Nissan BD3004 1996 Parts Catalog

You’ve got an engine torn down, a pile of bolts labeled with masking tape, and you’re trying to figure out which crankshaft pulley matches the serial number stamped on the block. That’s when you realize the aftermarket parts book you obtained last year has the wrong illustration for the front cover. I’ve been there. The Nissan BD3004 1996 Parts Catalog is the only document that keeps you from ordering a cylinder head that doesn’t fit. 111 pages of factory-correct exploded views and part numbers, not a generic reprint. No guesswork.

Why You Need the Nissan BD3004 1996 Parts Catalog

Every time I see a junior tech order a fuel injection pump based on a picture from a third-party website, I wince. The BD3004 is used in TB070 industrial engines across multiple equipment manufacturers — Hitachi, standard construction machinery, power units. One wrong nozzle holder and you’re chasing a misfire for two days. This catalog has an Applicable Model Table and Specification Combination Table (page 2 of the bookmarks) that matches your application number (APP. NO.) to the correct section. You don’t guess; you trace the APP. NO. from the machine builder’s model number, then pull the right parts list. That’s the difference between a job that pays and a job that eats your Saturday.

Cylinder Block to Flywheel Housing: Engine Core

Section BLOCK, OIL PAN, FRONT COVER, FLYWHEEL HOUSING is where you start if the long block is on the stand. It covers the overhaul kit for the engine, the cylinder block itself, oil pan, front cover, and flywheel housing. You get individual part callouts for every seal, bearing, and bolt. If you need the correct oil cooler gasket for a 1996 build, this is where you find it. The CYLINDER BLOCK subsection includes the exact casting number — don’t trust a parts store database that says “fits all BD3004 models” because later production runs changed the front cover bolt pattern. The catalog shows it.

Valve Mechanism and Crankshaft Assembly

Under HEAD, PISTON, CRANKSHAFT, PULLEY, FLYWHEEL, VALVE MECHANISM you get the complete valve train: cylinder head, piston and crankshaft group, crank pulley and flywheel, and the valve mechanism. This is critical for a top-end rebuild. The PISTON & CRANKSHAFT illustration includes the connecting rod assembly and the crankshaft thrust washers. You’ll see the valve spring part numbers — and yes, the intake and exhaust springs are different on some build dates. Use the engine number range given on the page to confirm you’re ordering the right set. Page references in the catalog are keyed to the illustration numbers (FIG. NO.) so you never accidentally buy a cylinder head for a different application.

Fuel System: From Injection Pump to Nozzle

The FUEL SYSTEM section is massive: six subsections covering piping, nozzle and holder inner parts, fuel injection pump (both fitting and inner parts), governor inner parts, feed pump, and coupling. If you’re pulling a pump off a TB070, you need the coupling section — cotter pin size, spring washer quantity, the whole deal. There’s also a separate FILTER-FUEL group with fitting and inner parts, and a dedicated SEDIMENTER-FUEL section for the water separator. You want the correct FUEL INJECTION PUMP for APP. NO. 03 vs APP. NO. 04? The catalog lists each. No more returning the wrong pump because the parts counter guy looked it up by “BD3004” without the application number.

7 Systems Covered: Engine, Fuel, Cooling, Electrical, Accessories

The catalog organizes the BD3004 into seven major systems: Engine (block, head, valve train), Manifold & Air Intake (with air compressor and oil pump/filter), Fuel System, Cooling System (water pump, thermostat housing, oil cooler, radiator), Electrical Parts (generator and starter motor with inner and fitting parts), and Accessories & Tool section. There’s also a Parts Index at the back (page 111) to cross-reference by part number. The COOLING SYSTEM-FAN subsection includes the fan blade part numbers — crucial because some TB070 chassis use a different fan offset depending on the radiator shroud. You won’t find that in a generic manual.

Source: Factory OEM vs Aftermarket Catalogs

This isn’t a scanned copy of a third-party compilation. It’s the original Nissan Diesel publication (Pub.No.PBD34 39607), released July 1996. The APPLICBLE MODEL TABLE and SPECIFICATION CONMINATION TABLE are factory-verified. Aftermarket catalogs often combine parts from multiple engine families into one diagram, then slap a disclaimer saying “subject to change.” That gets you an oil pan that has the wrong drain plug location. This catalog uses specific engine number cutoffs (E/#013223 onward for most applications, E/#000001 for Hitachi) — you match your engine number and you’re done. That’s how you avoid buying a crankshaft that won’t fit your damper. For a broader look at the industry, see the Automotive Industry Overview for context on why OEM parts databases are the gold standard. And if you’re also working on older Nissan industrial power units, the NISSAN BD3004 1996 Parts Catalog is your starting point; but you might also need the NISSAN 250 Series 1986 Parts Catalog for the bigger displacement engines or the Nissan 410 Parts Catalog for the smaller marine variants. Battery-related components? Check the Automotive Battery reference for starter motor specifications.

Does this catalog include torque specifications for cylinder head bolts?

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

How do I use the catalog if my engine number is before the cutoff range listed in the introduction?

That’s a common pain point. The introduction states the catalog covers BD3004 engines from E/#013223 onward (and E/#000001 for Hitachi). If your engine number is older, you must use the earlier parts catalog for that production batch — the cylinder block casting and crankshaft part numbers changed. The application tables (APP. NO.) in this catalog reference only the later build series. If you try to order parts for a pre-cutoff engine from this book, you risk getting the wrong front cover and valve mechanism components. Always verify your engine number against the list on page 10-006 of the catalog. If it doesn’t fall in the range, stop and source the correct older publication. I’ve seen three jobs go sideways because someone assumed “BD3004” meant all parts interchange. They don’t. Engine number is the law.

When you’re staring at a disassembled fuel injection pump or trying to decode the part number stamped on a cracked cylinder head, this catalog is the only document that tells you exactly which part to order. No cross-referencing ambiguous aftermarket charts. No calling the dealer and hoping the kid on the phone reads the right microfiche. You get the factory diagram, the factory part number, and the factory application matrix. Access the Factory Manual and stop burning labor hours on parts returns.
