The Leak Tester Tool is used to assemble with a pressure test pump group to inspect the cooler and controlled start transmission gearboxes for leakage during disassembly and assembly procedures. It forms a secure interface between the pressure source and the gearbox passages, enabling accurate pressurization for inspection without disturbing internal alignment. The tool supports stable pressure application so technicians can monitor sealing areas, joints, and connection points under controlled conditions.Attributes:• Direct fit interface with pressure test pump assembly unit.• Supports controlled internal gearbox pressurization tasks.• Enables accurate leak detection during service checks.Applications: The Leak Tester Tool connects with the pressure test pump group to inspect the cooler and controlled start transmission gearboxes for leakage during assembly and disassembly procedures.
