Yanmar SV100-2A Common Problems This Manual Covers
Yanmar SV100-2A hydraulic pump weak output, machine requires high RPM before implements or tracks respond
Check system relief pressure at the pump outlet against the spec of 3989 PSI (27.5 MPa) at 7.9 GPM (30 L/min) on page 75. Inspect pump for abnormal noise, low flow, and overloading symptoms covered. If pressure reads low under load, pull the pump and inspect for worn internals before condemning the relief valve. Verify hydraulic oil level is at 15.8 Gals. (60 L) capacity on page 39.
Manual Section: Hydraulic Pump TroubleshootingEngine won't reach rated power or stalls under load, sluggish digging response across all implements
Measure cylinder compression and compare against 479 PSI (3.3 MPa) at 250 rpm from page 29. Check air cleaner element condition; a clogged filter on an element with 20.8 sq.ft. (1.93 sq.m) filtration area starves the engine fast. Inspect fuel filter (310 sq.in. filtration area) and engine oil at 11.8 Qts. (11.2 L) capacity per page 39. If compression is low, follow engine failure diagnosis procedures starting.
Manual Section: Engine Failure DiagnosisTravel drive inconsistent, one or both tracks slip or fail to move under normal load
Inspect the travel motor for insufficient torque, abnormal sounds, and delay in start/stop per . Verify system relief pressure holds at 3989 PSI (27.5 MPa) under travel load before pulling the motor. Check rubber crawler wear dimension against the 1.30 in. (33 mm) standard on page 62; worn tracks increase slip and mask motor faults. Confirm track tension and undercarriage service standards on page 53.
Manual Section: Travel Motor TroubleshootingControl valve spool sticking, bucket or arm movement jerky or stops mid-cycle
Remove and visually inspect spool condition per the control valve troubleshooting procedures. Clean spool bores and check for scoring, contamination, or debris causing load-side issues. Verify pilot pressure is reaching the valve by checking pilot unit operation. Hydraulic oil contamination is the most common cause; flush and refill to 15.8 Gals. (60 L) with correct grade per page 39 if metal particles are found in the old oil.
Manual Section: Control Valve TroubleshootingElectrical fault codes displayed, machine derated or certain functions locked out
Pull active error codes and cross-reference the corrective measures table starting. Note the exact code number before clearing, since some codes point to Engine ECU faults and others to the Hydraulic ECU. Inspect wiring harness connectors at the controller for corrosion or loose pins before replacing sensors. Refer to the wiring diagram on page 697 to trace circuit paths back to the affected sensor or actuator.
Manual Section: Electric System Error Code DiagnosisSwing rotation slow, stops short of rated speed, or makes abnormal noise during rotation
Measure swing speed against the spec of 9.1 rpm and check swing motor displacement at 2.35 cu.in./rev (38.5 cu.cm/rev) from page 27. Inspect the motor for insufficient torque, abnormal heating, and oil leaks per . Verify swing bearing condition and torque specifications on page 53; a worn bearing increases drag and mimics low motor output. Check system relief at 3989 PSI (27.5 MPa) on page 75 to rule out a pressure-side cause before pulling the swing motor.
Manual Section: Swing Motor TroubleshootingFrequently Asked Questions
How do you reset the YANMAR SV100-2A hydraulic/monitor error code?

What does error code mean on a YANMAR SV100-2A excavator?
On the YANMAR SV100-2A excavator, an error code displayed on the LCD monitor indicates an abnormality detected by the engine ECU or other controllers. These codes correspond to specific malfunctions within the machine's electrical or hydraulic systems.
What are the torque specs for YANMAR SV100-2A track motor or final drive bolts?
For the YANMAR SV100-2A, the tightening torque for track motor mounting bolts (M16) is 195.3 to 224.2 ft·lbf (264.8 to 304 N·m). For track motor mounting stud bolts and nuts (M16), the torque is 123.2 to 151.9 ft·lbf (167 to 206 N·m).
What are the torque specs for YANMAR SV100-2A swing bearing bolts?
For the YANMAR SV100-2A, the tightening torque for swing bearing installation bolts is 224.1 to 238.6 ft·lbf (303.9 to 323.5 N·m). This applies to both the turning frame to outer race (M16 × 85) and the track frame to inner race (M16 × 90) bolts.
