ZF 4699.298.004 REPAIR KIT | OEM Genuine Part

Overview

The ZF 4699.298.004 REPAIR KIT is a critical OEM genuine service assembly designed to restore sealing integrity and mechanical precision within heavy-duty ZF transmissions used in construction machinery. This kit contains all necessary gaskets, seals, and wear components required to overhaul the hydraulic control section and clutch piston area. Specifically, the SKU 4699.298.004 addresses the interface between the main valve body and the pump drive housing, ensuring proper oil pressure regulation and preventing cross-contamination between circuits. When installed alongside the 4699101018: HOUSING and the 4699301051: HOUSING, this repair kit guarantees a leak-free seal at the transmission’s high-pressure junction.

Symptoms of Failure

• External oil seepage at the transmission bell housing: When the 4699.298.004 kit’s gaskets degrade, pressurized ATF escapes past the mating surfaces, leaving visible drips on the chassis after shutdown.
• Erratic clutch engagement or delayed shifting: Worn seals inside this repair kit cause internal pressure loss, leading to soft shifts or complete failure of a specific gear range during loader operation.
• Contaminated transmission fluid with metallic debris: A failing kit allows debris from the torque converter to bypass the filter circuit, accelerating wear on the 4699301054: HOUSING COVER and adjacent valve bores.
• Audible hydraulic whine under load: Air ingestion through deteriorated O-rings in the kit produces cavitation noise, particularly when the machine is digging or climbing grades.

Technical Specifications

Compatibility

This repair kit is engineered for ZF WG180, WG200, and WG211 series powershift transmissions commonly installed in wheel loaders, dozers, and telehandlers from manufacturers such as Caterpillar, Volvo, and JCB. It also fits select ZF 4WG-200 and 6WG-200 variants where the control housing uses the same bolt pattern and seal groove dimensions. Always verify the existing 4699301055: COVER part number before ordering to ensure correct fitment.
