Technical specifications
The figures below are manufacturer reference data for the versions identified. Final output, dimensions, controls and emissions equipment depend on the engine build and application.
| Specification | Details |
|---|---|
| Engine model in OEM references | SA6D140E-2 |
| Cylinders | 6 |
| Bore | 140 mm |
| Stroke | 165 mm |
| Displacement | 15.24 L |
| Cycle / cooling | 4-stroke; water cooled |
| Fuel / induction | Direct-injection diesel; turbocharged with aftercooler |
| DCA-400SSK reference engine rating | 478 HP at 1,800 rpm (generator OEM reference only) |
| DCA-400SSK reference frequency | 60 Hz at 1,800 rpm; applies to the reference genset, not the loose engine |
Technical details
- Multiquip documents SA6D140E-2 powering its DCA-400SSK generator package.
- The reference genset uses an electronic governor for tighter frequency regulation than the mechanical-governor arrangement described in the manual.
- The same engine model is also cataloged by Komatsu for a D155A-5 dozer, showing that the engine model alone does not define external package fit.
Applications & fitment
Documented application references
- Multiquip DCA-400SSK portable generator is a documented SA6D140E-2 installation.
Application examples identify documented uses of the engine family. Confirm fitment against the machine and engine serial numbers before ordering.
Confirm your engine match
- Match the governor, flywheel coupling, cooling package, mounts and controls to the generator model and serial number.
- The DCA-400SSK power and frequency figures are examples from a complete generator set; the engine assembly rating depends on its own arrangement.
For fitment checks, availability or a quote, email info@nyengines.com with your engine data-plate photo, machine details and required assembly scope.
Buyer guide
- Multiquip rates its DCA-400SSK generator at 60 Hz with the SA6D140E-2 running at 1,800 rpm. Confirm the destination set's required frequency and governing arrangement.
- The DCA-400SSK parts list changes its SA6D140E-2 engine assembly part number at generator serial 3701677; match the set serial and engine part number before replacement.
Buying questions
Does the engine assembly itself supply the DCA-400SSK's 400 kVA output?
No. The 400 kVA figure is the electrical rating of the complete Multiquip generator set. Its engine is listed separately at 478 HP at 1,800 rpm; verify the supplied engine arrangement and alternator package.
Does the cited generator manual confirm 50 Hz operation?
No. Its documented DCA-400SSK reference is 60 Hz at 1,800 rpm. A 50 Hz installation needs its own engine and generator configuration check.
