What makes this Komatsu PC300-8 parts book genuinely useful is the way each drawing and its parts list are locked together. The illustration carries a figure number and each component on it carries an index number. Flip to the facing list and that same index number gives you the part number, the part name, the quantity used per machine, and the serial-number window in which that exact part applies. Because Komatsu ran updates through the Y300001-and-up build, the serial-number column is the difference between ordering the right part and ordering one that physically will not fit. The book also documents interchange and supply codes (A1, A2, A3, A4, B1, B2, C1, C2, C3) so you can tell at a glance whether a superseded part is supplied instead, whether something only comes as part of an assembly, or whether it is a semi-finished item that needs additional work before installation.

Beyond the parts data, the layouts are complete for the entire machine. You get the full engine breakdown from cylinder head and cylinder block through the lubricating, fuel, cooling and electrical systems, then the machine-side systems: cooling, fuel, electrical, hydraulics with every control valve and pump detail, frame, cab and operator controls, guards and covers, swing circle, travel motor and final drive, complete undercarriage, and the entire work equipment range with every boom, arm, bucket and breaker adapter option. Optional attachments documented in the book include the WEBASTO coolant heater, fuel refill pump, extreme cold area arrangements, additional actuator circuits, and the full front guard range.

Why This Parts Book Matters

Ordering parts for a Komatsu PC300-8 from memory or from a guess is how wrong components end up on the shelf and how a repair stalls waiting for the right part to arrive. This parts book removes that risk. With exploded views of every assembly, part numbers for every individual component, quantity counts so you know exactly how many you need, and serial-number applicability so you order the version that matches your specific machine build, the ordering process becomes a straight lookup. It is the reference a workshop keeps next to the parts counter and the one an owner keeps on hand for rebuilds, overhauls, hydraulic work, undercarriage replacement, cab and guard repairs, and attachment changes.

What You Can Do With It

• Identify and order the exact engine component for your SAA6D114E-3 serial number range
• Rebuild or overhaul the cylinder head, cylinder block, crankshaft, piston and connecting rod
• Service the lubricating, fuel, cooling and electrical systems with the correct part numbers
• Rebuild the main control valve (2-actuator and 1-actuator) with every inner part broken out
• Overhaul the main piston pump and every hydraulic circuit on the machine
• Replace undercarriage components – idlers, track rollers, carrier rollers, track shoes, track links, guards
• Work on the swing circle, swing machinery, swing motor, swivel joint and travel motor/final drive
• Source cab parts, operator controls, seats, guards, covers, mirrors, counterweight and under covers
• Order work equipment parts for booms, arms, cylinders, buckets and breaker adapters
• Confirm interchange codes so you know whether a newer part number replaces the one on your machine
• Cross-reference any part number in your hand using the numerical index
