Overview
The ZF 0501.298.296 SEALING SET is a critical OEM genuine gasket and seal kit designed to restore hydraulic integrity within ZF WG-series powershift transmissions. This assembly-level service part contains all necessary elastomeric seals, O-rings, and gaskets required to reseal the transmission housing interfaces. Specifically engineered for the WG115, WG130, and WG158 models, the 0501.298.296 sealing set prevents pressurized oil migration between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring consistent clutch pack lubrication and torque converter pressure. This kit is the primary solution for addressing fluid loss at the main case joints.
Symptoms of Failure
- External oil seepage at housing split lines: Visible wetness or drips forming between the HOUSING REAR PART and the main transmission case, often noticed after extended operation.
- Gradual transmission fluid level drop without visible puddles: Internal seal failure allows oil to bypass into the bell housing or converter area, leading to low sump levels and potential pump cavitation.
- Delayed engagement or clutch chatter: Worn seals in the sealing set cause pressure loss to specific clutch packs, resulting in soft shifts or erratic engagement under load.
- Cross-contamination of oil circuits: Failed internal gaskets allow mixing of lube oil with converter charge oil, causing overheating and reduced transmission efficiency.
