The Komatsu PC300 series operates in a harder-working application than the Komatsu PC200. Buyers of CAT 330 excavators can also consolidate in one shipment. — quarries, large construction sites, and mining operations. This translates directly to faster wear rates and higher spare parts frequency. The PC300's undercarriage, in particular, typically requires replacement every 2,000–3,000 hours in quarry applications versus 4,000+ hours for light earthworks.
Pioneer Mitra's PC300 inventory prioritises the components with the highest export demand: the final drive motor (travel motor assembly) is the most capital-intensive replacement item — a complete assembly is USD 1,400–1,800 FOB India. The main hydraulic pump seal kit (USD 130–170) is the most frequently ordered service item and should be replaced at the first sign of pump case drain increase.
PC300-7 and PC300-8 differ significantly in final drive specification — exactly as the PC200-7 vs PC200-8 differ. Always provide serial number. — the PC300-8 uses a newer-generation 2-speed travel motor. Undercarriage track pitch is identical (154mm) across series, but shoe width options differ. We maintain separate inventory for both series. Also see Komatsu PC200 spare parts for 20-tonne variant and CAT 330 parts for the competing 30-tonne machine.
For fleet operators in Indonesia (a major Komatsu PC300 market), we have established a quarterly supply programme — confirm annual requirements, we pre-stock, and release shipments to Tanjung Priok port as required. Typical JNPT–Jakarta sea freight is 12–16 days. We export to UAE, Kenya, and Nigeria on regular monthly schedules.
PC300-7 (serial 60001+) and PC300-8 (70001+) have different final drive and main pump specifications. PC300-8 uses a Kawasaki-sourced travel motor versus Komatsu-made in PC300-7. Provide serial number — the prefix distinguishes series instantly.
PC300 undercarriage is available in 600mm, 700mm (standard), and 800mm (swamp/soft ground) shoe widths. For quarry and mining, we recommend SBC (Salt Bath Carburised) track links for 30–40% longer service life vs standard. Specify your application.
For a full hydraulic overhaul: main pump seal kit + swing motor seal kit + 2× travel motor seal kit (left + right) ordered as a bundle. Most PC300 operators schedule this at 6,000-hour intervals. Bundle pricing available — contact us with machine serial and hours.
Every Pioneer Mitra shipment includes complete customs-clearance documentation — verified against your payment terms before dispatch.

PC300 operates harder than PC200 — quarry and mining applications mean faster wear. Identify the failure point before ordering: seal kit (USD 85–170) vs full assembly (USD 1,400–2,400).
