Cat C15 Engine

Cat C15 Engines For Sale

The CAT C15 industrial diesel engine is available in ratings from 475-595 bhp at 1800-2100 rpm. Clearly, this engine can produce a significant amount of power. However, it was the C15 that caused Cat to be taken to court by frustrated customers over failures, poor repairs, and financial losses.

Those who purchased this engine in 2007 and 2008 experienced problems concerning 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, which kept Cat from carrying out the proper tests on the Cat C15 Aset engine.

Caterpillar C15 Engine Replacement Options

Sadly, there is an array of issues that can immobilize your engine. Some instances mean that your only option is to replace it. However, sometimes you may just need a few more parts to bring it back to life, or maybe, the engine needs a well-deserved refreshment. Of course, cost, time, and availability will all dictate your decision making so let us inform you of the pros and cons of a new engine from the dealer.

Remanufacturing Process

If someone is unfortunate enough to witness a serious internal engine failure but is fortunate enough to be able to re-use some of their external components, a remanufactured CAT C15 long block is a good way to go. Additionally, a long block is also perfect if your hoping to spend as little as possible or work within a budget.

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

However, it is important to point out that all our C15 Caterpillar remanufactured long blocks are constructed with a mixture of both reman and new parts. We do not recondition or refurbish old engine parts, instead, we completely rebuild the old Cat C15 Aset motor back to OEM specs.

Thorough Cleaning

To avoid the early demise of both parts, and the C15 Caterpillar 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

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

Cylinder Heads

To ensure 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.

Cylinder Blocks

The magnetic particle we use brings to light any defects, therefore the blocks are thoroughly inspected 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 eliminates a cause of engine blow-by. Block surfaces are machined and then inspected to ensure proper finish.

Camshafts

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

Connecting Rods

New bushings are fitted and machined in all bushed rods. Every rod on the CAT C15 is carefully inspected for bend and twist. Connecting rods are cleaned, then machined to OEM specifications and honed to the standard diameter of original equipment for even distribution of stress on the bearings.

New Parts

New parts such as pistons and rings, bearings, gaskets and seals, and liners are all brand new as standard for our C15 Caterpillar long blocks. These new parts ensure dependable performance and reliability throughout the remaining life of your engine. The new parts are a combination of OEM and Aftermarket when available.

Remanufactured Engines Standards

Wearable parts are replaced every time, all C15 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. Replacement parts are either new or requalified. If new, parts are made in the exact same production processes as the original C15 Caterpillar. Testing on all of our Cat C15 Engines for sale is also performed to manufacturer specifications and original production standards to maintain a high level of quality.
