Yanmar Excavator Parts Guide: Find the Right Part First Time
To order the right part for a Yanmar excavator or mini excavator, you need the complete model number, the serial number and the part reference from the parts catalogue for that machine. Yanmar itself says an engine or product can only be identified from the complete model and serial number. This guide shows how to gather those details, read a catalogue, deal with changed part numbers and buy genuine Yanmar parts for work in Portugal, Spain and the rest of Europe.
TL;DR
- Record the full model number and serial number from the machine plate before you look at any catalogue.
- Use the parts catalogue for your exact model, then match the part to its diagram and part number.
- If a number has changed or the catalogue shows options, confirm the current reference before ordering.
- Genuine Yanmar parts are made to match the original equipment specification, which is what keeps a repaired machine reliable.
- Send us the model, serial number and part reference at [email protected] if you want the match checked.

Start with the machine, not the part
Most wrong orders begin with a part described by its appearance: “the hydraulic filter”, “the track roller”. Yanmar builds a wide range of compact excavators, and the same component name can cover several different parts.
Before you search, write down:
- Model designation as shown on the machine plate (for example the ViO series name and suffix).
- Machine serial number, exactly as stamped.
- Engine model and engine serial number, if the part is an engine component. These are separate from the machine serial.
- Part reference or description, ideally from the old part, an earlier invoice or the service history.
- Photos of the plate and of the part, including any casting marks.
Keep the plate photo with your maintenance records. It saves a walk to the machine every time you need a filter or a seal.
Where the official catalogues and parts information sit
Yanmar publishes parts, service and operator manuals, but it does not sell service parts straight to end users. According to its parts FAQ, manuals and parts come through authorised distributors and dealers. That is why the catalogue is the common reference between you and any supplier.
For compact equipment in Europe, Yanmar’s genuine parts page points to its Y Parts portal. It lists categories including service kits, lubricants, pins and bushings, engine parts, seals and seal kits, undercarriage parts, bucket teeth and batteries.
Yanmar’s catalogues and documents page lists downloads for excavator models such as the SV08-1C, SV10, ViO12-2A, ViO17-1, ViO20-6/ViO23-6, ViO30-7/ViO35-7, ViO50-6B/ViO55-6B, ViO80-7 and SV86-7. Check there first whether your model has a current catalogue.
Older machines are common on European sites, and the catalogue for an older model may be a different edition from the one for a current machine. Use the edition that covers your serial number.
How to read a parts catalogue
A Yanmar parts catalogue is organised by assembly group, with exploded diagrams. Each diagram numbers its items, and a list beside it links each item number to a part number, a description and a quantity.
Work through it in this order:
- Confirm the catalogue covers your model and serial range. Catalogues state which machines they apply to.
- Find the assembly group. Engine, hydraulics, undercarriage, cab and attachments are separate sections.
- Locate the item in the diagram, then read across to the part number.
- Read the notes. Catalogues often flag parts that apply only to certain serial ranges, options or variants. One catalogue even warns that parts shown are not necessarily standard equipment on every machine, so treat the list as a reference and not a guarantee of fitment.
- Cross-check quantity. If the diagram shows two of an item and you need a pair, say so when you enquire.
A numerical index, where a catalogue has one, lets you work backwards from a number on an old part or invoice to the diagram it belongs to.
When the part number has changed
Parts are revised over a machine’s life. A number in an old invoice or an older catalogue edition may have been replaced by a newer one.
- Look for revision or supersession notes beside the item.
- Check whether the change applies from a certain machine serial number onward.
- If your number and the current catalogue disagree, do not guess. Give the supplier both numbers plus your serial number so the current reference can be confirmed.
- Do not mix up the machine serial with the engine serial when reading a note about an engine part.
Ordering an outdated reference usually means a delay, or a part that nearly fits and does not.
Genuine Yanmar parts and why fit matters
Yanmar states that its genuine parts are manufactured under ISO 9001 using the same materials, machinery and production methods as original equipment parts. For Europe, Yanmar advises choosing genuine parts to maximise performance, reliability, longevity and value because each part matches the original equipment specification.
For a working excavator, that matters in the places where small tolerances decide the outcome: seals and seal kits in hydraulic cylinders, pins and bushings in the boom and arm, filters protecting the engine and pump, and wear items on the undercarriage.
A practical rule: never describe or accept a compatible or aftermarket part as a genuine Yanmar part. If a part is not marked and supplied as genuine, treat it as something else, and decide knowingly.
Common parts people order for a Yanmar mini excavator
The table groups typical requests with the information you need to give. It does not replace the catalogue for your model.
| Part group | What to have ready | Why it matters |
|---|---|---|
| Service kits and filters | Model, serial number, engine model | Filter and kit contents differ by machine and engine |
| Seals and seal kits | Model, serial number, which cylinder or motor | Cylinders on the same machine can use different seals |
| Pins and bushings | Model, serial number, position (boom, arm, bucket) | Dimensions vary by position and variant |
| Engine parts | Engine model and engine serial number | Engine and machine serials are separate |
| Undercarriage parts | Model, serial number, track type | Track configuration varies |
| Bucket teeth and wear parts | Model, bucket width or type | Attachments differ between machines |
For engine-related parts, Yanmar engines also power other applications, so Iberparts’ range covers marine, agricultural, industrial and generator equipment alongside compact excavators.
Our perspective
Most parts problems we see are identification problems, not supply problems. A machine owner knows the part is worn, but the model suffix, the serial number or the engine reference is missing from the enquiry. We would rather spend five minutes confirming those details than see a machine wait for a second order.
We work with genuine Yanmar and Sensei parts, and we keep the focus on correct identification and compatibility. For contractors in Portugal and Spain, and across Europe, downtime costs more than the part. A catalogue check at the start is the cheapest way to protect a repair.
Keep your plate details, service history and old part numbers together. When you send them to us, we can help you find the right reference.

A safe approach to the repair itself
Parts identification is only half the job. Hydraulic systems hold pressure, and engines and fuel systems carry fire and injury risks. Follow Yanmar’s service manual for your model for removal, refitting and any specified settings, and use a qualified technician for hydraulic, fuel or electrical work you are not trained to do. Never take figures for torque or service intervals from a general guide; use the manufacturer’s documentation for your machine.
FAQ
What details do I need to find a Yanmar excavator part?
You need the complete model number and serial number, as Yanmar states that identification depends on both. For engine parts, add the engine model and engine serial number. A photo of the machine plate and the old part helps.
Where can I find a parts catalogue for my Yanmar mini excavator?
Yanmar publishes catalogues and documents for many compact excavator models on its support catalogue page. Its parts FAQ also says manuals are available through authorised distributors and dealers. If your model is not listed, ask your supplier to check the catalogue edition for your serial number.
What do I do if my part number is no longer valid?
Give your supplier the old number, the machine serial number and, if possible, the part description or a photo. They can confirm whether a newer reference applies. Do not order a near match by guesswork.
Are aftermarket parts the same as genuine Yanmar parts?
No. Genuine Yanmar parts are made by or for Yanmar to its own standards, and aftermarket or compatible parts are a different category. At Iberparts we only describe genuine Yanmar and Sensei parts as genuine.
