Exhaust system
Unless otherwise agreed, the motor will be delivered with the UL power exhaust system. The system
is designed to reduce the noise to an acceptable level without loosing power.
Dimensions of the exhaust system:
Exhaust installation :
The 4 exhaust tubes are fitted to the cylinder heads with 4 screws. Between the cylinder head and
the flange is an exhaust gasket. (See Parts catalogue “Exhaust system“)
Because ULP have to tighten the exhaust pipes during the final test run of your engine, the gaskets
are deformed and have to be replaced. (4 spare parts are in the box)
Procedure :
Unscrew the 4 “M6” screws from each exhaust pipe.
Replace the gasket by a new one.
Refit the exhaust tube, but
DO NOT TIGHTEN
the screws!
After the engine is installed in the plane, install the muffler. (Glide the exhaust tube in the
muffler)
Fix the muffler with the brackets to the engine and install the springs.
Tighten the screws (16x) to fix the exhaust tubes to the cylinder heads.
