TM1399 John Deere 570B Motor Grader Pdf Diagnostic, Operation and Test Service Manual

John Deere 570B Motor Grader Operation & Test Technical Manual (TM1399)

Troubleshooting a classic machine like the John Deere 570B Motor Grader requires a different mindset than modern equipment. There are no computer ports to plug into; instead, you rely on pressure gauges, flow meters, and multimeters. The John Deere 570B Operation and Test Manual (TM1399) is the "detective's handbook" for this generation of iron. While the Repair Manual (TM1400) tells you how to take it apart, this manual tells you where to look when it isn't working right. It provides the hydraulic flow maps and electrical circuit diagrams necessary to trace a problem from symptom to source without turning a single bolt unnecessarily.

If your 570B is suffering from "spongy" blade controls, overheating hydraulics, or a transmission that hesitates between gears, this manual provides the system logic and testing procedures to diagnose the issue. It details the exact pressure settings for relief valves and the voltage specs for the charging system. With TM1399, you stop guessing which part is broken and start proving it with data, saving both time and money on parts.

System Analysis & Troubleshooting

Hydraulic System Logic & Pressure Testing

The 570B lives and dies by its hydraulic pressure. This manual offers comprehensive hydraulic flow schematics that show exactly how fluid moves through the control valves, steering orbitrol, and articulation cylinders. It includes detailed pressure testing ports and specifications, allowing you to hook up a gauge and verify if the main pump is delivering the correct PSI or if a relief valve is popping too early. This is critical for diagnosing low power or slow cycle times.

Electrical Circuit Tracing

Even without computers, the 570B has a vital electrical network. TM1399 provides clear, easy-to-read wiring diagrams for the starting, charging, and lighting circuits. Whether you are chasing a battery drain, a faulty starter solenoid, or gauges that won't read, these diagrams map out every wire color and connection point. It simplifies the process of restoring the electrical integrity of an older machine where wires may be faded or modified over time.

Operational Checkout & Adjustment

How do you know if your 570B is performing as it did when it left the factory? This manual outlines the Operational Checkout procedures. These are step-by-step tests to verify engine speed, transmission shift points, and brake holding power. It guides you through the adjustment of control linkages and valve spools, helping you fine-tune the machine's response so it grades smoothly and predictably.

Who Needs This Diagnostic Manual?

• Vintage Equipment Mechanics: Troubleshooting systems without OBD scanners.
• Owner-Operators: Who want to maintain peak performance on their legacy machines.
• Restoration Projects: needing to re-wire or re-plumb a 570B from scratch.
• Field Service Techs: Who need quick access to pressure specs on the job site.
