All 745 pages of this Yanmar SV100-2A 2PB Service Manual are built around one machine: the 2015-2018 excavator, from engine internals to hydraulic circuit operation. Inside, you get complete wiring diagrams covering every circuit from engine ECU start/stop logic to the hydraulic controller, plus full hydraulic schematics tracing pump, control valve, swing motor, and travel motor fluid paths. The troubleshooting chapter includes a quick-reference fault table and a full error code library, while the service standards section delivers torque tables, pressure adjustment specs, and exploded views for every major assembly. Engine mount vibroisolating rubber torques to 264.8-304 N•m; the hydraulic pump M5 socket head bolts tighten to 6.9 N•m. Every hour your machine sits costs money. Download this PDF, pull it up on your phone or tablet right at the machine, and let the bookmarks take you to the exact spec in seconds.

Yanmar SV100-2A (2PB) Common Problems This Manual Covers
Yanmar SV100-2A hydraulic pump weak or slow, machine only responds at high RPM
Check system relief pressure against the spec on page 76: piston pump P1 and P2 circuits must hold 3989 PSI (27.5 MPa) at 7.9 GPM. Inspect the pump for abnormal noise or flow loss per the Hydraulic Pump Troubleshooting procedures. Compare actual discharge against the rated 2.26 cu.in./rev listed on page 27 before condemning the unit.
Manual Section: Hydraulic Pump TroubleshootingSwing, travel, or implement force drops noticeably under load, machine feels sluggish
Inspect the control valve for spool stroke and attachment speed irregularities per the Control Valve Troubleshooting procedures. Cross-reference the Quick Reference Table starting page 732 to isolate whether the fault is implement force, speed, or drift. Verify system pressure has not dropped below 3989 PSI (27.5 MPa) at the P1/P2 circuits on page 76 before pulling components.
Manual Section: Control Valve TroubleshootingEngine turns over slowly, stalls under load, or cranks without firing at all
Replace the engine oil filter at its 500-hour or annual interval per page 37. Inspect the air cleaner element: allowable intake restriction maxes out at 0.90 psi (6.23 kPa) per page 92. Run compression inspection per the Engine Failure Diagnosis procedures in the Engine section starting page 82 to confirm cylinder condition before chasing fuel or electrical faults.
Manual Section: Engine Failure DiagnosisCoolant temperature warning triggers during normal work, gauge climbs into alarm range p. 174
Clean radiator fins thoroughly before suspecting deeper faults; packed fins block airflow faster than any other failure mode. Pressure-test the cap: relief valve must open between 10.8 and 14.8 psi (75-105 kPa) per page 174. If coolant temperature still reaches the alarm threshold of 224.6-235.4°F (107-113°C), work through the Cooling System procedures in the Engine section starting page 82.
Manual Section: EngineTravel motor meanders or speed won't switch to high, one track slower than other
Inspect the travel motor for 2-speed switching faults and pressure buildup issues per the Travel Motor Troubleshooting procedures. Check for leakage at the floating seal and case drain. Measure working pressure against the P1/P2 relief spec of 3989 PSI (27.5 MPa) on page 76 to confirm whether the fault is inside the motor or upstream in the valve circuit.
Manual Section: Travel Motor TroubleshootingFrequently Asked Questions
How do I manage DPF regeneration intervals on a Yanmar SV100-2A?
DPF service intervals on the SV100-2A are managed through the ECU or via the SMARTASSIST DIRECT (SA-D) tool. When the DPF alarm lamp illuminates, initiate stationary regeneration through SA-D by selecting the regeneration function. Without a DPF alarm, clean the DPF every 3000 hours of operation. Regeneration requires connecting the SA-D tool to the engine wire harness and following the on-screen prompts for stationary regeneration.
How do I clear fault codes on a Yanmar SV100-2A?
To clear error information for EGR errors, connect the SMARTASSIST DIRECT (SA-D) tool to the engine wire harness. Select Diagnostic Codes and Defect History from the SA-D menu, then press the All Clear button. This clears the error information from the defect history.
What do the error codes mean on a Yanmar SV100-2A?
The error codes and their meanings for the Yanmar SV100-2A are listed in the Error Code List table. This table provides the error code, classification, error description, detection condition, causes, and corrective measures for each fault.
What is the hydraulic oil pressure spec for a Yanmar SV100-2A?
The system relief set pressure for Piston pump P1 and P2 is 3989 PSI (27.5 MPa), and for Gear pump P3 it is 3510 PSI (24.2 MPa). The circuit relief set pressure for most components including Boom, Arm, and Bucket is 4496 PSI (31 MPa), while for Blade at rod end it is 2176 PSI (15 MPa).
How quickly can I access this manual after buying?
