Yanmar B95W Common Problems This Manual Covers
Yanmar B95W hydraulic pump sluggish, boom and arm move slowly or stall under load p. 636
Check pilot pressure at the working pump test port; spec is 30 bar (page 52). If pressure is low, verify hydraulic oil level, then inspect the working pump relief valve setting. Cross-reference the A10VO pump troubleshooting chart on page 636 for no-swing-out conditions and sluggish movement. Replace the hydraulic return filter if the service interval has passed.
Manual Section: Hydraulic Pump (A10VO DFLR/DFSR) TroubleshootingEngine cranks but won't fire, or starts and stalls within seconds of ignition p. 120
Replace the fuel pre-filter insert and torque the housing to 17-18 Nm (page 120), then bleed the fuel system per the Tcd 3.6 L04 procedure. Inspect fuel supply lines for air ingestion at the suction side. Verify battery spec: 12 V / 135 Ah (page 50). Pull stored ACTIA fault codes before condemning sensors or ECU.
Manual Section: Diesel Engine FaultsBoom drifts down under load after controls are released, cylinder won't hold position p. 59
Measure cylinder drift against the 3.5 mm/min allowable maximum in Technical Data (page 59). If over spec, remove the load-holding valve and inspect for seat wear or contamination before pulling the cylinder. Main system pressure is 300 bar (page 53); confirm the circuit reaches spec before condemning internal seals. Troubleshooting procedures are in Setting Instructions on page 636.
Manual Section: Technical DataWarning buzzer activates and display shows fault codes, machine reduces power without obvious cause
Connect the ACTIA diagnostic tool and read all active DTCs. Check battery condition first: spec is 12 V / 135 Ah / 1000 A (page 50); a weak battery produces cascading sensor faults and false warnings. Inspect all ground connections at the engine block and frame, clean and re-torque before replacing any sensor or module.
Manual Section: Electrical System Fault Indications and Warning BuzzerDPF regeneration fails or is blocked, engine power reduction active, ash warning on display p. 791
Check the DPF ash load on the keypad display. If ash load is critical, replace the filter per the procedure on page 791. Verify the SCR-feed pump filter cartridge is within its 3-year replacement interval (page 115). For stalled regeneration, confirm coolant is at operating temperature before forcing a regen cycle; never park near flammable material during active regeneration.
Manual Section: Diesel Particle Filter (DPF) Regeneration IssuesMachine loses travel drive or pulls hard to one side on grades under load p. 636
Measure travel pump high pressure at the test port; spec is 480 bar (page 51). If one side reads low, check the travel motor case drain and brake release valve before pulling hardware. On wheeled excavators, also inspect axle and wheel bearings: steering pull combined with low travel pressure often traces to the driveline. Motor and valve isolation steps are in Setting Instructions, page 636.
Manual Section: Setting InstructionsFrequently Asked Questions
How to reset Yanmar B95W error codes
For some errors, rectification and cycling the ignition (off for 30 seconds, then on) may clear the diagnostics lamp. For specific issues like resetting the diesel particle filter's soot and ash content, a service tool (SERDIA) is required. The manual also mentions diagnostic tools like the "Diagnostics control unit with USB connection cable (CAN Interface – PASSTHRU + XS2G), spare part number: 5 322 000 111" and a "Machine diagnostics connection cable, length: 8 meters, spare part number: 6 407 310 021" for more comprehensive error management.
What are the replacement specifications for hydraulic filters?
The manual specifies replacing the "insert of hydraulic oil return filter" according to the maintenance indicator (page 745). No specific replacement procedure or part number is provided for this hydraulic filter. However, for the "lubricating oil filter" (engine oil filter), the procedure involves using tool order no.: 0189 9142, oiling the seal, and tightening to 10 Nm - 12 Nm (page 117).
What are the replacement specifications for fuel filters?
The manual specifies replacing the fuel filter and fuel pre-filter. For the fuel change filter, loosen and unscrew with tool (order no.: 0189 9142), oil the seal of the new DEUTZ original spare filter, and tighten to 10 Nm - 12 Nm. For the fuel pre-filter insert, the tightening torque is 17 Nm - 18 Nm.
How do you fix yanmar B95W hydraulic pump sluggish, boom and arm move slowly or stall under load?
Check pilot pressure at the working pump test port; spec is 30 bar (page 52). If pressure is low, verify hydraulic oil level, then inspect the working pump relief valve setting. Cross-reference the A10VO pump troubleshooting chart on page 636 for no-swing-out conditions and sluggish movement. Replace the hydraulic return filter if the service interval has passed.
How quickly can I access this manual after buying?
Instant PDF download. You get the full 913-page searchable Service Manual immediately after payment. Open it on your laptop, tablet, or phone right in the shop.
