Komatsu D65EX-17, SAA6D114E-5B Parts Catalog

If you’ve been wrenching on heavy equipment long enough, you’ve had that moment—a part shows up, doesn’t match the hole, and you’re staring at a week of downtime. That’s why you need the Komatsu D65EX-17, SAA6D114E-5B Parts Catalog open on your bench. This is the OEM document, not some third-party scan that swapped a ‘6’ for an ‘8’ on a gasket number. 1000 pages of factory-fresh illustrations and part numbers, straight from Komatsu.

I’ve been a master tech for 28 years. I know the difference between a catalog that saves a job and one that costs you a Saturday.

Engine Cylinder Head and Its Related Parts

This section alone covers over twenty figures, starting with the cylinder head itself (Fig. A1009-001001) and running through the rocker arm housing, Komatsu Variable Geometry Turbocharger (KVGT), EGR valve, and the Komatsu Diesel Particulate Filter (KDPF). Every exploded view gives you index numbers that tie directly to the parts list. Need a valve stem seal? You’ll find it under the Cylinder Head figure—part number, quantity, and any supersession code (A1, A2, etc.) printed right there. No flipping between pages hoping the numbers line up.

What Makes This Parts Catalog Different from Aftermarket?

Aftermarket catalogs often combine multiple model years into one chart, cutting corners on serial-number breaks. This one is specific to the D65EX-17 with serial number 2116 and up, and the SAA6D114E-5B engine with serial 26901773 and up. Page 2 of the foreword tells you exactly how to read the code columns—A1 for interchangeable, B1 for discontinued, C1 for assemblies that can’t be purchased piecemeal. That kind of precision keeps you from ordering a head cover that won’t clear the KVGT.

5 Major Systems Documented

The catalog splits the engine into five main groups: Engine Cylinder Head, Engine Cylinder Block, Engine Lubrication System, Engine Fuel System, and Engine Cooling System. Each group contains sub-figures for every assembly. For example, under Cylinder Block you’ll find the crank, piston and connecting rod, oil pan, flywheel, and the front gear train. Under Lubrication you get the oil pump, filter, and cooler. Fuel system covers the supply pump, filter piping, drain lines, and injector-related parts. Cooling includes fan drive, pulley, belt tensioner, and water pump piping. If it’s on the engine, it’s in here.

Komatsu D65EX-17, SAA6D114E-5B Parts Catalog: A Technician’s Perspective

Every time I order parts for a D65EX-17, I pull up this catalog before dialing the distributor. You can cross-check the part number with the illustration to make sure the flange shape matches, the bolt-hole pattern lines up, and the quantity per assembly agrees with the figure. That’s especially critical on the KVGT oil piping or the EGR cooler water piping—wrong banjo bolt and you’re pulling the cab off again. The catalog even includes a separate set of figures for landfill specification machines, so if you’re working on a garbage-compacting version, you get the correct heat shields and exhaust parts.

Use the Right Part Number the First Time

Look at the exhaust manifold section: there’s one for standard and one for landfill spec (Fig. ATB30-002001). The index numbers are the same but the part numbers differ. If you order the standard manifold for a landfill machine, the EGR pipe won’t reach. That’s a $400 mistake. With this catalog, you check the figure title, note the serial number range, and order the exact piece. Trust the OEM number. No guessing.

KVGT Turbocharger: Detailed Figure Breakdown

The Komatsu Variable Geometry Turbocharger gets its own set of figures—KVGT related parts, KVGT for landfill, KVGT oil piping. Each figure shows every clamp, gasket, and bracket. The heat shield section (Fig. A1570-001001) covers both the KVGT and the KDPF, so you see how they nest together. That kind of assembly awareness saves you from knocking a heat shield loose later.

Does this catalog include torque specs?

No. It lists parts and part numbers only.

How do I find a specific part?

Look up the figure for the assembly that contains the part. Each figure has an exploded diagram with index numbers. Match the index to the parts list below the figure; that gives you the part number, description, and quantity. If the part is part of a sub-assembly, the catalog uses a dot system (• for sub-components, •• for sub-assemblies) to show the hierarchy. For example, under Rocker Arm Housing you’ll see the housing itself, then the rocker arm shaft, then the individual rocker arms as indented items. The figure number is printed on every page, so you can flip back and forth without losing your place. Start with the Table of Contents that groups figures by engine system—Cylinder Head, Block, Lubrication, Fuel, Cooling.

Is this for the D65PX or D65WX variants?

This specific catalog covers the D65EX-17 with serial 2116 and up, engine SAA6D114E-5B with serial 26901773 and up. Dozer variants have their own catalogs. For the workshop manual covering all three undercarriages, see our related KOMATSU D65EX-17 D65PX-17 D65WX-17 Workshop Manual.

Can I use this for earlier serial numbers?

No. The catalog explicitly states serial number 2116 and up for the machine, 26901773 and up for the engine. Using it for earlier machines will likely give you wrong part numbers. Check your machine’s serial plate and match it to the foreword page before ordering. If you have a different engine, we also carry the Komatsu WH609-1 WH613-1 Parts Catalog | 347 Pages OEM for those power units.

This job is hard enough without fighting part-number errors. The Komatsu D65EX-17, SAA6D114E-5B Parts Catalog puts the factory drawing on your screen, not a photocopy of a photocopy. Every figure is clear, every code column is explained in the foreword, and every part number traces back to an OEM bin. If you’re also working on hydraulics, the FAI 67-80DT Hydraulic Steering Piston Parts List might save you a headache.
