Standard Procedures for Remanufactured Engines

Diesel Specialists, LLC. has over 35 years' experience rebuilding Cummins engines

, following the strictest of remanufacturing procedures. First, engine cores are completely disassembled and all parts are cleaned in a chemical vat. Engine parts are then dispersed to our specialized workshops for inspection and remanufacturing.

Thorough Inspection of Cummins Cylinder Blocks

  • Cylinder blocks are checked for surface cracks using a magnaflux procedure.
  • Cylinder bores, counter bores and crank bores are checked and machined if needed.
  • Water passages of the cylinder blocks are pressure tested.
  • Serial numbers, cylinder bore size and work performed is recorded before the blocks are released to the Production Department.
  • Crankshafts are checked for bends and cracks using a magnaflux procedure.
  • Crankshafts are measured and polished or machine ground to OEM specifications.

Complete Examination of Cummins Cylinder Heads

  • Cylinder heads are disassembled with all plugs removed and chemically cleaned.
  • Head castings are measured for thickness before and after being surfaced.
  • Castings are pressure tested with new injector tubes installed.
  • Valve seats are cut to specification on our computer controlled seat cutting machine which ensures proper valve to seat mating.
  • Cylinder heads are assembled using new valves, springs, guides, seals and cam follower rollers and pins.
  • Rocker arms and valve bridges are reclaimed or remanufactured as needed.
  • Cylinder heads are supplied with new plugs.

Complete Remanufacturing of All Cummins Subassemblies

  • Connecting rods are remanufactured with new bushings and all measurements checked utilizing state of the art equipment manufactured by Sunnen.
  • Blowers are completely remanufactured with new bearings and seals.
  • Fuel pumps and water pumps are remanufactured using new seals, bearings and shafts.
  • Fuel pumps are bench tested prior to release.
  • Camshaft end bearings are remanufactured using new bushings.
  • Oil pumps and valves are remanufactured using new valves and springs.

Meticulous Rebuilding of Cummins Engines

  • Engines are assembled by qualified technicians who verify the correct components and acceptable measurements of all remanufactured subassemblies and reclaimed components.
  • Engines are assembled using all new bearings, seals, gaskets and consumable parts.
  • Complete engines are tested to OEM ratings using a 2500 horsepower dynamometer.
  • Horsepower output, rpm, oil pressure, crankcase pressure and air box pressures are recorded along with engine specifications and supplied with a start up inspection report.
  • Engines are rust proofed with a red oxide primer and enamel coated paint.
