Part of the Yanmar Repair Manuals.
Crack the drain plug on the water separator before the crew arrives and you already know whether this SV05 starts the day or sits through it. This Yanmar service manual, publication 0BKB2-G05000, takes the SV05-A and SV05-B mini excavators from daily checks all the way to full engine disassembly, covering the 2TE67-BV2 and 2TE67L-XBV3 diesels across 376 pages of factory procedure.
Inside are service standards for the engine, rubber crawler undercarriage, controls, and hydraulic cylinders, plus removal and reinstallation steps for the hydraulic pump, control valve, swing motor, and swivel joint. Wiring diagrams, monitor and alarm circuit descriptions, and a dedicated troubleshooting chapter back up the mechanical work.
Every hour the machine is down, someone is standing next to a trench waiting. This PDF puts the tightening torques, relief pressures, and wear limits in front of you so the repair is right the first time.

Yanmar SV05-A, SV05-B Common Problems This Manual Covers
Cranks but will not start
Water or contaminated fuel is the usual culprit on small diesel excavators, and it reaches the injection system fast. The Engine section covers the fuel oil injection system along with measurement, inspection, and corrective action for both the 2TE67-BV2 and 2TE67L-XBV3.
Manual Section: 4. Engine p. 69Weak, slow, or jerky hydraulic functions
Air in the circuit or a control valve problem shows up as a boom that hesitates under load. The Hydraulic System section explains control valve operation and lays out the full hydraulic oil circuit schematic so you can trace where the pressure is going.
Manual Section: 5. Hydraulic System p. 159Hydraulic leaks at hoses and fittings
Compact machines flex their hose routing constantly, and leaks tend to appear at fittings first. The opening section gives cautions for removal and installation of hydraulic equipment and piping, seal handling, and correct hose installation so the leak does not come back after reassembly.
Manual Section: 1. General Cautions for Maintenance Work p. 11Swing motor or swivel joint trouble
A swing that drifts or oil weeping from the center of the undercarriage points at the swing motor or swivel joint. The Hydraulic Equipment section walks through removal and reinstallation of the swing motor, swivel joint, hydraulic pump, and control valve.
Manual Section: 6. Hydraulic Equipment p. 191Starter, monitor, or alarm system faults
Intermittent electrical faults stop a machine as surely as a seized pin. The Adjustment and Repair section includes the electrical parts layout, wiring diagram, circuit descriptions for engine start, stop, and battery charge, and removal steps for the starter motor.
Manual Section: 7. Adjustment and Repair p. 263Rubber crawler wear and track problems
Lug wear and track condition decide whether the undercarriage climbs out of the trailer or spins. The Service Standards section gives rubber crawler specifications and wear limits, alongside machine performance figures and tightening torque lists for the whole machine.
Manual Section: 3. Service Standards p. 43Frequently Asked Questions
