There is only one way to troubleshoot problem components in a heavy-duty power steering system: a flow and pressure reading meter. OTC' No. 5079 measures both: 1 to 10 gallons oil flow and up to 3,000 psi of pressure.
When connected in line, this universal analyzer will isolate the failed components in just minutes. There is no wasted time as in trial and error methods.
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.
