% Section 71-21 % Engine Mounting - TAE 125 Diesel Engine % 1. General
% Tubular steel makes the engine mount. The engine mount has welded joints. Powder coating protects % the frame from corrosion. Welded brackets hold components such as the coolant radiator and the % intercooler. Rubber lined P-clamps and cable ties hold electrical cables and other items of equipment % to the engine mount.
% The engine mounting-frame has five small mounting pads at the rear of the frame. Bolts through the % pads attach the engine mount to the fuselage. The center mounting also supports the elastomer pack % for the nose gear leg.
% The engine attaches to the engine mount at three mounting pads. Large gel-filled rubber shock-% mounts go between the engine and the engine mount pads. These shock-mounts isolate the airframe % from engine vibrations.
