Product Overview


EconoLife Power Assemblies for EMD Model 645E and 645E3 Engines


With a focus on power, performance and innovation, Progress Rail, through its iconic EMD brand, has been a premier provider of diesel-electric locomotive technology for nearly 100 years. EMD locomotives comprise a majority of the active worldwide fleet, leading the company to develop a variety of unique OEM aftermarket (replacement) parts. An example of Progress Rail’s ongoing product support are the new EconoLife™ Power Assemblies.

This economical power assembly solution is intended for older locomotives, used in switch duty service, that are equipped with EMD 645E roots-blown or 645E3 turbocharged engines. In such light duty applications, where maintenance costs are often the primary concern, EconoLife power assemblies are an ideal option versus standard and premium components.

EconoLife power assemblies are offered in standard fork, blade, and partial pack configurations.

EconoLife power assemblies are not emissions certified and can ONLY be used on engines not currently labeled as EPA Tier 0 or Tier 0+ compliant. Many locomotives equipped with EMD 645E or 645E3 engines are exempt from those emissions requirements as a result of the locomotive age or other EPA criteria.

EconoLife 645E power assemblies with a 14.5:1 compression ratio and rocking pin configuration may be used as an alternative to 645E3 power assemblies with a 14.5:1 compression ratio and straight pin configuration

EconoLife power assemblies are primarily intended for running repair of individual failures. In certain cases, multiple power assemblies may be replaced on non-exempt engines.
