Cat C13 Engine

Cat C13 Engines For Sale

CAT C13 EngineThe C13 Caterpillar industrial diesel engine is available in ratings ranging from 287-288 bkW (385-520 bhp) at 1800 – 2100 rpm. The Caterpillar C13 engine boasts an impressive 520 bhp. However, it was the C13 that caused Cat to be sued by dissatisfied customers over failures, poor repairs, and financial losses.

Those who purchased this engine in 2007 and 2008 experienced problems relating to the diesel particulate filter regeneration system such as clogged injectors, sensor defects, and fuel line issues. However, this was partly due to the EPA enforcing strict emission standards over a fairly short period of time. Due to this, Cat could not carry out the proper tests on the engine.

Remanufacturing Process

If someone is unlucky enough to witness a serious internal engine failure but lucky enough to be able to re-use some of their external components…a remanufactured C13 Caterpillar long block is a good way to go. In addition, a long block is also perfect if your hoping to spend as little as possible.

To accomplish this, our team of experienced machinists and engine builders will first do a full core tear down, cleaning, inspection, and machining of the engine before it leaves our facility, guaranteeing every engine is in good condition each and every time.

However, it is crucial to point out that all our C13 Caterpillar remanufactured long blocks are assembled with a mixture of both reman and new parts. We do not recondition or refurbish old engine parts, instead, we entirely rebuild the old C13 Caterpillar motor back to OEM specs.


To avoid the early termination of both parts and the Caterpillar C13 engine itself, we remove all impurities by stripping the blocks, heads, rods, and camshafts which are then thoroughly cleaned in a chemical jet wash or hot tank.


Crankshafts are precision machined to exact tolerances, polished & magnafluxed, then thoroughly inspected by our quality control team.


To guarantee a proper sealing surface with the block, and to achieve a finish compatible with modern gasket materials, the heads are resurfaced. Valve height is mic-d and every head is vacuum tested to assure correct valve seating.


We use magnetic particle to inspect blocks that carefully examined for any cracks or damage. To ensure the avoidance of cylinder head distortion after the head is bolted and torqued to the block, the cylinder heads are bored and honed to precise tolerances. In turn, this drastically reduces a cause of engine blow-by. Block surfaces are machined and then inspected to achieve a proper finish.


Camshafts are inspected and precisely machined to provide correct lift. Lobs are measured with a micrometer to make sure OEM tolerances are met.


Fresh bushings are fitted and machined in all bushed rods. Every rod is carefully inspected for bend and twist. Connecting rods are cleaned, then machined to OEM specs and honed to the usual diameter of original equipment for even distribution of strain on the bearings.


Pistons and rings, bearings, gaskets and seals, and liners are all brand new as standard for our C13 Caterpillar long blocks. These new parts ensure dependable performance and reliability throughout the life of your engine. The new parts are a mixture of both OEM and Aftermarket when available.

In addition, wearable parts are replaced every time, all C13 Caterpillar core material is then inspected and examined against the original specifications to ensure correct dimensional tolerances. After all, the aim of remanufacturing is to make it as close to new as possible. Alternate parts are either new or requalified. If new, the parts are produced in the exact same manufacturing process as the original C13 Caterpillar. Testing on all of our Cat C12 Engines for sale is performed to manufacturer specifications and original production standards.
