Komatsu PC300-8 PC300LC-8 Hydraulic Excavator Parts Book LEPBP30802 – Full Illustrated Parts Catalog PDF

Description

Every nut, bolt, hose, seal, cylinder, pump and bracket on the Komatsu PC300-8 and PC300LC-8 is listed somewhere in this book — and this is that book. The Komatsu PC300-8 PC300LC-8 Parts Book LEPBP30802 is the complete illustrated parts catalog for both the standard-crawler PC300-8 and the long-crawler PC300LC-8 hydraulic excavators, covering machines from serial number J30001 and up and the SAA6D114E-3 diesel engine from engine number 26854260 upward. Each figure is an exploded drawing with callout numbers that map directly to a table of Komatsu part numbers, descriptions, quantities and the serial-number breakpoints that tell you which variant a part belongs to. Nothing here is generic — every page was drawn around these two exact excavator models.

Working through the catalog from front to back gives a technician a fully indexed map of the machine — from the SAA6D114E-3 long block and its bolt-on accessories, through the cooling, fuel and electrical systems, across the hydraulic main valve, main pump and every hose and tube that connects them, down through the revolving frame, swing circle, track frames and undercarriage, and out to the boom, arm, bucket cylinders and every cutting edge attachment. Because the tables preserve the original Komatsu part numbers and serial-number splits, you can identify the exact component that matches your serial-number range without guessing at a parts-counter cross-reference. The index pages at the back of the book link part numbers and figure numbers, so you can jump straight to the illustration that contains the part you’re looking for.

Who This Komatsu PC300-8 PC300LC-8 Parts Book Is For

This is not a workshop manual and it does not contain repair procedures — it is a genuine illustrated parts catalog, built for owners, fleet mechanics, independent repair shops and parts departments who need the correct Komatsu part number for a specific assembly before ordering or before pulling a component apart. It suits anyone running a PC300-8 or PC300LC-8 on a job site, rebuilding an SAA6D114E-3 after a failure, replacing a hydraulic hose or pump on the bench, or cross-checking a rebuild kit before it ships. Whenever a machine is stopped, the fastest route to getting it running again usually starts with the right number in hand — and this catalog exists for exactly that.
