Komatsu PC400-7 Excavator Parts Catalog PDF – SAA6D125E-3 Spare Parts Manual

Description

The Komatsu PC400-7 Excavator Parts Catalog PDF is the complete illustrated spare-parts reference for the PC400-7 hydraulic excavator and the SAA6D125E-3 diesel engine that powers it. It covers machine serial numbers J20001 and up and engine serial numbers 312635 and up. Every major assembly is drawn as an exploded figure next to a parts list showing reference number, part number, description, quantity and the serial-number range each part applies to, so a workshop, parts counter or owner can positively identify a component before ordering it.

Put together, the Komatsu PC400-7 parts catalog covers the machine from the cylinder block outward: fuel, cooling and engine electrical systems; the hydraulic tank, main pump, main valve and every line group; the revolving frame and operator’s compartment; the undercarriage and track assemblies; and the whole boom, arm and bucket work equipment. Each figure is keyed to a numbered parts list, so once a component is located on the drawing the corresponding part number, quantity and serial-number breakpoint can be read directly from the adjacent table.

How the parts lists and symbols work

Every figure in the Komatsu PC400-7 spare parts manual is laid out with an index number, part number, description, quantity and serial-number range. The catalog also uses the standard Komatsu parts-list symbols, and reading those correctly is what stops a part being ordered that has already been replaced. The symbols flag interchangeable parts, parts that can be used instead of the line above, discontinued parts where a superseded number is supplied, kit-only items, semi-finished parts, and painted parts. There are also cold-weather specification codes (A) for -30 C machines and (B) for -50 C machines, so the correct climate-spec part can be selected without ordering the wrong variant.

What the PC400-7 parts catalog lets you do

With the Komatsu PC400-7 Excavator Parts Catalog PDF open, a technician or parts counter can identify a component from the exploded view, read its part number, confirm the correct quantity, and check whether the part is subject to a serial-number breakpoint or has been superseded. That means fewer wrong orders, fewer returns, and no reliance on memory or guesswork when rebuilding a cylinder head, a swing motor, a travel motor, a hydraulic line group or an undercarriage section. The catalog covers the main valve in twenty separate sections, the main pump in eleven, and the travel and swing motors in three sections each, so even the internal parts of the larger hydraulic assemblies can be pinpointed.

Because the file is a PDF, it opens on any device – workshop PC, laptop, tablet or phone – and any page can be printed for use on the shop floor. Delivery is instant after payment; there is no shipping and nothing to wait for. A Komatsu PC400-7 excavator parts catalog like this pays for itself the first time it stops a wrong part number going out the door.
