Komatsu D65PX-17 Parts Catalog – 838 Pages of Factory Engine Parts

If you’re ordering parts for a Komatsu D65PX-17, you need the exact part number – not a guess, not a cross-reference from a third-party site. I’ve been wrenching 28 years, and I’ve seen what happens when someone orders a “looks-about-right” piston ring. Week of downtime, wrong parts, and a phone call to the dealer who wants the serial number. This Parts Catalog saves that headache. 838 pages of OEM exploded views and part lists straight from Komatsu. No reprints.

Engine Cylinder Head: 19 Figure Sheets

This catalog starts with the cylinder head and everything bolted to it. From the rocker arm housing (FIG. ARL00-001001) down to the heat shields for the KVGT turbo and KDPF filter. You’ll see the Komatsu Variable Geometry Turbocharger oil piping and the EGR cooler water piping – all drawn with index numbers that match the parts list. Need the part number for the exhaust connector clamp? FIG. AXS00-001001. The cylinder block section comes next, with 21 figure sheets covering front gear covers, flywheel housing, pistons, connecting rods, and the vibration damper. The manual even breaks down the front gear train plugs and tappet locations. If you’re rebuilding an Engine out of a D65PX-17 with serial number 1528 and up, you’ll want to bookmark the cylinder block page.

Lubricating and Fuel Systems: What the Parts Catalog Covers

Two separate sections – lubricating system and fuel system. The oil pump, oil filter, oil cooler, coolant vent parts are all there. The fuel section covers the injection pump, fuel supply pump support, piping, filters, and drain lines. Each part has a code column showing interchangeability (A1, A2 codes) or if it’s discontinued (B1) or supplied only as an assembly (C1). That’s the kind of info you don’t get from a generic parts PDF. It prevents you from ordering a part that won’t work because the machine serial number range changed. The manual explicitly lists which serial numbers apply – D65PX-17 serial 1528 and up, engine SAA6D114E-5B serial 26900063 and up.

3 Things That Make This OEM Book Different from Aftermarket Junk

Aftermarket catalogs often mash years together or omit the “Code” column that tells you if a part is superseded. Not here. Each parts list has a part number, description, quantity, and applicable serial number. The “Code” column uses symbols like A1 (interchangeable with line above) and C2 (distributor-only assembly). The manual even includes C3 for semi-finished parts that need additional work before installation – something you’ll never see in a third-party reprint. I’ve been burned by aftermarket documentation that reused old part numbers. Trust the factory print.

How to Use the Figure Numbers and Parts List

Open the catalog and you’ll find an illustration with a FIG number (like FIG. A1009-001001 for Cylinder Head). Each part has an index number. Flip to the parts list page and index numbers are listed in order. The part number is the key – it’s the identification code when ordering. Write it down exactly. The manual also gives the part name and any assembly context (dots indicate sub‑assembly levels). This is the same system Komatsu dealers use. If you’re working with a KOMATSU D65EX-17 D65PX-17 D65WX-17 Workshop Manual alongside this parts catalog, you’ll have the full picture: torque specs from the workshop manual plus part numbers from this catalog.

Cooling and Electrical Systems: Not Overlooked

Separate sections for cooling fan drive, water pump, thermostat, alternators (60A and 90A), starting motors (7.5kW and 11kW), and wiring harnesses. The hydraulic pump section is also included – FIG. AHD10-001001 and AHD20-001001. These are often the assemblies that fail on a dozer. Having the exact part number for the water pump drive belt (two options based on alternator output) saves a trip back to the shop. The electrical section even breaks down alternator covers and mounting parts. You can see which wiring harness goes with which serial number.

Does This Parts Catalog Include Torque Specs or Repair Instructions?

No. This is a parts catalog, not a service manual. It lists parts, quantities, and codes for ordering – not torque values or step‑by‑step disassembly. For that, you need the workshop manual linked above. But when you’re standing at the parts counter or searching online, you need the correct part number. That’s what these 838 pages deliver. I’ve seen too many guys order a “Komatsu D65PX-17 head gasket” from a third-party site and get the wrong one because they didn’t verify the engine serial. This catalog ties the part to the exact engine (SAA6D114E-5B) and machine series.

FAQ

Is this the official Komatsu Parts Catalog?

Yes. It’s the factory PDF – same one dealers use. 838 pages, original OEM prints.

Can I use this catalog to find parts for a D65PX-17 with a different serial number?

This edition covers D65PX-17 serial 1528 and up, and engine serial 26900063 and up. If your machine is outside that range, some parts may have changed. Check the code column for interchange or discontinued indicators.

Does the catalog include part numbers for aftermarket alternatives?

It lists only genuine Komatsu part numbers. No cross‑references. But that’s what you want – you can give that part number to any Komatsu distributor or search it online. Aftermarket sites often create their own part numbers, which leads to mismatches.

What about the EGR cooler and KDPF parts – are they in there?

Yes. Three figure sheets cover the EGR cooler (air piping, water piping, and the cooler itself). The KDPF is split into two sheets – FIG. A1610-001001 and A1610-001002. Plus the heat shields for the KVGT and KDPF. All part numbers are listed.

If you’re ordering a part for a Komatsu D65PX-17 and don’t want to gamble $200 on the wrong component, this is the file that gives you the factory part number. No guessing, no cross-referencing. Open the PDF, find the FIG number, read the part number, and order it.
