Yanmar B27-2A(C)FRT, B27-2A(C)SID, B27-2A(P)FRT, B27-2A(P)SID, B27-2A(C)EX 1998 Parts Catalog

You’ve got an old Yanmar crawler backhoe sitting in the yard. Maybe it’s a B27-2A(C)FRT with a cab, or a B27-2A(P)SID canopy model. You need a fuel line, a valve assembly, or an engine mount – and the aftermarket catalogs are useless. Wrong part numbers, missing illustrations, and no guarantee the stuff fits. That frustration ends with this 1998 Yanmar Parts Catalog – the last OEM edition, 239 pages, direct from the factory.

Parts Coverage: Engine, Fuel, and Valve Systems

This isn’t a service manual – it’s a parts catalog. But if you’re rebuilding the 3TNE82A-B1 diesel engine or tracing a fuel leak, you need the correct part numbers for each component. The catalog breaks down every system: Engine mounts and accessories (Fig.13), Fuel tank and lines (Fig.15), and multiple Valve assemblies – rotary valves, remote control valves, and the P.T.O. valve. Page 1 warns you against using non-genuine parts; I’ve seen what cheap aftermarket valves do to a hydraulic circuit. Stick with this OEM guide.

What’s Inside the 239-Page Parts Catalog?

Two hundred thirty-nine pages of exploded diagrams. Each figure corresponds to a specific system – from Fig.24 Radio to Fig.104 Blade. The illustrations are simplified, but every part has a reference number and description. You get the paint color codes (Yanmar New Permanent Yellow, Mint Green, etc.) and specifications on page 2: engine model, transport dimensions, bucket capacity, digging depth. Need the ground pressure spec? It’s right there: 0.27 kgf/cm² for steel crawlers. That matters when ordering undercarriage parts.

Why OEM Yanmar Documentation Beats Aftermarket

Aftermarket catalogs often copy old data, skip figures, or mix up model variants. This is the real thing – Yanmar’s last edition published June 1998 (Part No. 000Y00K3271). It covers five specific models: B27-2A(C)FRT, B27-2A(C)SID, B27-2A(P)FRT, B27-2A(P)SID, and B27-2A(C)EX. Each variant has different cab or canopy setups and lever configurations. If you’re working on an EX (Australia/Overseas) model, the standard parts catalog won’t cut it. This one does.

I’ve torqued enough bolts to know that guessing part numbers costs time and money. A misidentified hydraulic pump joint (Fig.47) means waiting another week for the right seal. This catalog eliminates that guesswork.

Fig. 15: Fuel Tank & Fuel Line – What You Need

Fuel system diagrams are where most aftermarket catalogs fall flat. They show a generic tank and line, but the B27-2A has specific routing for the cab vs. canopy versions. Fig.15 in this catalog gives you the exact part numbers for the fuel tank, lines, and clamps. If you’re replacing a cracked line on a B27-2A(C)SID, you can cross-reference the illustration and order the correct hose without measuring bends by hand.

3 Model Variants You Need to Know About

Five model codes, but three main configurations: Cabin with Front or Side lever (C)FRT / (C)SID, Canopy with Front or Side lever (P)FRT / (P)SID, and the EX models for Australia and overseas (Cabin or Canopy). The chassis, hydraulic piping, and even the bonnet design differ. Page 1 of the catalog lists each spec clearly. Do not assume a part from a (P)FRT will fit a (C)EX – check the figure first.

Access the Factory Manual for Your Yanmar B27-2A

This catalog is a PDF – you can search for part numbers, zoom into diagrams, and print only the pages you need. Keep a copy on your tablet next to the machine. If you’re restoring a B27-2A(P)FRT or rebuilding a B27-2A(C)EX, you need the OEM parts breakdown. Related manuals worth checking: Ammann Yanmar B12 B17 Parts Catalog for smaller models, Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs if you have an older variant, and Yanmar YB301 YB351 1991 Parts Catalog – 248 Pages OEM for the bigger cousins.

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. It shows exploded views and part numbers only. You need the separate service manual for torque values.

Can I use this to order parts for a B27-2A(P)EX model?

Yes – the catalog covers the B27-2A(P)EX variant under Section I (Vehicle), column F. The same figures apply, but check the model column carefully for any EX-specific differences.

What about the engine? Does it show the 3TNE82A-B1 parts?

Section II (Engine) lists the 3TNE82A-B1 with its own set of illustrations. You’ll find piston rings, gaskets, and injection parts – all OEM.

How do I know if I need the Front lever or Side lever version?

Look at your machine’s control layout. Front lever machines have the joystick mounted ahead of the seat; side lever machines have it on the right. The catalog lists both: (C)FRT / (P)FRT for front, (C)SID / (P)SID for side. Match your serial number to the correct column in the preface (page 1).
