ZF 4143.197.001 PACKING | OEM Genuine Part

Overview

The ZF 4143.197.001 PACKING is a critical sealing component engineered for the HL 100 and HL 270 series transmissions. This OEM genuine part ensures a leak-proof interface between the transmission housing and internal fluid passages, preventing contamination and maintaining hydraulic pressure. The SKU 4143.197.001 is specifically designed to withstand high thermal loads and constant vibration found in heavy-duty industrial drivetrains. It sits at the junction of the main casing and auxiliary assemblies, acting as a static seal that isolates oil circuits from external debris.

Symptoms of Failure

When the ZF 4143.197.001 PACKING deteriorates, operators often notice oil weeping around the transmission bell housing or near the PTO mounting points. A second common symptom is erratic gear engagement or delayed shifting caused by pressure loss in the hydraulic control system. You may also detect visible oil streaks on the transmission exterior after extended operation, particularly around the joint between the 4143101043 HOUSING and the 4143298040 CASE. In severe cases, low transmission fluid levels trigger warning lights or overheating, as the packing fails to retain the required oil volume for lubrication.

Technical Specifications

Compatibility

This packing is a direct replacement for ZF transmissions in the HL 100 and HL 270 series, including models such as the WG180, WG200, and WG210. It also fits select variants of the 4WG-200 and 5WG-210 series used in construction and agricultural machinery. Always verify the sealing groove dimensions in your specific transmission assembly. The packing works in conjunction with the 4143301055 HOUSING and the 0631329135 SPRING PIN to secure the seal in place during high-pressure operation.
