Question 1

Is the Caterpillar C13 engine a reliable engine?

Accepted Answer

The C13 is an inline six-cylinder engine of about 12.5 liters, from the ACERT generation. It has a good reputation on construction equipment when maintained regularly. For used parts, key factors are operating hours, diesel quality, and maintenance history.

Question 2

What is the most reliable diesel engine in the world?

Accepted Answer

No official ranking settles this. Caterpillar engines from the 3306 and 3406 series are often noted for their longevity on machines and trucks. In reality, engine reliability depends first on maintenance, oil quality, air filtration, and working conditions.

Question 3

What is the largest Caterpillar engine?

Accepted Answer

Among machines, one of the largest is the C175-20, a twenty-cylinder engine that powers the 797F mining dump truck. In power generation and marine sectors, Caterpillar offers even larger engines, notably under the MaK brand. These engines are beyond the scope of machines dismantled by Codimatra.

Question 4

Who manufactures Caterpillar engines?

Accepted Answer

Caterpillar designs and manufactures its diesel and gas engines in its own plants. The group also owns several brands: Perkins in Peterborough, UK, which produces several small Cat engines; MaK for medium-speed marine engines; MWM for gas engines; and Solar Turbines for turbines. For a used part, the engine plate remains the only reliable criterion.

Question 5

What is the price of a Caterpillar C18 engine?

Accepted Answer

The price of a C18 depends on its condition, hours, version, and equipment: a complete engine does not cost the same as a single engine part. At Codimatra, engines and engine parts are sold as-is, with prices shown on each listing or by quotation, including transport.

Question 6

Caterpillar engines by cylinder: from C7 to C32

Accepted Answer

The number in Caterpillar C engines indicates approximate displacement in liters: about 7 liters for the C7, 9 for the C9, 12.5 for the C13, 15 for the C15, and 18 for the C18. The C32, a 32-liter V12 engine, powers large mining machines and marine applications. The older 3306 and 3406 engines displace around 10.5 and 14.6 liters.

Question 7

Are Caterpillar 3116, 3126, 3304, and 3412 engines still supported?

Accepted Answer

Yes, these older engines still power many machines in service. We offer their used engine parts depending on availability at dismantling. Provide us with the model found on the plate and the machine’s serial number: our technicians will check availability.

Question 8

Can a used Cat engine be installed on another machine?

Accepted Answer

Sometimes, when two machines share the same engine and arrangement. Compatibility is verified on the engine plate and the machine’s serial number, never on the machine model name alone. Our technicians confirm compatibility before shipping.
