Yanmar B08-3, B12 2006 Parts Catalog

If you’ve spent money on a part that didn’t fit because the aftermarket catalog listed the wrong application, you’re not alone. The Yanmar B08-3, B12 2006 Parts Catalog ends that loop. It gives you the factory part numbers straight from the Yanmar consumables listing. No cross-reference guesswork. No returning filters.

Two excavator models: B08-3 and B12.

Page 2 lists the B08-3 fan belt, radiator cap, air element, fuel element, engine oil element, and hydraulic return and suction elements. Page 3 covers the B12 with its own set of filter elements. You get the Yanmar part number, description, and quantity per machine. That’s all you need to order correctly.

Yanmar B08-3, B12 2006 Parts Catalog: What’s Inside

This is not a service manual. There are no torque specs, no overhaul procedures. What it does contain is a clean, model-specific breakdown of every filter, belt, hose, and seal the factory expects you to replace on schedule. The catalog is organized by model – excavators, loaders, carriers. For the B08-3 and B12, you’ll find the exact consumables as listed by BT Equipment, the authorized distributor, as of February 2006.

B08-3 Excavator Consumables Page 2

Turn to page 2 and you see the parts list for the B08-3: Belt Fan (12943042280), Cap Radiator (17244613450), Element Air (11965512560), Element Engine Fuel (11981055650), Element Engine Oil (11930535150), and several hydraulic filtration components. Each line shows quantity required per machine. If you need a hydraulic return element, the part number is 17244673700. The bottom radiator hose is 17244713610; top hose is 17244713600. Having these numbers printed in front of you means you hand the parts counter a Yanmar number, not a guess.

B12 Excavator Part Numbers Page 3

Page 3 covers the B12. The B12 uses a different air element (17102212530) and a different fuel element (12455055700) compared to the B08-3. Oil element is 11966035150; hydraulic return element is 17214173760; hydraulic suction element is 17213773700. Notice the subtle differences – ordering a B08-3 air filter for a B12 will leave you with a part that doesn’t fit. The catalog prevents that.

Does the Catalog Cover Seal Kits and Undercarriage?

Yes, for many models in the same document. While the B08-3 and B12 pages focus on basic consumables, the full catalog includes seal kits and undercarriage sections for models like the VIO20-3, VIO35-2, and VIO50-3. If you work on multiple Yanmar machines, this single 64-page file gives you the numbers for track adjuster seals, hydraulic cylinder seals, and undercarriage components. Keep it in your tablet or print the relevant pages for the machine on your lift.

OEM Part Numbers vs. Aftermarket Cross-References

Aftermarket catalogs often group multiple models under one part number to reduce inventory. That leads to mismatched micron ratings, thread sizes, or belt lengths. The Yanmar factory catalog lists each part by its original engineering number. If the B08-3 uses 11965512560 for the air element, that is the only number that guarantees the correct filter media and sealing surface. Use an aftermarket cross-reference at your own risk – I’ve seen it cost a shop a blown hydraulic system because the bypass valve setting was wrong. I’ve personally seen a shop order a hydraulic return filter from an aftermarket catalog using a cross-reference that was off by one thread pitch. The filter seated but the bypass didn’t open at the correct pressure, leading to a pump cavitation issue. That’s a $3,000 mistake because someone saved $2 on the filter. The factory part number eliminates that variable.

For context on why OEM documentation matters across the Automotive Industry Overview trust authentic specifications over generic listings. The same principle applies to compact excavator maintenance.

If you maintain a B08-3 or B12, you might also find these related catalogs useful:

• Yanmar B08-3 Crawler Back-hoe Parts Catalog 2004

In the wider Automotive Industry Overview, parts catalogs like this one are the baseline for any repair that starts with “get the right part.” Without the factory number, you’re gambling.

Get the Right Part the First Time

This catalog lives on your device – no physical paper to get greasy, but print it if you want. The format is PDF, searchable by model and part number. 64 pages, published 2006, by Yanmar via BT Equipment. Access the Factory Manual and stop wondering if the filter you ordered will thread on correctly.

Does this catalog include torque specs for the B08-3?

No. This is a parts catalog, not a service manual. It lists part numbers only.

How do I know which filter element fits my B12?

Cross-reference the part numbers on page 3 of this catalog. The listing shows the Element Engine Fuel (12455055700), Element Air (17102212530), Element Oil (11966035150), and others. Each part is listed with the quantity per machine. If you have the old part, compare the stamped number to the chart. If you don’t have the old part, you can verify by the model year – this catalog covers 2006 production. Never use a generic cross-reference from a parts store; they often mismatch the thread pitch or micron rating. Stick to the Yanmar number.
