Confirm Before You Order

Step 1: Locate the engine nameplate on your existing engine. Note the model number, CPL number, and serial number.
Step 2 : Cross-reference against the standard identifiers: CPL 8671 · Configuration No. L563000CX03 · Datasheet FR92213. If these match, you have confirmed the correct replacement.
Step 3 : Send us a photo of your nameplate before ordering. Our team will verify the match and confirm in writing within 24 hours. Free of charge.

Cummins 6LTAA8.9-C325 Specifications

Know Your Variant Before Ordering

The 6LTAA8.9 is a product family. Five variants share the same block but differ in power output, fuel system, and tuning. Before ordering, verify your data plate reads exactly 6LTAA8.9-C325. Ordering the wrong variant will result in a mismatch in fuel system calibration and power output.

Not sure which variant your machine uses? Send us your engine naemplate photo and we will identify the correct model within 24 hours.

Build Quality

The 6LTAA8.9-C325 is built to Cummins' global heavy industrial standard. Four design features define its durability in the field:

Replaceable wet cylinder liners : individual cylinders can be re-sleeved at overhaul without machining the block, reducing major repair cost and downtime.
Two-piece articulated steel pistons: forged steel crown for heat and pressure resistance, aluminum skirt for reduced reciprocating mass. Standard across Cummins' heavy industrial engine range.
Targeted piston cooling :oil jets spray directly onto the underside of each piston crown, preventing thermal overload during sustained full-load operation.
24-valve cylinder head with central injector : ensures even fuel distribution and complete combustion across all operating conditions, maintaining consistent output and minimizing deposit buildup over the engine's service life.

Brand & Authenticity

Dongfeng Cummins Engine Co., Ltd. (DCEC) is a 50/50 joint venture between Dongfeng Motor Corporation and Cummins Inc. USA, established in 1986 in Xiangyang, China. The 6LTAA8.9-C325 is a genuine Cummins engine manufactured under Cummins' engineering specifications and quality control — not a licensed copy, not an aftermarket replica.

FAQ

Q1: How do I confirm this is the correct replacement for my machine?
Check your existing engine's data plate. If the model reads 6LTAA8.9-C325 and the CPL reads 8671, the engine we supply is a direct replacement. If in doubt, send us a photo of the data plate and we will confirm in writing within 24 hours.

Q2: Can I send my old engine nameplate photo before ordering?
Yes, and we strongly recommend it. We will cross-reference it against our inventory, confirm the exact configuration match, and advise on any accessories that need to be transferred from the old engine. Free of charge, within 24 hours.

Q3: Will it fit without modifications?
For machines where the 6LTAA8.9-C325 is the factory-installed engine, yes. The replacement mounts directly to existing engine mounts, the bell housing bolt pattern matches, and all accessory interfaces are identical. Standard swap procedure only — no machining, no adaptor plates.

Q4: Why do different websites list different specs for this engine?
Three reasons: weight varies by configuration (bare engine vs. with flywheel vs. with alternator); fuel pump brand differs across production batches (Bosch P7100 vs. Weifu PW2000); and compression ratio figures reflect different calibration revisions. We confirm the exact configuration of every unit before shipment and provide data plate photos as part of the pre-shipment package.

Q5: Is this a genuine Cummins engine or a Chinese copy?
DCEC is an official Cummins joint venture with Cummins USA holding 50% equity since 1986. These are genuine Cummins engines — CPL 8671 is traceable through Cummins' global systems. We do not supply remanufactured or replica engines.

Q6: My machine operates above 2000m. Does that affect the replacement?
Your existing machine has already been running at altitude, so the original engine was configured accordingly. When you send us your data plate photo, mention your operating altitude and we will confirm whether a standard unit or a specific high-altitude configuration is required.

Q7: What warranty is included?
1 year or 1500 hours, whichever comes first, covering manufacturing defects in materials and workmanship. Does not cover damage from improper installation, incorrect fluids, or operation beyond rated parameters.

Q8: What spare parts are available?
We stock genuine DCEC Cummins parts including injection pump components, turbocharger, cylinder liners, piston and ring sets, bearings, gasket sets, cooling system components, and complete overhaul kits — all referenced against the genuine parts catalog .

Q9: Can you supply a complete power pack?
Yes. Power packs are available with radiator, air filter, exhaust muffler, engine monitoring panel, and skid frame. Pump drive configurations also available. Specify your requirements at the time of inquiry.

Q10: What are the payment and shipping terms?
Payment: T/T (30% deposit, 70% before shipment) or L/C.
Shipping: FOB Shanghai, CIF destination, or EXW. Full export documentation provided as standard. Third-party inspection (SGS, BV) available at buyer's cost.

Packaging & Shipping

Each Cummins engine and parts  is inspected carefully before shipment, including serial number and appearance verification. It is then packed in reinforced, steel-framed wooden crates with moisture-proof and orientation labels. Key components such as ECM modules and Cummins injectors are packed separately in shock-proof containers and include export certificates.

We cooperate with leading international freight forwarders, supporting CIF, FOB, and DDP trade terms. Customers in Africa and Southeast Asia usually choose LCL or FCL sea shipment, with a typical delivery cycle of 18–25 days.
