TM2313 John Deere 655C, 755C Series II Crawler Loaders Pdf Diagnostic, Operation and Test Service Manual

John Deere 655C, 755C Series II Crawler Loaders Diagnostic, Operation & Test Service Manual (TM2313)

The "Series II" designation on a John Deere 655C or 755C represents a refinement in hydrostatic control and operator response. However, these advancements mean that when a tracking issue arises or a warning light flashes, the root cause is often buried in the electronic logic rather than a broken gear. The John Deere 655C & 755C Series II Operation and Test Manual (TM2313) is the specialized tool required to navigate this updated architecture. It moves beyond mechanical repair to focus exclusively on System Diagnostics, Electronic Circuit Analysis, and Hydrostatic Logic.

For the technician maintaining these specific Series II machines, TM2313 is indispensable. It provides the Diagnostic Trouble Codes (DTCs) unique to the Series II controllers and the calibration procedures necessary to keep the dual-path hydrostatic drive synchronized. Whether you are troubleshooting a "limp mode" condition or tracing a voltage drop in the joystick harness, this manual provides the data to pinpoint the failure without guesswork.

Solving Series II Electronic & Hydraulic Issues

Hydrostatic Logic & Code Interpretation

The 655C/755C Series II relies on a complex interaction between the engine speed and the hydrostatic pump displacement. This manual contains the complete DTC index for the Series II controllers. It guides you through the logic tree to identify the root cause of a fault—be it a speed sensor, a pressure transducer, or the controller itself. Crucially, it details the calibration procedures required to "teach" the system how to behave after a component replacement, ensuring smooth, predictable tracking.

Electrical Schematic Tracing

Aging wiring harnesses can cause intermittent faults that baffle even experienced mechanics. TM2313 provides high-resolution, color-coded wiring diagrams that map every circuit in the Series II loaders. From the engine ECU to the cab controls, you can trace power and signal paths with absolute clarity. The manual includes connector end views and pin-out charts, allowing you to probe connectors with confidence and verify voltage readings against factory specifications.

System Operational Checkout

Before the loader returns to the job site, it must be verified. This manual outlines the Operational Checkout procedures used by factory technicians. It covers specific tests for hydraulic cycle times, bucket drift, and track speed synchronization. By following these standardized tests, you can quantitatively prove that the repair was successful and that the machine is performing to Series II standards.

Series II Diagnostic FAQ

Does this manual explain how to calibrate the hydrostatic drive?

Yes, it includes the step-by-step calibration procedures for the pumps and motors, which is mandatory after replacing any hydrostatic component on a Series II machine.

I have a code for the track speed sensor. Is the test procedure included?

Absolutely. The manual lists the DTCs and provides the electrical testing sequence to verify the sensor and its circuit.

Can I see the hydraulic flow diagrams?

Yes. The manual includes hydraulic flow schematics that verify the logic of the hydrostatic system and the loader hydraulics.

Does this cover engine mechanical repair?

No. This manual covers engine diagnostics (codes and sensors). For physical engine disassembly, you need the Repair Manual or Engine CTM.
