c13
Complete C13 ACERT engine assembly built on a 130 mm bore and 157 mm stroke, displacing 12.5 litres (762.8 cu in). Rated 287 kW / 385 bhp at 2100 rpm on the continuous curve, with 1,760 N·m available at 1400 rpm. The maker sheet records arrangement 2413804, a compression ratio of 17.3 to 1, 939 kg dry weight, and compliance with EPA Tier 3 and EU Stage IIIA. Fuel delivery is by MEUI under ADEM A4 control — this is not a common rail system, despite what many trade headings claim.
| Product Name | Complete Engine Assembly |
|---|---|
| Engine Model | C13 ACERT (C13B is a later build) |
| Configuration | Inline six, four stroke, liquid cooled |
| Displacement | 12.5 L / 762.8 cu in |
| Bore and Stroke | 130 mm by 157 mm |
| Aspiration | Turbocharged, air-to-air aftercooled |
| Compression Ratio | 17.3 to 1 |
| Fuel System | MEUI injection, ACERT, ADEM A4 control |
| Rated Output | 287 kW / 385 bhp at 2100 rpm, continuous |
| Torque | 1306 N·m at 2100 rpm, 1760 N·m at 1400 rpm |
| Arrangement Number | 2413804, feature code C13DI00 |
| Emissions | EPA Tier 3, EU Stage IIIA |
| Dry Weight | 939 kg / 2070 lb |
| Envelope | 1202.6 by 1011.1 by 1185.5 mm |
| Rotation | Counterclockwise viewed from the flywheel end |
| Maker Arrangement | 2413804 is printed on the maker sheet for the 287 kW continuous build, and it does not appear in most trade headings. |

| Trade Assembly Numbers | 423-3922, 291-9259, 3427863, 417-2601, 487-6161 and 467-2584 all circulate against this engine. |
| Reman Prefixes | 20R-5388 and 20R-2862 mark exchange units; 6V-3100 uses a legacy numbering style that predates this family. |
| Torque Across the Curve | 1306 N·m at rated speed climbing to 1760 N·m at 1400 rpm — a machine complaint about lugging is answered by the curve rather than by the peak figure. |
Turbocharger 518-0435, injector 249-0713 (also supplied as 10R-3262), cylinder head, gasket set, piston and liner kit, bearings, oil pump, water pump, and ECM.
Q1: Why does the same C13 show 385 hp in one place and 520 in another?
Because the rating family is chosen for the duty. This sheet describes a continuous application where the engine may sit at full power without interruption, and continuous ratings are deliberately conservative; other applications allow higher output because the load cycles. Both figures are honest, and neither is useful until the machine and the duty are named.
Q2: Is this engine common rail?
It is not. Fuel is delivered by mechanically actuated electronic unit injectors, with timing and quantity decided by the control module rather than by rail pressure. That matters at the parts counter because rail components and MEUI components belong to separate families, and a mixed order produces a machine that will not start.
Q3: What should I photograph before ordering a replacement?
The arrangement plate, the injection pump side of the block, and the bell housing face. Those three images settle the arrangement number, the governor, and the flywheel housing in one exchange — faster than three rounds of questions, and it removes most of the risk of shipping an engine that fits the machine but not the harness.
Q4: Which arrangement number applies here?
2413804, listed with feature code C13DI00.
Q5: What does the engine weigh?
939 kg dry, measuring 1202.6 by 1011.1 by 1185.5 mm.
Q6: Which emission stage does it meet?
EPA Tier 3 and EU Stage IIIA.
