Fiat-hitachi EX300-5, EX300LC-5, EX330LC-5, EX350H-5, EX350LCH-5 Parts Catalog
Ordering the wrong part because you guessed the serial number break or trusted a third-party listing is a waste of time. Worse, it holds up the machine. That is exactly why this Fiat-hitachi EX300-5, EX300LC-5, EX330LC-5, EX350H-5, EX350LCH-5 Parts Catalog exists – to put the factory part numbers and exploded-view diagrams in your hands, not some aftermarket rehash.
Engine and Fuel System Coverage
Every parts listing for the Engine and Fuel system is broken down by model variant. The ENGINE section (from the TOC) lists each component – mounts, support brackets, gaskets. The FUEL TANK, FUEL PIPING, FUEL FEED PUMP (SELECT), and FUEL DOUBLE FILTER (SELECT) sections are all separated. You will find the exact O-ring or hose part number for the EX300LC-5 vs the EX350H-5. Page 73 covers the fuel tank support and piping routing for standard-track and LC-track machines.
334 Pages of Factory Part Numbers
This is a 334-page OEM document, not a third-party compilation. Each page has a parts illustration with reference numbers, the corresponding Fiat-hitachi part number, description, quantity per machine, and service codes like W (on-site modification needed) or D (not sold individually). The back of the catalog includes a numerical parts index so you can reverse-lookup any number.
Does This Manual Cover the Entire Machine?
Yes – from the UPPERSTRUCTURE frame down to the CAB GROUP and PILOT PIPING. The TOC lists over 150 section titles. For example, the COUNTERWEIGHT 6.8T (for EX300,EX300LC) is separate from COUNTERWEIGHT 7.55T (for EX350H,EX350LCH) and COUNTERWEIGHT 8.2T (for EX350K,EX350LCK). You get the right weight and bolt set for your specific model.
Counterweight Variations Across Models
Counterweights are not interchangeable between the EX300-5 and the EX350H-5 without drilling new holes. This catalog lists the exact counterweight assembly part numbers for each variant: 6.8 ton for <300,LC>, 7.55 ton for <350H,LCH>, and 8.2 ton for <350K,LCK>. Each one has its own mounting bracket and hardware kit.
Source Validity: OEM vs Aftermarket Copies
Aftermarket parts catalogs often skip the service codes, omit the [USA] or [AUS] regional variations, or fail to note that EX330LC-5 is identical to the EX300LC-5 for North America (as stated on page 4 of the original). This manual carries the Fiat-hitachi part number PIHI-1-3 printed on the cover. Every exploded diagram matches the actual production machine. I trust this one. Do not rely on a PDF that was scanned from a library copy with missing pages.

FAQ
- Will this manual list the right part for my EX330LC-5?
- Yes. The catalog explains on page 4 that EX330LC-5 is a North American designation for the same machine as EX300LC-5. All part numbers for <300,LC> apply.
- Does it include the electrical system parts?
- Yes. The ELECTRIC PARTS sections (A through F) cover everything from the controller and monitor to the front head lamps, boom light harness, horn, swing alarm, and travel motion alarm.
- Can I use this to order engine internal parts?
- No. Engine internal parts (pistons, liners, etc.) are in a separate Isuzu diesel engine parts catalog (B-6SD1TQA-01). The manual notes this on page 4. This catalog covers everything outside the engine block.
- How do I interpret the service codes in the columns?
- Each code is explained on page 5 of the manual. For instance, “D” means the part is only sold as an assembly – you cannot buy the single piece. “K” means it is included in a service parts kit. The code appears next to the part number in the listing. Do not ignore these codes or you will order a part that cannot be installed alone.
