Yanmar 3TNV76-GGE Parts Catalog

Every time a technician pulls a part number from a third-party list and gets the wrong flange, wrong gasket, or wrong injector line, they lose billable hours and trust. I’ve seen it happen on a 3TNV76-GGE in a mini-excavator that sat down for three days waiting for a reorder. That’s why Yanmar 3TNV76-GGE Parts Catalog from the factory matters. It’s 31 pages of exploded views and OEM part numbers for the TNV series diesel engine — not a compilation from some editor who never held a wrench. You get the same documentation Yanmar dealers use to pull parts for warranty claims. If you’re rebuilding a cylinder head or chasing an oil leak, you need the exact reference, not a guess.

Engine Section Breakdown: Cylinder Block to Gasket Set

The catalog is organized by physical engine groups. Starts at the foundation: CYLINDER BLOCK (Fig. 1). Page 3 shows the block assembly with cast part numbers and notations for over-size (O.S=0.25) and under-size (U.S=0.25) components. You’ll see main bearing sets, cylinder head bolts, and the camshaft bushings laid out by application code — (B)=3TNV76-GGE specific. After that comes GEAR HOUSING on page 4, covering the timing cover, oil pump rotor assembly, relief valve spring, and the knock pipe. The gear case covers are listed by variant (three different part numbers depending on exact engine suffix). That kind of granularity is missing from generic lists.

7 Systems Covered: Cooling, Fuel, Lubrication

One section per major system. COOLING WATER SYSTEM (section 10) has its own page with water pump and thermostat parts. FUEL INJECTION PUMP appears twice — sections 11 and 13 — because there are two different pump configurations used on the 3TNV76-GGE. The LUB.OIL SYSTEM (section 9) breaks down the oil cooler, filter base, and pressure valve components. If you need the FUEL INJECTION VALVE (section 15) or FUEL LINE (section 16), they’re here with the exact banjo bolt and washer part numbers. The GOVERNOR sections (12 & 14) show the internal spring and pin assemblies that often get swapped during pump rebuilds.

Camshaft & Driving Gear: What the Parts Catalog Shows

Section 7 covers the CAMSHAFT & DRIVING GEAR. The drum shows the camshaft part number, thrust plate, and idler gear assembly. If you’re replacing a worn gear on a high-hour engine, the catalog lists the matching keyway and bolt torque reference — though torque values belong in the service manual, not this parts book. What this catalog gives you is the confidence that the gear you order will mesh with the existing crank gear. OEM part numbers match the physical casting numbers on the parts themselves. That alone saves an hour of cross-referencing every time.

Does This Manual Cover the Generator and Starter Motor?

Yes. Sections 17 and 18 list the STARTING MOTOR and GENERATOR (alternator) with all mounting brackets, pulleys, and wiring harness part numbers. The catalog includes optional parts tags — note the gear housing cover options flagged as (1) OPTIONAL PART. If your machine came with a different alternator from the factory, the variant column (A through F) shows which part fits which engine code. For a 3TNV76-GGE with serial number falling in a certain range, you’ll see the correct rotor and stator references. This level of detail is not available in aftermarket catalogs.

Why OEM Parts Catalog Beats Aftermarket Lists

I’ve watched a shop order an aftermarket gasket set for a TNV series engine and get a head gasket that was 0.3 mm too thick — combustion loss, no compression, wasted weekend. The OEM catalog includes the GASKET SET (section 19) with individual gasket part numbers that match the cylinder head, manifold, and oil pan flanges. You can order exactly what you need without buying a full set. Aftermarket aggregators often combine part numbers from different Yanmar models (3TNV76-HGE, 3TNV76-NBK) into one list. This catalog keeps them separate by application code. Page 3 of the cylinder block section explicitly codes the block for (B)=3TNV76-GGE. That’s the kind of verification you need when the engine stand is holding up a production line.

FAQ

Is this a service manual with repair procedures?

No. This is a parts catalog only — 31 pages of exploded diagrams and OEM part numbers. You need a separate service manual for torque specs and disassembly steps.

What does the catalog include for the fuel injection system?

Fuel injection pump, governor, injection valve, and fuel line sections. Each lists the pump body, delivery valve holder, plunger and barrel assembly, and the specific injection pipe part numbers for the 3TNV76-GGE configuration. There are two different pump groups because this engine was fitted with both Bosch and Yanmar pumps depending on production date. The catalog shows both with separate part numbers.

Can I use this to cross-reference parts with other Yanmar models?

Yes, the catalog includes column codes (A through F) that match part usage across models like 3TNV76-HGE and 3TNV76-NBK. But you should only order the part number listed under your specific model code to avoid mis-matches.

Are exploded diagrams included?

Yes, each section has a figure number with an exploded view and a parts table with reference numbers, descriptions, and quantities per engine.

After you’ve spent half a morning trying to match a casting number off a rusty oil pan, you’ll appreciate having the factory catalog open on the screen. The Yanmar 3TNV76-GGE Parts Catalog is an exact replica of what the dealer parts counter uses. Find your cylinder block variant, get the correct camshaft bushing, and order the right gasket set without the return-shipment headache.
