Used Diesel Engines and Used Natural Gas Engines

Inventory If you have found this section of our website, it is highly likely you are trying to solve a problem. As a remanufacturer of diesel engines and engine components, Capital Reman is naturally inclined to recommend remanufacturing over used. That is not simply because we have a particular bias, but because used engines and remanufactured engines is like comparing apples and oranges.

Capital Reman produces 30-40 remanufactured long blocks each month. That means we have the specifications or birth certificate for every engine and/or component we remanufacture and produce. Because we control the quality in our facility we are able to stand behind our products and services. There are very few guarantees in life or business, and there are even less when it comes to used engines. We have sold our share of used engines over the years because a customer has decided or been told by someone, “this is what you need”. Unfortunately, that is not always the case. Having heard all the horror stories, the data we have gathered over the years indicates used engines often equals old problems, and that is counterintuitive to what Capital Reman stands for as a company and what customers are trying to accomplish.

CAT 3306 BlockWhat buyers often fail to consider is the cost of a used engine is nearly the same or more expensive than a remanufactured engine. Sometimes it can be twice or three times as expensive because a buyer bought someone else’s problem(s).

We are not saying that every used engine is a bad engine. That is not true, but it is our experience in having sold used engines over time and being a remanufacturer, that the most cost effective and reliable long term option is a remanufactured engine or component. We have received the phone calls from people who simply want to “patch” something together and drop in any used engine in order to sell their truck or equipment. Now consider the person or business on the other side of that transaction when they realize they bought a problem and need an engine.

Our greatest advice when it comes to used engines is to do your homework. Know what you are buying, know where it came from, who it came from, how it was maintained, what dyno analysis may exist, in what conditions it was operated, and know what warranty options exist, if any.

As a remanufacturer, Capital Reman strongly believes in the remanufactured products and services we provide, however also acknowledge there are some instances where a used engine is either necessary or may make the most sense for a given circumstance. As a consumer, if you find yourself in that situation please don’t hesitate to call us. We will take a consultative approach in helping you navigate these waters to help you achieve a thoughtful and well planned decision when it comes to your engine or engine component needs. In addition to reman engines our subsidary company, Big Bear Engine Co. also supplies new surlpus and used Cummins 4BT/6BT engines.
