WG200 – Found in heavy articulated dump trucks
• ZF 4WG-200 – Variant with integrated torque converter
• ZF 6WG-250 – High-torque applications for mining equipment

During installation, always replace the 0637885612: BREATHER to prevent pressure buildup that could damage the new assembly.
