A Model Line That Changed Pump Platforms Mid-Way
The PC300, a 30-tonne class excavator, is a genuine case where getting the exact generation right matters — the PC300-6 runs a Komatsu HPV132, while the PC300-7 and PC300-8 moved to the newer HPV140. These aren't interchangeable despite belonging to the same broad model line. This page covers exact specs and part references for both.
Komatsu's 708 series part numbering identifies pump size by suffix — "-2H" marks PC300/PC350-size pumps, distinct from the "-2L" used on the smaller PC200/PC210 class and "-2G" on the larger PC400 class. Within the PC300 line itself, the platform evolved: the PC300-6 generation used the HPV132, while the PC300-7 and PC300-8 generations moved to the HPV140 — a genuine pump redesign, not just a part-number refresh. Confirming your exact generation before ordering avoids a costly mismatch.
| Generation | Pump Model | Part Number Reference | Equipment Class |
|---|---|---|---|
| PC300-6 | HPV132 | 708-2H-00330 / 708-2H-00181 | 30-tonne |
| PC300-7 / PC300-8 | HPV140 | 708-2H-00131 / 708-2G-00024 / 708-2G-00700 | 30-tonne |
