Yanmar B22-2, B22-2 C, B22-2 CR, B22-2 P, B22-2 PR 1996 Parts Catalog – Get the Right Part the First Time

If you’ve ever ordered a part for a Yanmar B22-2 or any of its variants – the B22-2 C, B22-2 CR, B22-2 P, or B22-2 PR – and got a box that didn’t fit, you know the pain. Aftermarket catalogs guess at supersessions, drop dimensions, and skip the paint codes. This Parts Catalog from Yanmar’s last European edition (1996) fixes that. 147 pages of factory-verified illustrations, part numbers, and color specifications. No guesswork on which seal fits the 3TN75L-RB1 engine or which bucket cylinder matches your machine’s serial number range. I’ve torqued bolts on these crawler backhoes for 28 years; having the OEM parts breakdown saves hours of cross-referencing and return trips to the dealer. This is the same book a Yanmar dealer uses – not a reprint, not a compressed PDF.

Picturesque Index: Visual Parts Identification

Flipping through the manual you’ll hit the “PICTURESQUE INDEX(1) MAIN PARTS” and “PICTURESQUE INDEX(2) HYDRAULIC SECTION”. These aren’t generic line drawings – they’re exploded views keyed to the part number tables. The index is broken into Figure 01-12, 13-24, 25-36, 37-48, 49-60, and 61-63, each covering a specific subsystem. Need the hydraulic pump seal kit? Go to the hydraulic section figures. The track frame components? Check the chassis figures. Every callout matches a numbered list with the Yanmar genuine part number. No searching third-party sites; the factory layout is logical and repeats the same scale and orientation across all figures. Use them to verify the shape of the bracket or the orientation of the valve body before you order.

Specifications: Engine and Dimensions

Page 2 of the catalog lists the full specs for the B22-2 P[R] and B22-2 C[R] models. Engine is the 3TN75L-RB1 – vertical 3-cylinder water-cooled diesel. Transport length 4120 mm, width varies from 1400 mm (P) to 1445 mm (C), height 2340 mm (P) or 2390 mm (C). Standard bucket capacity 0.06 m³ (0.10 m³ old). Max digging depth 2360 mm (blade down 2500 mm). Travel speed 2.3 km/h (rubber crawler 2.4 km/h). Machine mass from 2200 kg to 2350 kg depending on model. These numbers matter when you’re ordering undercarriage parts: the longer rubber crawler option requires different sprockets and idlers. The table also lists track shoe width (std. 270 mm, optional 300 mm). Don’t trust a catalog that doesn’t break out the rubber vs. steel crawler specs.

Table of Painted Color: Matching Paint Codes

Page 3 has a full “TABLE OF PAINTED COLOR” with Munsell numbers and Yanmar part numbers for touch‑up paint. If your B22-2 C has faded yellow or the grayish green on the boom, you can match it exactly. The colors: Yanmar New Permanent Yellow (5.2Y8.5/11), Yanmar New Deep Green (0.6B2.2/4.2), Yanmar Grayish Green (2.9BG4.8/3.0), Yanmar Dark Olive Gray, and Yanmar Charcoal Gray (N2). Each lists the 16L can and spray can part numbers. I’ve seen guys try to match with hardware‑store rattle cans – the green never matches the OEM decals. Use the factory paint code from this catalog and save the repaint headache.

Preface Notes: What This Catalog Is and Isn’t

The preface on page 1 clearly states: “This parts catalog is not a technical data manual setting forth servicing procedures.” It’s a Parts Catalog – exploded diagrams and part numbers only. If you need torque specs or adjustment procedures, you need the service manual. But if you’re rebuilding the hydraulic system or replacing undercarriage components, this catalog is the only way to get the correct Yanmar genuine part number without the dealer having to decode your machine serial. The preface also warns: “Be careful not to use the simple parts available in the market; otherwise their use in repairing causes such as an early breakage.” That’s straight from Yanmar – cheap aftermarket seals fail, cheap bearings wear out. Use this catalog to order genuine parts.

Model Codes and Serial Numbers: Identifying Your Machine

The preface lists model codes: B22-2 C‑EP (172171ク), B22-2 CR‑EP (172171ク), B22-2 P‑EP (172171キ), B22-2 PR‑EP (172171カ), and the option model 172174E. Serial ranges for vehicles: 30501~31409 (built 92/8 to 94/11). Engine serial range for 3TN75L-RB1: 44461~48831 (92/6 to 94/11). Before ordering any part, match your machine number to these ranges. A part superseded after serial 31409 won’t fit an earlier machine. This catalog covers the last edition (Jan. 1996), superseding the Dec. 1992 first edition. If you own a later machine, you’ll need a newer manual – but for the majority of B22-2s sold in North America and Europe through the mid‑90s, this is the definitive parts reference.

Who Needs This Catalog

This is for anyone owning or working on a B22-2 series Yanmar crawler backhoe. DIY owners doing their own repairs – you’ll save the markup from dealer parts lookup fees. Professional mechanics billing by the hour – you can’t afford to order the wrong hydraulic fitting and wait for a return. Equipment dealers stocking parts – use the illustrated index to quickly locate components on the shelf. Even if you’re not a Yanmar specialist, the exploded views are clear enough to walk you through disassembly. Pair it with the Yanmar B22-2 1995 Parts Catalog if you need cross-reference to earlier serial ranges, or the Ammann Yanmar B12 B17 Parts Catalog for smaller Yanmar backhoes. For larger models, see the Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs.

Source Validity: Why This Beats Aftermarket

Every page in this PDF is a direct scan of the original Yanmar publication – the same binder you’d get from a Yanmar dealer in 1996. Aftermarket parts catalogs compress images, drop the paint color table, and often substitute generic part numbers. This one keeps the original format: table of painted color, spec sheet, and all 63 figure groups. The Automotive Industry Overview discussion on parts catalogs vs. service manuals is relevant – make sure you’re buying the right document for your job. I’ve seen too many guys order a “service manual” and get a parts list, or vice versa. This is a parts catalog, period. If you need the service manual, look elsewhere. But if you need to order the correct piston kit or hose assembly, this is the only OEM source.

Frequently Asked Questions

Does this catalog cover the B22-2 P and B22-2 PR equally?

Yes. The spec table on page 2 lists both the B22-2 P[R] and B22-2 C[R] variants. The illustrations index includes all five models.

Can I use this catalog to look up engine parts for the 3TN75L-RB1?

Yes, but only the parts that are specific to the crawler backhoe application – the preface page 1 shows the engine serial range. For a full engine parts breakdown, you’d need the separate 3TN75L engine parts catalog.

How do I find the correct paint color for my machine?

The Table of Painted Color on page 3 lists each component (①②③④⑤) with the Yanmar color name, Munsell number, and the Yanmar part number for both 16L cans and spray cans. Match the callout on the machine drawing to the table.

What if my machine’s serial number is outside the ranges listed?

The preface states this is the last edition for European B22-2s, covering vehicle 30501~31409 and engine 44461~48831. If your serial falls outside, you may need a newer catalog – but in my experience, many late‑production B22-2s still use these same part numbers. Verify by comparing the figure illustrations to your machine.

Order the factory manual now. Don’t waste time with aftermarket copies that skip the paint codes or blur the hydraulic diagrams. The only way to be sure you’re ordering the genuine Yanmar part is to look it up from the original 1996 Parts Catalog. Access the Factory Manual and get back to work.
