Fiat-hitachi EX60-3, EX60LC-3 Parts Catalog

You’ve been there: you need a seal kit for the main pump, so you grab a generic listing from an aftermarket site. The package arrives, and the piston bore is wrong, or the control spool doesn’t match your serial number break. That’s a parts order down the drain, plus a machine sitting idle. The Fiat-hitachi EX60-3, EX60LC-3 Parts Catalog eliminates that guessing. This is the same 118-page document that dealer parts counters use – factory-issued, with exact part numbers for every hydraulic component on these excavators.

Pump and Motor Sections: What This Catalog Covers

Page 1 stamps the model and serial number range (40001~) so you know this catalog applies to your machine. The PUMP section alone is split into piston pump (main), blade pump, vibrator pump, and gear pump – each with its own control, hanger, rotary group, cover, and case subassemblies. You get exploded views and callouts for every bolt, shim, and seal. If you’re rebuilding the travel motor or swing motor, the MOTOR;OIL section lays out the swing motor (parts 1/2 and 2/2), travel motor, and the relief valve that bolts directly onto the motor housing. No more ordering a “universal” travel motor seal kit that doesn’t fit your EX60-3’s serial breaker.

Does This Manual Cover the Valve Assembly in Detail?

Absolutely. The VALVE section is the thickest part of the catalog. It breaks down the control valve into three spreads (1/3, 2/3, 3/3) plus a separate offset boom control valve. You get the pilot valve, solenoid valves (multiple variants), FC valve, relief valve, lock valve, and slow-return valve. Each valve assembly shows every internal component – springs, poppets, seats, and O-rings. Need to identify the exact relief cartridge for your arm circuit? The exploded view and part number are right there. The catalog also includes service codes (W for field modification, D for assembly-only replacement, K for kit availability) so you know if that valve can be serviced individually or must be replaced as a unit. That kind of detail saves you from tearing apart a valve bank only to find out the part you need isn’t sold separately.

118 Pages of Factory-Indexed Parts

Every page in this 118-page document is original OEM – not a scanned reprint with missing pages. The back of the catalog includes a complete Parts Index that lists every part number in numerical order. You cross-reference a number you find on an existing component, and the index sends you to the correct exploded view page. No flipping through blurry aftermarket diagrams trying to match a worn-out part by eye. The index also marks new parts with an asterisk, so you can spot revisions made after your machine left the factory.

Understand the Valve System Before You Order Parts

The hydraulic system on these Hitachi machines uses a complex network of valves. The catalog’s valve section is organized by function – control, pilot, solenoid, FC, lock, slow-return. If you’re working on an offset boom configuration, there’s a dedicated control valve subsection (OFFSET BOOM) that covers the extra spool and lines. Don’t assume all EX60-3 control valves are the same; the three sub-sections (1/3, 2/3, 3/3) correspond to different spool stacks. Grabbing the wrong spool for a machine with a blade? The catalog’s blade cylinder section and the blade pump section in the PUMP chapter cross-reference exactly to the correct valve porting. This level of specificity keeps you from ordering a $500 valve that doesn’t fit.

Why OEM Documentation Matters for the EX60-3 and EX60LC-3

Aftermarket parts catalogs often combine multiple revision levels into one diagram, leaving you to guess whether the part number is current for your serial number. This Fiat-hitachi catalog is the original factory document – the same one the engineers used when assembling the machine. Page 5 includes the foreword with ordering instructions (serial number, part number, part name, quantity, delivery address) and explains orientation conventions: boom side is front, engine side is rear, operator’s side is left. That orientation is critical when you’re ordering a Valve subplate that has a specific inlet location. The catalog also uses Japanese and English text, so you can cross-check terminology. For more background on why OEM documentation is the standard in the automotive and heavy equipment industry, see the Automotive Industry Overview. And for similar manuals on related models, check the HITACHI EX60-3 EX60LC-3 Parts Catalog (the same product) or the Fiat-hitachi 850-3, 850LC-3, 870H-3, 870LCH-3 Parts Catalog and Fiat-hitachi ZX50U-2 Parts Catalog – 120 Pages of OEM Specs.

Can I find part numbers for the EX60LC-3 in this same catalog?

Yes. The catalog covers both EX60-3 and EX60LC-3 models.

How do I order parts using this catalog? What information do I need?

Page 5 details the ordering procedure. You need the machine model (EX60-3 or EX60LC-3), the machine serial number (located on the main frame plate under the cab), the part number from the catalog, the part name (e.g., 0-リング), quantity, and your shipping address. The catalog also includes service codes: W means field modification required, D means assembly-only replacement (cannot order the single part), K indicates a service kit, R means quantity varies per machine (shims), S means service-only part not assembled at factory, OP for optional, OS/US for oversize/undersize. Having this information ready keeps your parts order from getting kicked back. Aftermarket catalogs rarely list these codes, which is why you get the wrong part delivered.
