Komatsu PC350NLC-8 Parts Catalog

If you’re ordering parts for a PC350NLC-8 and you’re working from a third-party parts list, you’re probably wasting time on returns. I’ve seen it too many times – wrong bolt grade, mismatched damper pump, incorrect tube assembly. That’s why we stock the factory Komatsu PC350NLC-8 Parts Catalog – 965 pages of OEM part numbers, exploded views, and supersession data. Not a reprint. Not a scan of a scan. This is the genuine book from Komatsu.

That is 965 pages of exact part numbers.

This catalog cuts across 17 system sections, starting with B0 ENGINE RELATED PARTS at page 001000. Inside, you get every bolt, washer, damper, muffler, and DPF component for the SAA6D114E-3B engine. If you need the correct air cleaner connection for your serial number range – K50001-K50649 or K50650 and up – it’s there.

What the Komatsu PC350NLC-8 Parts Catalog Covers

The table of contents lists B0 ENGINE, CO COOLING, DO FUEL TANK, EO ELECTRICAL, GO AUTO GREASE, HO HYDRAULIC, J0 MAIN FRAME, K0 OPERATOR’S COMPARTMENT, M0 GUARD, N0 SWING CIRCLE, P0 TRAVEL PIPING, R0 UNDER CARRIAGE, T0 WORK EQUIPMENT, U0 MARKS, V0 ACCESSORY, W0 MISCELLANEOUS, and Y0 SERVICE KIT. Each section runs from page 001000 through 017000. That is full factory coverage.

7 Major System Sections with OEM Part Numbers

Among those 17, seven are the ones I see most people needing: Engine, Cooling, Fuel, Electrical, Hydraulic, Under Carriage, and Work Equipment. Those seven sections alone give you thousands of OEM part numbers. No aftermarket translation errors. For example, the damper pump tube section shows two bracket part numbers depending on whether your machine is K50986 and up. An aftermarket list would not catch that.

For the full service procedures that match these part numbers, get the Komatsu PC350LC-8 Shop Manual.

Engine Related Parts: Damper, Muffler, DPF, and Mounts

Start with B0 ENGINE RELATED PARTS on page 001000. You get the engine mount, damper pump and tube for the muffler, damper pump for the DPF, muffler with two serial number variants, air cleaner connections, and the diesel particulate filter mounting. Every part has a Komatsu number, not a generic cross-reference. I’ve seen shops order a 207-01-71310 damper from the OEM and it fits. If you try to match by photo, you’ll get the wrong one.

Understanding the operating principles of the SAA6D114E engine? Read this Wikipedia article on diesel engines for background.

Cooling System: Radiator, Fan, and Hoses on Page 002000

CO COOLING SYSTEM starts at page 002000. The radiator, fan, fan drive, hoses, and coolant pipes are all listed with their part numbers and quantities. If you need the belt for the alternator, it’s listed here. Again, serial number breaks are noted. This is one section where using a generic parts catalog will cost you time – the fan blade pitch changed mid-run.

Fuel and Electrical: Two Sections You Cannot Guess

DO FUEL TANK AND RELATED PARTS (page 003000) covers the fuel tank assembly, lines, filters, and brackets. The ELECTRICAL SYSTEM section (page 004000) includes the alternator, starter, wiring harness, and all sensors. These two sections are the ones where I see the most mismatched parts in shops. The wrong fuel line bend, or an electrical connector that doesn’t match the harness – it’s all avoidable with the OEM catalog. The aftermarket drawings omit the smaller clamps and washers that keep the system from vibrating apart.

If you need the hydraulic system breakdown, the KOMATSU Hydraulic Excavator PC350LC/NLC-8 Manual is also available on the site. For steering parts, see the FAI 67-80DT Hydraulic Steering Piston Parts List.

The engine in this machine is a six-cylinder diesel – you can read more about diesels in this Wikipedia article on diesel engines.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. Torque specs are in the shop manual.

How do I find the correct part number for the damper pump?

Open to the engine section under B0, item 1. The part number 207-01-71310 is listed for the damper. Note the serial number range: K50001 and up. If your machine is before K50945, you need bolt 01010-81225 instead of 01010-B1225. Always check the ‘Options’ column. This catalog accounts for serial number breaks, so you don’t order the wrong bolt. That’s what makes OEM documentation reliable. Also verify the pump assembly number in the service kit section – there are two supersessions depending on whether your serial number is K51272 and up or K50001 to K51271. Without this catalog, you’d have a 50/50 chance of getting the right pump.

Stop ordering parts twice. Access the Factory Manual from AutoRepairManuals and keep it on your workbench. When you have the real OEM catalog, you don’t need to call the dealer for every bolt.
