Part of the Yanmar Repair Manuals.
When a travel lever goes soft on an SV15 halfway through a trench, the machine will not tell you whether the fault is in the pilot valve, the control valve, or the travel motor itself. This 356 page Yanmar service manual for the SV15, SV17, and SV17(EX) mini excavators (2000 to 2005, powered by the 3TNV70-XBVA1 and 3TNV70-XBVA diesels) is where you find out, with measurement procedures, service standards, and disassembly steps for the hydraulic pump, control valve, pilot valve, swing motor, and travel motor.
It also carries the engine side of the job: compression measurement, valve clearance, injection timing, plus tightening torque lists and adjustment and repair coverage for the machine's electrical equipment, undercarriage, controls, and implement.
As a PDF download, it gets you from the table of contents to the exact section in seconds, instead of leaving a crew standing while you wait on a dealer counter.

Yanmar SV15, SV17, SV17(EX) Common Problems This Manual Covers
Weak, jerky, or fading hydraulic functions
Boom and arm response that turns spongy after warm-up usually points to aerated or low oil, a clogged filter, or wear inside the pump or valve stack. The Hydraulic Equipment section covers the hydraulic pump, control valve, and pilot valve for both the SV15 and SV17 so you can test and rebuild rather than guess.
Manual Section: Hydraulic Equipment p. 101Machine pulls to one side when traveling
Uneven travel or a noisy side is often a travel motor or travel circuit problem rather than the track itself. The Hydraulic Equipment section includes the travel motor for the SV15 and SV17 with the service detail needed to isolate the failing side.
Manual Section: Hydraulic Equipment p. 101Loose or thrown rubber tracks
Track tension drifts with wear, and a slack chain will walk off the idler on a turn. Undercarriage service, including rollers, idlers, and track components, sits in the Adjustment and Repair section along with the machine torque data for undercarriage hardware.
Manual Section: Adjustment and Repair p. 217Hard starting or low power under load
A tired 3TNV70 that cranks but will not pull usually needs compression measured and valve clearance and injection timing checked before anything gets replaced. The Engine section lays out those measurement, inspection, and adjustment procedures step by step.
Manual Section: Engine p. 57Hydraulic leaks at hoses and fittings
Seeping fittings and chafed hoses are the most common cause of a hydraulic tank that keeps losing oil. The General Cautions for Maintenance Work section covers correct hydraulic hose installation, hose specifications, seal handling, and air release of the hydraulic circuit after repairs.
Manual Section: General Cautions for Maintenance Work p. 9Electrical faults and sensor problems
Dead gauges, warning lights, and starting circuit gremlins waste more hours than most mechanical failures on a small excavator. The Adjustment and Repair section covers the machine's electric equipment so you can trace the circuit instead of swapping parts.
Manual Section: Adjustment and Repair p. 217Frequently Asked Questions
Which machines does this manual cover?
The Yanmar SV15, SV17, and SV17(EX) mini excavators from 2000 to 2005. It covers the 3TNV70-XBVA1 engine in the SV15 and the 3TNV70-XBVA engine in the SV17 and SV17(EX).
Does it include torque specs for undercarriage and implement bolts?
Yes. The Adjustment and Repair section lists machine tightening torques, including 78.4 to 98.1 N·m for track roller, sprocket, and travel motor bolts, and 44.1 to 58.8 N·m for M10 bolts such as bucket pin hardware. p. 217
Can I rebuild the hydraulic pump and travel motor with it?
Yes. The Hydraulic Equipment section covers the hydraulic pump, control valve, pilot valve, swing motor, and travel motor for the SV15 and SV17, with the service data needed for disassembly, inspection, and reassembly. p. 101
Does it give engine test values like compression pressure?
Yes. Standard compression is 3.2 MPa at 250 rpm and cold intake valve clearance is 0.2 mm, and the Engine section walks through measuring compression, adjusting valve clearance, and checking injection timing. p. 57
How quickly can I access this manual after buying?
Immediate download of the complete 356-page searchable Service Manual. Access it on any device, from a laptop at your desk to a phone in the field.
Am I able to print pages from this manual?
No restrictions at all. Print individual pages, full chapters, or the entire manual. The PDF is completely unlocked.
Is there a hydraulic diagram in this Yanmar SV15 Service Manual?
Full hydraulic system diagrams are included, covering circuits, valve locations, and hydraulic component specs for the Yanmar SV15, SV17, SV17(EX).
