Why Remanufactured? Four Good Reasons:
Lower Cost

One of the biggest factors in choosing a remanufactured engine is cost. Remanufactured engines cost up to 50 percent less than a new Tier 4 Final engine, not including associated engineering costs, and offers even greater savings over the purchase of a new piece of equipment. Maintenance on some new Tier 4 Final engines can be costly as well. In addition to being more complex to service, additional costs for after treatment cleaning and DEF fluid can add up quickly.

Less Downtime

Opting to replace your existing engine with a new one typically requires significant engineering time that can render rental equipment out of service for months. The integration and testing process also takes significantly longer with a new Tier 4 Final engine than with remanufactured engines.

Increased Equipment Resale Value

There are two main factors currently making it difficult to sell Tier 4 Final-powered equipment in lesser regulated countries: serviceability and fuel availability. The lack of established service programs for the new technology makes supporting the product difficult. This coupled with high product costs, have companies shying away from Tier 4 Final powered equipment. In addition, many lesser regulated countries don’t have high availability for ultra-low sulphur diesel fuel, which is required by Tier 4 Final engines to operate effectively. Without it, the diesel particulate filter can clog rapidly and cause significant operation issues.


Purchasing a remanufactured engine keeps an old engine core and many usable components out of a landfill, which can greatly reduce the impact on the environment. According to Perkins Pacific’s Andy Machin, approximately 73 percent of the old engine can be salvaged during the remanufacturing process saving millions of pounds of waste out of landfills. New engine production requires all new materials, substantial amounts of energy for the production process and additional transportation costs. By utilizing recycled components, a remanufactured engine typically uses about 80 percent less energy than new engine production, making it a much greener option. For rental fleet owners, reman offers the opportunity to expand their sustainability practices while saving money.
