The Cummins QSB6.7-C260 is a 6.7L, 6-cylinder industrial diesel engine delivering 260 HP / 194 kW at 2,200 RPM and 990 N·m peak torque at 1,500 RPM. It is a high-output QSB6.7 series engine designed for heavy-duty construction machinery, mining support equipment, hydraulic equipment and industrial power applications that require strong low-RPM torque and stable electronic control.
Powered by a High Pressure Common Rail fuel system, DCEC ECM electronic control, Holset turbocharger and air-to-air intercooling, the QSB6.7-C260 is suitable for excavators, cranes, loaders, bulldozers, drill rigs, road rollers and other hydraulic-intensive equipment. It meets Tier 3 / EU Stage IIIA / NS III emission standards for international project use.
For replacement or project procurement, ZEB Power helps confirm the correct engine configuration by ESN, CPL code, configuration code, machine model and application requirements before quotation. This helps reduce the risk of wrong engine selection, installation delays and incompatible parts.

QSB6.7 Series Comparison
All QSB6.7 variants share the same 6.7L, 107 mm × 124 mm, 6-cylinder in-line architecture. Selection is mainly determined by required power output, torque demand, fuel system, emission tier and approved equipment configuration.
| Model | Rated Power | Peak Torque | Fuel System | Aspiration |
|---|---|---|---|---|
| QSB6.7-C130 | 133 HP @ 2200 RPM | 580 N·m @ 1400 RPM | HPCR | Turbo + Air-Air IC |
| QSB6.7-C133 | 133 HP @ 2200 RPM | 584 N·m @ 1450 RPM | Bosch Electronic | Turbo + CAC |
| QSB6.7-C170 | 170 HP @ 2000 RPM | 656 N·m @ 1400 RPM | Bosch Electronic | Turbo + CAC |
| QSB6.7-C190 | 190 HP @ 2200 RPM | 931 N·m @ 1400 RPM | Bosch Electronic | Turbo + CAC |
| QSB6.7-C220 | 220 HP @ 2200 RPM | 949 N·m @ 1500 RPM | Bosch Electronic | Turbo + CAC |
| QSB6.7-C260 | 260 HP @ 2200 RPM | 990 N·m @ 1500 RPM | HPCR | Turbo + Air-Air IC |
The QSB6.7-C260 combines HPCR fuel system, air-air intercooling and 260 HP output at 2,200 RPM. If the equipment requires less than 220 HP, the QSB6.7-C190 or QSB6.7-C220 with Bosch Electronic system may be considered, but any substitution should be confirmed against the equipment OEM approved engine list.
Replacement Compatibility
The QSB6.7-C260 can be considered as a replacement candidate for earlier QSB6.7 series engines sharing the same 107 mm × 124 mm bore/stroke and 6.7L displacement. However, replacement should not be confirmed by displacement or model series alone. Mounting, interface, ECM, starting voltage and emission requirements must be checked before ordering.
| Check Item | Confirmation Requirement |
|---|---|
| Dimensional Check | Engine envelope 1111 × 716 × 960 mm — confirm chassis clearance and mount point alignment |
| Interface Check | Confirm SAE flywheel housing and bell housing ratings against the transmission or hydraulic pump interface |
| Electrical Check | Confirm ECM wiring harness connector compatibility; 24V systems require 24V/750A starter, 12V systems require 12V/500A starter |
| Emission Check | Tier 3 / EU Stage IIIA / NS III; confirm destination country in-use emission regulations before replacement |
| CPL Verification | Provide existing ESN or nameplate CPL code for exact configuration matching |
For accurate matching, please provide the engine serial number, CPL code, machine brand and model, current engine photos and any required configuration information such as starting voltage, emission tier or auxiliary systems.

Frequently Asked Questions
What is the difference between QSB6.7-C260 and QSB6.7-C260-30?
QSB6.7-C260 is the main model designation, while QSB6.7-C260-30 may be used by some suppliers to describe a specific configuration batch. Core specifications such as 260 HP, 990 N·m and 6.7L displacement remain the key matching points. The configuration code D313013CX03 and CPL should be confirmed at order stage.
Is the QSB6.7-C260 a direct replacement for my existing QSB6.7 engine?
It may be suitable if the block architecture, ECM calibration, fuel system, mounting interface, starter voltage and emission requirement match. Please provide ESN or CPL code before ordering for a compatibility check.
What emission standard does the QSB6.7-C260 meet?
The QSB6.7-C260 meets Tier 3 / EU Stage IIIA / China NS III. If the destination market requires Stage IV or Stage V compliance, the required engine variant should be confirmed before purchase.
Can this engine start in cold weather without auxiliary equipment?
The listed minimum starting temperature is –12 °C without auxiliary aid and –24 °C with auxiliary pre-heating support. For cold-region projects, the complete starting system and site conditions should be confirmed before ordering.
What fuel system does the QSB6.7-C260 use?
The QSB6.7-C260 uses a High Pressure Common Rail fuel system with DCEC ECM control. Lower-output QSB6.7 variants may use Bosch Electronic systems, so fuel system components are not automatically interchangeable across variants.
How long does delivery take?
Standard lead time is 15 working days from order confirmation. FOB Shenzhen is available, and CIF or CNF terms can also be arranged depending on the destination and order requirements.
Are QSB6.7-C260 spare parts available separately?
Yes. Engine parts for filters, HPCR fuel system, turbocharger, overhaul kits, seals, gaskets, ECM, sensors and harness connectors can be supplied. Please provide ESN or CPL code for accurate part number matching.
