Description

Komatsu PC450LC-7 Spare Parts Catalogue – L&T Illustrated Parts Manual

The Komatsu PC450LC-7 Spare Parts Catalogue dated 25th February 2008 is the illustrated parts reference for the PC450LC-7 hydraulic excavator. Produced under the L&T-Komatsu programme, this 364-page parts manual breaks the machine down group by group – engine, cooling, electrical, hydraulic, undercarriage, revolving frame, operator’s compartment, guards and work equipment – and pairs every exploded illustration with a numbered component list giving the part number, description, quantity per machine and applicable serial number. For anyone maintaining, overhauling or rebuilding a PC450LC-7, this is the reference that turns a vague “I need the seal for that housing” into an exact, orderable part number.

Taken as a whole, the catalogue gives a parts-level understanding of how the PC450LC-7 is assembled. Each group is treated as its own exploded view, so the reader can trace the individual bolts, seals, bushings, shims and hoses that sit behind an assembly, not just the assembly itself. The book also carries a foreword explaining the ordering convention – part number, part name, quantity, machine model code, machine serial number, engine serial number and service meter reading – plus a symbol key that covers interchangeable parts, discontinued parts, part groups, kit parts and cold-weather specifications.

How This Parts Catalogue Is Organised

The layout follows the standard Komatsu parts-book pattern. The left-hand page carries an illustration for the spare parts group, with each individual part given an index number. The right-hand page lists the components of that group in index order with the part number, part name and applicable machine serial number. Because the figure number is not a spare part number and the numbering is not always continuous, the illustration and its facing list are meant to be read together rather than searched independently. A full numerical index at the back lets you look up a part number and jump straight to the figure that uses it.

What You Can Do With This Spare Parts Catalogue

• Identify the exact part number for any component shown in the catalogue before ordering
• Confirm which serial number range a particular part applies to, so you do not fit an early or late variant by mistake
• See how sub-assemblies are built up – which bolts, washers, O-rings, seals and shims belong to a housing, cylinder, valve or motor
• Cross-check kit contents such as the cylinder block gasket kit, water pump gasket kit, shoe bolt and nut kit, and cylinder service kits against the parts you actually need
• Work through hydraulic sections – main pump, main valve, PPC valve, EPC valve, travel motor, swing motor, swivel joint – with the parts structure visible in front of you
• Support undercarriage work on the track frame, track roller, carrier roller, front idler, idler cushion and track shoe assemblies
• Cover the work equipment end of the machine, including boom, arm, bucket, bucket link and the boom, arm and bucket cylinders
• Deal with cab, seat, floor frame, monitor and air conditioner items without guessing at the fittings involved

Because the machine is broken into discrete groups, the catalogue also works as a reference for a single job rather than a full rebuild. If you are resealing a boom cylinder you can go straight to that group; if you are replacing a track roller you can go to the undercarriage group. The group boundaries in the book roughly match how the machine is actually serviced, which is what makes a parts catalogue different from a general description of the equipment.

Why a Dedicated PC450LC-7 Parts Catalogue Matters

Part numbers for a machine of this size are not guessable. A 450-class hydraulic excavator uses dozens of O-ring sizes, backing rings, seals, bushings and shims that look alike but are not interchangeable, and a wrong number means a delayed repair, a returned part or, worse, damage to a component that is difficult and expensive to remove. Having the illustrated catalogue on hand means you can match the part you are holding to the index number on the drawing, read across to the list, and confirm the number, the quantity and the serial applicability in one pass. For workshops supporting a PC450LC-7 in the field, it is the difference between ordering once and ordering twice.
