Engine Build

Katech provides OEMs engine development and testing solutions that can significantly reduce product development time and cost.

Katech’s rigorous assembly process covers pre-assembly measurements, clearances, assembly procedures, torques, adhesives, lubricants and other aspects of engine assembly. Traceable records are maintained for future reference. Quality control is maintained through progressive inspection and procedures.

  1. Disassemble, wash and inspect parts
  2. Crack check using Magnaflux (ferrous metals) or Zyglo (non-ferrous metals) if necessary
  3. Chase all threads in cylinder case and clean
  4. Measure main bores, line hone if necessary
  5. Measure lifter bore clearance
  6. Measure cylinder bore
  7. Hone cylinder bores using deck plates
  8. Measure bore finish with profilometer
  9. Weigh pistons, connecting rods, rod bearings, pins, locks and rings to determine crankshaft bobweight
  10. Balance crankshaft
  11. Polish crankshaft journals
  12. Tack weld crankshaft trigger wheel
  13. Hone piston pin bores and connecting rod small end
  14. Polish piston pins (excl. DLC-coated pins)
  15. Deburr piston round wire locks
  16. Measure ring lands for back clearance
  17. Deburr piston ring ends
  18. Gap piston rings
  19. Measure main journals with air gauge
  20. Measure big end of connecting rods with air gauge, hone if necessary
  21. Size main bearings with air gauge
  22. Measure connecting rod bolt stretch
  23. Size rod bearings with air gauge
  24. Measure crankshaft endplay
  25. Measure piston pin endplay
  26. Measure connecting rod side clearance
  27. Check piston to deck height
  28. Deck block if neces
  29. CC piston dome volume
  30. CC cylinder head chamber volume
  31. Deck heads if necessary
  32. CC intake port volume
  33. CC exhaust port volume
  34. Measure valve guide clearance
  35. Measure valve spring pressure and coil bind
  36. Check valve spring retainer to seal clearance
  37. Polish camshaft
  38. Measure camshaft specs with EZ Cam
  39. Degree camshaft
  40. Measure piston-to-valve clearance
  41. Measure valve radial clearance
  42. Measure vertical valve drop
  43. Measure camshaft endplay
  44. Measure lifter preload to determine pushrod length
  45. Calculate compression ratio
  46. Torque all fasteners to spec
  47. Document all measurements and torques in engine build book
  48. Perform engine dynamometer validation

Engine Testing

Katech maintains three Engine Dynamometers Cells geared for performance applications. Two are rated over 12,000 RPM and 1000 horsepower, the third cell is rated at 12,000 RPM and 3,000 horsepower. All cells operate with multiple fuels, allowing calibration over a wide-range of applications.

The Katech Motoring Cell measures parasitic losses for a range of engine components. The Katech Valvetrain Cell provides physical testing, from cam to valve actuation. The Katech Fuel Flow Cell tests fuel system configurations prior to first application.

The six test cells are also used to provide several other critical engine tests, including cylinder pressure and engine air flow.


Katech Corporate Services is also focused on the needs of other markets that benefit from our expertise in engineered machining solutions. One such market is correctional facilities.

Hanging is a common form of suicide in jails and prisons, and drain holes in inmate beds can be used for hanging. HoleLocc, one of Katech’s latest corporate products, eliminates the opportunity.

Each Holelocc plug is precision CNC-machined from American steel, built to last. The patent-pending design is highly engineered so it cannot be removed by an inmate. And, critical to correctional operations, HoleLocc is rapidly installed with minimal disruption to daily routine.
