Presentation Transcript
slide1

Cleaning engine parts

  • Debris often missed
    • Under side of intake
  • Leading cause of bearing failure
    • Particle contamination
  • Oil pump pick-up screen
slide2

Cleaning engine parts

  • Solvent tanks
    • Small degreasing jobs
    • Safe for all metals in engines
slide3

Cleaning engine parts

  • Cold tanks
    • Safe for all metals in engines
    • Slow soaking process
slide4

Cleaning engine parts

  • Hot tanks - Used for ferrous, nonferrous, or both
    • Ferrous - caustics for iron and steel only (pH 12.5)
  • Both - detergents for all materials
  • Working assemblies may bind in hot tanks
  • Corrosion may take place after cleaning
  • Rinse with water and spray with rust inhibitor
  • No cleaning solution dissolves carbon
slide5

Cleaning engine parts

  • Ovens for degreasing
    • Environmentally safe process
    • Primary chamber for cleaning
    • Exhaust afterburner to control emissions
  • Process
    • Primary chamber heats to 375F to start vaporization
    • Exhaust afterburner (1300°F) oxidizes vapors in stack
  • Primary chamber continues to heat to 700°F for iron
  • After cleaning, the sludge is left as ash
  • Aluminum should be limited to 500°F
  • Slow cooling prevents distortion
slide6

Cleaning engine parts

  • Shot blasting
    • For iron and steel only
  • Shot .030” or larger
  • Minimal labor
  • Parts must be degreased and dry
  • Tumble cylinder heads to
  • remove shot or beads
slide7

Cleaning engine parts

  • Bead blasting
    • Parts must be degreased and dry
  • Avoid threads, oil passages, and cooling passages
  • Glass beads used to remove carbon
  • Tumble cylinder heads to remove shot or beads
slide8

Cleaning engine parts

  • Bead blasting with baking soda
    • Water soluble
  • No shot retention
slide9

Cleaning engine parts

Tumbling small parts

  • Small valve train parts agitated in tumbler
  • Parts are tumbled with small media
  • Agitation in solvent to wash away debris
  • Protect valve stems
slide10

Cleaning engine parts

  • Ultrasonic cleaning
    • High frequency sonic generators
  • Cleaning agents and heat add efficiency
slide11

Cleaning engine parts

  • Other cleaning tools
    • Ring groove scraper – ring grooves
  • Wire wheel – piston tops
  • Bore brushes – oil galleys
  • Flare brush in a drill – combustion chambers
  • Cold acid descalers – removing rust
