Cummins Engine 6BTAA5.9-C205 For Constrcution

The 6BTAA5.9-C205 is the highest-output mechanical variant in the DCEC 6BT5.9 industrial series — a 5.9-litre, six-cylinder inline engine producing 153 kW (205 HP) at 2200 RPM with a peak torque of 870 N.m at 1400 RPM.
Aspiration is turbocharged with air-air intercooling. The fuel system uses a BYC P7108 mechanical injection pump with RSV governor; Weifu PW2000 pump is found on some production batches — confirm the fitted pump via engine nameplate before ordering pump-specific parts.
Typical applications include heavy construction machinery, large-capacity compressors, drilling rigs, and high-demand pump drives where continuous-duty output is required. Rating type is Continuous; emission standard is N/A (no after-treatment system, not Stage II designated).

Technical Specifications

Note: Fuel pump configuration (BYC P7108 / Weifu PW2000) varies by production batch. Verify via engine nameplate or CPL 3536 documentation before ordering injection system components.

Series Comparison: 6BT5.9 Industrial Variants

6BTAA5.9-C125-Ⅱ aspiration is listed as Water-Air Intercooled in source documentation, which is atypical for a double-A designation. Verify via engine nameplate if replacing this variant.
All -Ⅱ suffix models carry Euro Stage II certification. The C205 and C180 carry no emission designation and are not fitted with after-treatment systems.
Selection guidance: The C205 is the only variant in this series delivering continuous-duty output above 132 kW with mechanical injection. If Euro Stage II compliance is required, the 6BTA5.9-C180-Ⅱ (132 kW) is the highest-rated certified alternative.

Replacement Compatibility

The 6BTAA5.9-C205 shares the same block architecture (5.9 L, 102 × 120 mm bore and stroke) with all 6BT5.9 series variants. Physical envelope dimensions are consistent across the series, making same-series engine replacement viable in most existing installations without structural modification.

CPL 3536 is the definitive compatibility identifier for this variant. When replacing an existing engine, match the CPL from the original engine nameplate — not the model name alone — to confirm that injection pump specification, governor calibration, and power curve are aligned with your application requirements.

SAE flywheel housing interface should be verified against the original application datasheet or Cummins QuickServe Online (CPL 3536) before mounting to an existing drivetrain. Submit your ESN at inquiry stage and we will cross-reference fitment before confirming the order.

Parts & Service

The 6BT5.9 is a long-production platform with broad global parts availability. Core service items for the C205 variant include:

· Overhaul kits (in-frame and complete) — specify CPL 3536 when ordering to ensure correct piston, liner, and ring configuration
· Fuel injection pump repair kits and calibration components specific to BYC P7108 / RSV governor
· Turbocharger assembly and air-air intercooler core replacement
· Oil filter, fuel filter, air filter — standard 6BT5.9 series fitment
· Cylinder head gasket set, piston rings, liner set — standard 6BT5.9 architecture

All parts orders require CPL code (3536) or ESN for fitment confirmation. High-turnover service items are held in stock. Contact us for a parts compatibility list referenced to your engine serial number.

FAQ

Q1: What is the CPL code for the 6BTAA5.9-C205?

A: The CPL code is 3536. Use this code when ordering overhaul kits, injection pump components, or any CPL-specific parts to ensure correct fitment.

Q2: Which fuel injection pump does the 6BTAA5.9-C205 use?

A: The standard configuration uses a BYC P7108 mechanical injection pump with RSV governor; some production batches are fitted with a Weifu PW2000 pump. Confirm the fitted pump via engine nameplate before ordering pump-specific parts or repair kits.

Q3: Can the 6BTAA5.9-C205 directly replace a 6BTA5.9-C180-Ⅱ or another 6BT5.9 variant?

A: Physical block and mounting dimensions are consistent across the 6BT5.9 series, so direct installation is generally possible. Injection pump type, governor calibration, and rated output differ between variants — submit the original CPL and ESN for a compatibility review before proceeding.

Q4: What is the difference between the 6BTA and 6BTAA designations in this series?

A: Single-A (6BTA) indicates turbocharged with water-air intercooling; double-A (6BTAA) indicates turbocharged with air-air intercooling. These configurations use different intercooler cores and cooling circuit layouts and are not interchangeable at the intercooler assembly level.

Q5: Is the 6BTAA5.9-C205 emissions-certified?

A: This variant carries an N/A emission rating — it is a mechanically governed engine with no integrated after-treatment system, and is not designated for markets requiring Euro Stage II or higher compliance. Contact us if you require a Stage II-certified 6BT5.9 variant; the 6BTA5.9-C180-Ⅱ is the highest-output certified option in this series.

Q6: What is the standard overhaul interval for the 6BT5.9-C205 under continuous duty?

A: Overhaul intervals are application- and load-dependent; consult the DCEC Operation and Maintenance Manual or Cummins QuickServe Online for CPL 3536 for the applicable schedule. Submit your ESN for a service interval reference tied to your specific unit.

Q7: Can parts be ordered alongside the engine?

A: Yes — in-stock inventory covers high-turnover 6BT5.9 items including overhaul kits, filters, and fuel system components. Parts orders require CPL 3536 or ESN for fitment confirmation.
