Description

John Deere 310L Backhoe Loader Operation & Test Technical Manual TM14156X19

This is the complete John Deere 310L Backhoe Loader Operation & Test Technical Manual, document number TM14156X19, published 28FEB20. It is the diagnostic and testing companion volume to the repair manual — the book a technician opens when a machine needs to be diagnosed, tested, adjusted, or repaired and returned to work. Coverage spans every major system on the 310L, from the engine control unit through the power shift transmission, open-center hydraulics, electrical harnesses and cab HVAC, and includes full diagnostic trouble code (DTC) procedures, system functional schematics, wiring diagrams, hydraulic schematics, and step-by-step test procedures with specification values.

The 310L Backhoe Loader Operation & Test Technical Manual TM14156X19 is written for machines with product identification numbers (PIN) beginning 1BZ310LA_ C000001— and 1BZ310LA D000001—. It applies to 310L units built with any of three PowerTech 4.5 L diesel engine variants: 4045HBZ01, 4045TBZ01, and 4045HBZ02. Where procedures, wiring, or specifications differ between those engine models, the manual calls out the differences explicitly.

What this manual gives a working technician is the diagnostic layer on top of the repair layer. Instead of guessing, the 310L Backhoe Loader Operation & Test Technical Manual TM14156X19 supplies the DTC lookup and diagnostic routines, the operational checkout that verifies the machine before testing, the theory of operation that explains how each system is supposed to behave, the schematics and component locations needed to trace a fault, and the pressure, flow, resistance, temperature and torque values needed to confirm a repair. Sections are cross-referenced — a DTC entry will point you to the specific diagnostic group, and a diagnostic group will point you to the specific test port, wiring diagram, or adjustment procedure.

Coverage by System

The Engine section covers the 4045HBZ01, 4045TBZ01 and 4045HBZ02 engine variants in the context of the 310L machine — cooling package configuration, cold start aid (cold start advance on the mechanical engines and glow plug system on the 4045HBZ02), slow and fast idle adjustment, hand throttle linkage, and diagnostic checks for coolant temperature, oil pressure, air filter restriction, engine speed, thermostat opening, and intake manifold pressure. Cross-references lead into the component technical manuals (CTM104, CTM207, CTM320) for engine-internal detail.

The Electrical System section is the largest part of the manual. It documents the CAN bus (machine CAN, CAN termination resistors, JDLink gateway), engine control circuits for the 4045HBZ02 with its sensors, injectors, EGR and variable geometry turbo actuators, the engagement and monitor unit (EMU) with all of its inputs and outputs, the start and charge circuit, hydraulic system electrical circuits (pilot enable, pattern select, ride control, selective flow), transmission control circuits (FNR, gear select, clutch disconnect, MFWD, differential lock, backup alarm, park brake), and JDLink. Every harness has a component location drawing and a wiring diagram with circuit data tables.

The Power Train section covers the single-stage dual-phase torque converter, the transmission pump, the four-forward/two-reverse power shift transmission with its five clutch packs, the differential, the differential lock, mechanical front wheel drive (MFWD) and its self-applied limited slip differential, the park brake and the power boost service brake valve. Tests include stall speed, converter inlet pressure, system pressure, clutch pressures, cooler differential, and solenoid circuit leakage.

The Hydraulic System section covers the open-center hydraulic system, the fixed displacement single gear pump, the priority valve, the backhoe control valve with its inlet, swing, boom, bucket, crowd, auxiliary and extendable dipperstick sections, the pilot control system with pilot enable and pattern select (PEPS) manifold, the loader and stabilizer control valve, ride control, and the steering and brake circuit. Tests cover flow, system and circuit pressures, cylinder and valve leakage, drift, and pilot pressure and accumulator charge.

The Heating and Air Conditioning section covers the R134a system cycle, the compressor, condenser, receiver-dryer, expansion valve, evaporator, freeze control switch and high/low pressure switch, along with capacities, operational checks, leak testing and a full operating pressure diagnostic chart.

Who This Manual Is For

This 310L Backhoe Loader Operation & Test Technical Manual TM14156X19 is written for experienced technicians. It assumes access to the standard shop tooling plus the Deere-specific diagnostic equipment the procedures call out — Service ADVISOR, the JDG10273 Diagnostic Test Box, the JT02156A Digital Pressure and Temperature Analyzer, JT07148 Flowmeter, JT02161 and JT02162 transducers, flex probe kits and the various quick couplers and tee fittings listed per test. The diagnostic trouble code sections cover the complete DTC list for the ECU, EMU, TCU and VCU, each entry with alarm level, machine response, circuit information, component location references, diagnostic test box information, possible causes and cross-references to the diagnostic routines.

Because the manual covers three engine variants and multiple options (cab vs. canopy, manual vs. pilot controls, MFWD, ride control, selective flow, extendable dipperstick, JDLink), some menu tables, schematics and procedures contain items that will not apply to every machine. The manual identifies which items are option-dependent throughout.

Why Buy the Operation & Test Technical Manual TM14156X19

Diagnosing modern equipment without the correct manual costs time and parts. A 310L that throws a converter oil temperature warning, refuses to release the park brake, loses MFWD, chatters in the hydraulics, or will not hold a clutch pressure is expensive to troubleshoot by substitution. This manual replaces that with the actual test procedure, the specification value the reading must fall within, and the schematic or component location needed to isolate the fault correctly the first time.

Every procedure is written for the 310L specifically, not a generic backhoe. Torque converter stall speed is given for each of the three engine models. System pressure, cooler differential, pilot accumulator charge, brake boost pressure, clutch pressures and function drift all have their own target values. The wiring diagrams and hydraulic schematics are drawn for this machine’s harness set — cab harness (W14), canopy harness (W16), engine harness (W10), transmission harness (W13), fuel injector harness (W57), roof harness (W17), and the rest — with each harness given a component location drawing as well as a wiring diagram so a connector can be found on the machine, not just on paper.
