Part of the Yanmar Parts Manuals.
An alternator that stops charging on a ViO70 is a one-hour swap if the part in the box matches the machine, and a lost day plus a restocking fee if it does not. This parts catalog settles that question before you order: it is Yanmar publication 000Y00S3631 for the ViO70 excavator with the 4TNE98-BV engine, covering machines from serial number 00711 onward.
Across 164 pages it identifies the parts behind the main assemblies, from the fuel tank and fuel lines to the radiator and mount, engine mounts, accelerator, and battery, plus a wiring diagram covering the starting switch, fuel meter, horn, wiper motor, and alternator circuits. Interchangeability marks and effective machine numbers tell you which part fits your serial range.
Download the PDF, find the reference number, and order once. The machine goes back to work; the guesswork does not.

Yanmar ViO70 Common Problems This Manual Covers
Slow cranking or no start
A ViO70 that clicks or cranks slowly usually traces back to the battery, its cables, or corroded terminals. The Battery section lists the replacement battery and its mounting hardware for this serial range so the unit you order actually fits the tray.
Manual Section: Battery p. 8Dead gauges, horn, or wipers
A fuel meter that reads empty, a silent horn, or a wiper that quits mid-shift is faster to chase with the circuit in front of you. The Wiring Diagram section covers the wiper motor, heater switch, horn switch, fuel meter, starting switch, and alternator.
Manual Section: Wiring Diagram p. 3Overheating and coolant leaks
Leaking or clogged radiators show up on the walkaround before they show up on the temperature gauge. The Radiator & Mount section identifies the radiator, its mounting parts, and related hardware so you can replace what is weeping instead of topping up all season.
Manual Section: Radiator & Mount p. 6Water or debris in the fuel
Contaminated diesel and cracked fuel lines starve the 4TNE98-BV and leave the crew waiting on a machine that stumbles under load. The Fuel Tank & Fuel Line section lists the tank, lines, and fittings so you can renew the whole run instead of patching one leak.
Manual Section: Fuel Tank & Fuel Line p. 7Engine vibration from worn mounts
Perished rubber engine mounts let vibration hammer through the frame and shake other components loose over time. The Engine Mount section identifies each mount and its hardware so you replace them as a set with the correct parts.
Manual Section: Engine Mount p. 5Sticking or erratic throttle
A throttle that hangs or will not hold rpm makes fine grading work miserable and is often worn linkage rather than an engine fault. The Accelerator section breaks out the throttle components so you can spot and order the worn piece.
Manual Section: Accelerator p. 4Frequently Asked Questions
Which machines does this parts catalog cover?
It covers the Yanmar ViO70 excavator fitted with the 4TNE98-BV engine, from machine serial number 00711 onward. The publication number is 000Y00S3631, so you can match it against the plate on your machine before buying.
Is this a service manual with repair procedures?
No. This is the parts catalog: part listings and reference numbers for identifying and ordering components, not teardown procedures or torque specifications. It pairs well with a service manual, but its job is making sure the part that arrives is the part that fits.
How do I confirm a part fits my serial number?
Each listing carries an effective machine number plus interchangeability and change marks. The How to Read This Parts Catalog section explains the reference numbers, levels, and remarks marks so you can confirm fitment for your serial range before spending money. p. 2
Does it include an electrical wiring diagram?
Yes. The Wiring Diagram section covers the wiper motor, heater switch, horn switch, fuel meter, starting switch, and alternator, which makes it the starting point when a circuit or gauge goes dead on the machine. p. 3
