When connected in line, the OTC Heavy-Duty Power Steering Pump Analyzer, No. 5079, will isolate the failed components in just minutes. There is no wasted time as in trial and error methods. This universal analyzer measures both the flow and pressure: one to 10 gallons oil flow and up to 3,000 psi of pressure. The set is complete with high pressure hoses, 9/16"-18 standard fittings, and quick disconnect couplers to handle Eaton/Vickers, TRW, Ross and Shepard power steering systems.
