Part of the Yanmar Repair Manuals.
Before you touch the main relief valve on an SV85, you want the factory setting in front of you: 300+10 bar on the 6SX14 control valve, plus the measuring connections to prove it. This Yanmar SV85 2PB service manual (serial prefix TC0854) puts those numbers on the bench, from cylinder drift limits to piston nut torques, so a pressure complaint costs you a test port reading instead of a teardown on a hunch.
Across 928 pages it covers the Deutz TCD 2.9 L4 engine in full, working hydraulics and travel drive, setting instructions for the SX14 and DPX100/5 control valves, wiring for both serial ranges, the maintenance inspection plan, and diesel particle filter replacement.
The PDF carries 333 bookmarks and prints cleanly, so the pages you need can go to the bench and get dirty while the machine is open.

Yanmar SV85 2PB Common Problems This Manual Covers
Hard starting and water in the fuel
When the water trap warning lamp or horn triggers, the bowl must be emptied immediately, and ignoring it leads to rough running and lost power. The Diesel Engine section covers draining the separator and replacing the fuel filter cartridge, torqued to 10-12 Nm, at every oil change.
Manual Section: Diesel Engine p. 59Boom or dipperstick drifts down
A load that creeps toward the ground means leaking cylinder seals or valve spool wear, and guessing which means pulling the wrong component. The Technical Data section gives the permissible drift values, 3.5 mm/min for the monobloc boom and 5.5 mm/min for the dipperstick, so you can measure before you tear down.
Manual Section: Technical Data p. 47Slow, weak hydraulic functions
Sluggish boom, arm, or travel response usually traces back to relief pressures that have wandered off spec. The Setting Instructions section gives the adjustment procedures for the SX14 and DPX100/5 control valves and the travel drive, with the main relief at 300+10 bar and the LS relief at 280+10 bar.
Manual Section: Setting Instructions p. 511Display, switch, or wiring faults
Chasing an electrical fault with the wrong diagram wastes a day. The Electrics section carries two complete vehicle wiring projects, V0.1.3 for serial numbers TC08540102 to TC08540178 and V0.1.6 from TC08540179 onward, so match your serial number before you start probing.
Manual Section: Electrics p. 587Track slack and undercarriage wear
Loose chains and rough-running rollers turn into derailments and chewed sprockets. The Maintenance inspection plan schedules checks of track shoe condition and mounting and of bottom and top roller running at the 100 and 500 operating hour intervals.
Manual Section: Maintenance p. 767DPF warnings and regeneration trouble
A blocked diesel particle filter on the Deutz TCD 2.9 L4 shows up as warnings and lost power. The Options section covers the exhaust gas after-treatment system, including DPF replacement, alongside the auto-idling system.
Manual Section: Options p. 815Leaks at hydraulic fittings
Overtightened or badly seated DKO taper couplings weep no matter how many times you crank on them. The Repair Instructions section covers pipe connection technology and the correct fitting and tightening of hydraulic screw connections.
