Save-A-Turbo
with Berryman's B12 Chemtool

Turbochargers are simple one-moving-part machines that provide immense increases in piston-powered aircraft performance and capability. Pressurization, pressurized heated air, and sea level horsepower at altitude are efficiently available for turbocharged piston engine aircraft.

Turbochargers will usually last through the life of the engine with good maintenance such as: proper leaning, ample run-down time for bearing and lubricant cool-down, timely engine oil and filter changes.

Since maintenance and operational practices are not always known qualities, the following is recommended on an annual basis to help keep the turbo bearings and seals clean.
Following these steps may save your turbo from premature replacement.

  • To apply B12, cap the turbo scavenge port and fill the turbo oil cavity with
    Berryman's B12 Chemtool.
  • Cap the turbo oil supply port and allow the solution to remain in the turbo cavity
    for at least 24 hours.
  • Turn the turbo through several revolutions by hand at least twice during the soaking process.
  • After the soaking period is completed, drain the turbo cavity and flush with mineral spirits.
  • Hook up the oil scavenge line. Prime the turbo cavity with a cup of engine oil and connect the oil supply line. The turbocharger depends on engine oil pressure for lubrication and cooling of the bearing and seals.
  • Taxi at idle, or idle the engine for a minimum of three minutes before shutdown.
    This allows time to cool the turbo bearings and seals so as to minimize and prevent coking of the oil. Coking causes stuck bearings and results in a dragging turbo with probable oil leaks.
  • This same procedure will often correct an oil leak at the compressor or at the turbine bearing seals.
  • Berryman B12 is available at most Auto Parts Houses, or through RAM.
