Buyer guide
- Komatsu rates the SAA12V140E-3 at 895 kW ISO 14396 and 1,900 rpm in HD785-7, but 728 kW and 1,800 rpm in PC2000-8. Match the application calibration.
- Komatsu packages the PC2000-8 engine with radiator, oil cooler, hydraulic pumps and PTO in a power module. Confirm which of these are actually included with a replacement engine assembly.
- The HD785-7 reference uses a 24 V, 90 A alternator and two 7.5 kW starting motors; electrical equipment on the offered arrangement must be checked separately.
Buying questions
Does the HD785-7 engine rating also apply to a PC2000-8?
No. The cited Komatsu brochures give 895 kW at 1,900 rpm for HD785-7 and 728 kW at 1,800 rpm for PC2000-8, each for its own installation.
Is a PC2000-8 power module included with an engine assembly?
Do not assume so. Komatsu describes its PC2000-8 power module as combining the engine with the radiator, oil cooler, hydraulic pumps and PTO. Confirm the seller's included-component list.
