Yanmar TB228 1997 Parts Catalog – OEM Factory Specs for Compact Excavator

I'm Mike Callahan, ASE Master since '96. I've watched guys order a piston ring set three times because the aftermarket catalog showed the wrong bore size. That's wasted time and money. This Yanmar TB228 1997 Parts Catalog stops that. It's a 40-page OEM document – no guesswork, no reprints. Each figure shows the exact exploded view with factory part numbers. You want to rebuild the 3TNV82A-BPTB engine? You start here.

Every component is broken into 17 figures, from the Cylinder block (FIG01) to the gasket set (FIG17). Need a new Camshaft gear? Look at FIG07. Crankshaft components? FIG08. Cooling water pump? FIG10. Fuel injection pump or Valve? FIG11 and FIG13. The catalog even includes the governor (FIG12) and the starter motor (FIG15). You can't get this detail from a third-party list.

17 Exploded Diagrams for the Yanmar TB228 1997 Parts Catalog

Each of the 17 figures gives you a clear parts breakdown with reference numbers tied directly to Yanmar part numbers. For example, when you open FIG01 – Cylinder Block, you see every bolt, sleeve, and plug. No generic illustrations. This is the exact drawing Yanmar used on the assembly line. You match the reference number to the part number list printed on the same page. If you've ever tried to use a scanned aftermarket catalog where the numbers are blurred or cross-referenced wrong, you know why this matters.

The catalog covers the engine model [P-TB228EAB] for TB228 with engine 3TNV82A-BPTB, BPTB1. It does not cover the chassis or hydraulics – that's a different manual. But for the engine and its immediate systems, this is the authoritative source.

Cylinder Block, Camshaft, and Crankshaft: Where You Find Them

FIG01 shows the Cylinder block assembly. FIG07 is the Camshaft & driving gear. FIG08 covers the Crankshaft & piston. If you're doing a complete overhaul, you need these three figures to order pistons, rings, bearings, seals, and all the small parts like thrust washers and snap rings. The part numbers are listed with two variants depending on the engine serial number range – the catalog notes these differences. Ignore that and you might get the wrong connecting rod bearing. I've seen it happen.

What Do the Cooling and Fuel Figures Cover?

FIG10 – Cooling Water System – includes the water pump, fan, pulley, and all hose connections. FIG11 – Fuel Injection Pump – shows the pump assembly and its mounting hardware. FIG13 – Fuel Injection Valve – gives the nozzle holder, tip, and shims. FIG14 is the Fuel Line diagram. If you're replacing an injector nozzle, you need that figure to order the correct heat shield and washer. The catalog also lists the governor (FIG12) which is part of the fuel system – many aftermarket listings skip governor parts altogether.

Why Aftermarket Parts Catalogs Risk Your Rebuild

Aftermarket catalogs often combine multiple models into one list, making mistakes in supersessions and omitting engine-specific variations. This Yanmar TB228 1997 Parts Catalog is the original factory document. The Automotive Industry Overview Automotive Industry Overview Automotive Industry Overview years of standardized parts numbering, but only the OEM manual gives you the exact drawing and number for your specific machine. If someone brings a TB228 into my shop with a part that doesn't fit, I pull this catalog and prove them wrong.

Use This Catalog Alongside the Service Manual

This parts catalog works hand-in-hand with the service repair manual. The service manual tells you how to remove and install – this catalog tells you what to order. Torque specs and procedures are in the service manual, not here. Don't buy this thinking it has assembly instructions. It's a parts identification tool. Pair it with the Yanmar TB228 Service & Repair Manual for a complete rebuild package.

Does this catalog include torque specifications?

No, this catalog lists part numbers only, not torque specs.

How do I find the right part number if my serial number isn't listed?

The catalog groups parts by engine model designation (P-TB228EAB) and variant suffixes (A/B/C etc.). If your serial number isn't directly matched, look at the engine model plate on the valve cover. The 3TNV82A family has subtle differences in fuel pump and governor parts. Cross-reference with the figure number that matches your engine configuration. If you still can't match, call Yanmar with the engine serial – they will reference this same catalog to confirm the part number. That's why having the OEM catalog on hand is critical – you can show the dealer exactly which figure and reference number you're looking at, eliminating phone tag.

Can I use this catalog for a 3TNV82A engine in a different machine?

Possibly, but only if the engine badge matches exactly (3TNV82A-BPTB or BPTB1). The TB228-specific chassis parts like the flywheel housing (FIG03) may differ from other Yanmar models that use the same base engine. Stick with the model listed.

Does this catalog cover the entire machine or just the engine?

It covers the engine and its immediate systems – cylinder block, head, fuel, cooling, lubrication, starting/charging. It does not include undercarriage, hydraulic pump, or control valves.
