Reciprocating and Rotational Engine Balancing

An engine imbalance can cause harmonic distortion in flight controls, instruments and airframe.  It's one of the leading causes of premature engine wear. Improving internal engine parts balance will produce a smoother running engine through reducing damaging vibration levels.

ATC is the only aviation repair shop in Ontario that has the capability to complete in shop reciprocating and rotational engine balancing.

Reciprocating mass encompasses the piston, piston pin and plugs, and the upper half of the connecting rod assembly. Improving reciprocating part balance will allow your engine to deliver more power to the propeller, rendering the engine more efficient and decreasing wear on the internal moving parts.

Rotational mass balance is the movement in the rotational direction as the engine propeller turns. It's made up of the crankshaft, counterweights, gears, and large end of the connecting rods, connecting rod bolts and nuts, and are factored for oil weight.

Lower vibration levels means:

  • Increased engine longevity by reducing wear and fatigue
  • Reduces maintenance costs by reducing engine component failure, like baffles, exhaust  system, alternator brackets, engine mount etc. from cracking and fatigue
  • Lower airframe and flight control fatigue
  • Reduces premature failure of instruments and avionics
  • Reduces pilot and passenger fatigue
