Product Advantages

The D2-generation swap on a 320D2/323D2 starts and ends with the engine tag: C7.1 ACERT, common rail, 7.1 liters - a different engine from the C7 and C6.4 decks of earlier machines. A new complete assembly keeps the 20-33-ton deck running without an in-frame gamble, and the ENGINE AR 417-3389 reference gives both sides a single number to quote.

ENGINE AR 417-3389 gives both sides one number to quote
Clear C7.1 vs C7/C6.4 generation boundary
Reliable replacement for the 320D2/323D2 deck
One supplier, one shipment, one warranty line

Frequently Asked Questions

Q1: Which machine is this C7.1 engine used on?

The C7.1 ACERT powers the CAT D2-generation excavator line: 320D2/320D2L, 323D2/323D2L, 326D2/326D2L, 329D2/329D2L and 330D2/330D2L. Confirm machine serial and the original engine dataplate before ordering.

Q2: What are the specifications of this engine?

It is a CAT 7.1-liter inline-6, 4-stroke diesel with 105 x 135 mm bore and stroke and electronic high-pressure common rail fuel. The 320D2 build (AR 417-3389) is rated 112 kW (150 hp) at 1,800 rpm, with 118 kW reported on the 323D2L.

Q3: What is the difference between C7.1, C7 and C6.4?

Different engines on different generations. The C7.1 ACERT is the 7.1-liter common-rail engine of the 320D2/323D2 generation; the earlier 320D/323D decks run C7 ACERT or C6.4 depending on model. Never cross-fit - the dataplate decides.

Q4: Is this a genuine new engine?

Yes, new complete assembly, never run, with provenance documentation on request. Remanufactured and used original options are available separately.

Q5: What are the main assembly reference numbers?

417-3389 (ENGINE AR-PRIMARY) is the core reference for the 320D2 C7.1. 542-4983 covers the 326D2/329D2/330D2L deck and 452-0960 the 330D2, with 451-1222/383-3581 also circulating as assembly refs. Always verify against the dataplate.

Q6: How can I confirm the engine matches my machine?

Send us your machine model, serial number and the engine dataplate photo. We verify the assembly number and confirm scope before order confirmation. Each engine undergoes assembly inspection and running verification before packing, and export-standard steel frame/wooden case packaging is used to prevent damage in transit.
