The scope of this Komatsu PC300-8 parts catalog is the entire machine split into its working systems. For a technician or parts manager this means every fastener, seal, hose, gasket, wear part and major casting is traced back to the correct Komatsu reference number without relying on memory or a distributor’s database query. The exploded figures show how each group assembles, so you can also plan a strip-down or rebuild correctly the first time.

IMAGES PREVIEW

Why This Parts Book Matters for PC300SE-8 and PC300LCSE-8 Owners

A hydraulic excavator this size spends its working life under load, and the parts that fail are usually the ones you can least afford to order twice. A wrong seal kit, a wrong pump section, a mismatched undercarriage component or a wrong bucket tooth adapter stops the machine for days. The PC300SE-8 PC300LCSE-8 Parts Book removes that risk by giving you the exact numerical reference at every level, from a single O-ring all the way to a complete hydraulic pump assembly.

Because the listing is grouped by assembly rather than alphabetically, you can look up a whole sub-assembly – for example the main valve connecting parts or the travel motor sections – and see at a glance which pieces are supplied individually, which are sold as a service kit, and which are only available complete. That is exactly what the notes column in the diagrams tells you, using the same interchange and discontinued-part codes a Komatsu distributor applies when you place an order.
