All 928 pages of this Yanmar SV85 2PB Service Manual zero in on one machine: your compact excavator, covered from diesel engine internals to full vehicle electrics. Inside, you get complete hydraulic schematics covering monobloc, articulated, and circular boom configurations, plus an extensive wiring section spanning two serial-number ranges (TC08540102 through TC08540178, and TC08540179 onward) so you're working from the correct revision for your machine. Diagnoses and error codes, calibration procedures, setting instructions for the Control Valve SX14 and DPX100/5, connector pinouts, and a full troubleshooting section round out the technical content. Torque the M18x2 piston nut to 200 Nm; for the hydraulic cylinder Ø35/45 guide bushing (M50x2 thread), stay between 200 and 230 Nm. Your excavator is down and every hour counts. One-click download, search any spec by keyword, jump straight to the section you need.

Yanmar SV85 2PB Common Problems This Manual Covers
Yanmar SV85 2PB hydraulic pump grinding noise after high hours, boom won't lift at full speed
Measure working hydraulic pressure at the test port; system pressure should hold 300+10 bar at the main relief valve (page 52). If pressure reads low, inspect the suction line for air ingress or restriction, check hydraulic fluid level, and verify the pump control valve spool moves freely. Replace hydraulic fluid if contamination is suspected.
Manual Section: Hydraulic Pump Troubleshooting (A10 VO DFLR/DFSR)Engine coolant warning lamp on, temperature gauge climbing toward the red zone p. 58
Check coolant level first; the engine holds 3.5 l (page 130). Clean debris from the radiator grille thoroughly, then inspect all cooling hoses for cracks or swelling. If the warning persists after topping up, consult the fault and remedy tables on page 58 to identify whether the thermostat, water pump, or a blocked passage is the root cause.
Manual Section: Engine Faults and Remedies (General)Engine cranks but won't fire, or stumbles and loses power under load p. 103
Drain the water separator bowl immediately if the warning lamp or horn activates (page 103). Replace the fuel filter cartridge at every oil change and torque the new cartridge to 10-12 Nm (page 107). If the engine still runs rough after servicing the fuel system, check for air ingress at suction-side fittings before moving on to injection pressure testing.
Manual Section: Engine Faults and Remedies (General)Track derails or runs with excessive slack and vibration during travel p. 774
Inspect track shoe condition and check mounting security at every 100-hour and 500-hour service interval (page 774). Verify bottom and top rollers spin freely with no binding or heat. Adjust track tension if sag exceeds spec. A roller that drags or runs hot should be pulled before the next work shift, not deferred to the scheduled service.
Manual Section: MaintenanceHydraulic oil seeping from hose fittings or connections after recent service p. 829
Torque DKO hose fittings (L6 M12x1.5) to 18 Nm on first assembly (page 840). Both under-tightening and over-tightening are primary leak sources; review the fitting procedure on page 829. Install a new sealing ring each time you break a hydraulic connection (page 831), and confirm the hose sits without twist before final torque.
Manual Section: Fitting Hydraulic Screw Connections (Repair)Display warning lamp on, cab indicator showing filter, pressure, or charge fault
Identify which indicator is active: hydraulic oil filter, engine oil pressure, coolant temperature, and battery charge each have a dedicated display symbol in the Electrics section. Check the relevant fluid level or filter condition first. If a battery charge warning persists, verify the battery is 12 V / 100 Ah / 900 A (page 50) and load-test before replacing the alternator.
Manual Section: Display Fault Indication (Electrics)Frequently Asked Questions
How do I reset the service light on a YANMAR SV85 2PB?
To reset the service light, which is referred to as the "daily running hours counter" in the manual, press the "OK" button to activate the icon and reset it. After confirmation through the MCU, the icon will become inactive once again.
What does the error code mean on a YANMAR SV85 2PB?
The manual refers to the "DEUTZ Trouble Code List EMR4_DE_EN.pdf" for error code meanings. This list provides DTC codes, SPN-Values, Failure types, Function/Modules, Numbers, and Descriptions. For example, DTC Code 622A01 (C communication) with SPN-Value 207361 means "FMI=2—DATA ERRATIC, INTERMITTENT OR INCORRECT" for the HMI, indicating "No communication to the HMI (Display or dashboard)".
How to reset monitor on YANMAR SV85 2PB
The manual describes how to reset the "daily running hours counter" by pressing the "OK" button to activate the icon and reset it on page 813. Other monitor settings like units, language, time, date, brightness, and immobilizer activation time can be adjusted individually as described on pages 805-813.
What are the replacement specifications for Hydraulic hoses?
Hydraulic hoses must be replaced if damage to the outer layer reaches the intermediate layer, if there are embrittled patches, deformations, leaks, or damage to hose fittings or connections. Only manufacturer-specified hoses may be used, and they must be routed and mounted by expert staff.
How quickly can I access this manual after buying?
You get a 928-page searchable PDF that downloads instantly after checkout. Open it on your laptop, tablet, or phone, and bring it right to the shop floor.
Can I print this manual?
Yes, print as many copies as you want, and there are no restrictions. Many mechanics print the section they need and bring it to the shop floor.
Are electrical wiring diagrams included in this Yanmar SV85 2PB Service Manual?
Yes. You'll find full electrical schematics with wire routing diagrams, connector identification, and circuit descriptions.
