Our well-equipped machine shop allows us to control quality and costs in-house. All tolerances are brought within EMD Factory Maintenance Instructions for exact measurements for maximum service life. Tools, gauges and micrometers are calibrated more frequently than AAR requirements to ensure quality results. All work is completed to a documented process that has quality check points at specific sections to ensure that all work completed and signed for by technicians is correct and complete. It is this commitment and attention to detail that make CEECO engines and engine components the best that money can buy in the industry.

Disassembly and Inspection:

• On disassembly, all parts to be reused are carefully inspected to qualify for the rebuild.
• Hot tanking cleaning and magna-flux crack inspections of the block, cylinder heads and other critical components are completed in house.
• Precision laser measurement of the block and crank main bore alignment.
• Check connecting rods for twist and deflection.
• All measurement and inspection results are documented in engine build up sheets and reviewed by shop manager and QA manager for determination of results and necessary repair procedures to ensure a quality product when rebuilding process is complete.

Rebuilding and Assembly:

• Welding and machining of cracks and out of limit wear areas to OEM dimensions as specified in Maintenance Instructions (MI).
• Re-establish cylinder liner pilot bores.
• Re-cut bearing receiver grooves in main bearing caps if line bore was required.
• Re-cut serration's on main bearing caps if line bore was required.
• Rebuild rocker arms and shafts with new bushings, rollers and bearings.
• Blowers are rebuilt if applicable to OEM service limits.
• Cylinder relief valves, rebuilt, with new seals, tips and seats are machined.
• Oil pumps rebuilt with all necessary parts to meet or exceed required (MI) tolerances.
• Water pumps rebuilt with all necessary parts to meet or exceed required (MI) tolerances.
• Injectors rebuilt or new installed if required by customer specification.
• Hand gap piston rings to fit pistons by requirement.
• Regrind intake valves and seats by specification requirements.
• Regrind valves and seats by specification requirements.
• Modifications --idler stubs and oil drain back conversion in front-end sheet and over speed trip housing.

Engine Testing and Horsepower Documentation:

Engines are load-tested in our test cell or in the locomotive. All temperatures, pressures, and engine performance data is recorded on engine test forms for review by shop manager and QA manager. All testing requirements and criteria must be accepted by the QA manager and customer representative prior to final acceptance.
