How does this affect me?
This document should provide further guidance for the lubrication system with respect to:
- purging
- venting
- to avoid air in the lubrication system
ROTAX® was informed of a limited number of engine failures in the field resulting from a lack of proper oil purging after the engine had been first installed and /or the engine had been re-worked.
This Service Instruction should help to make sure that the engines do not suffer such engine failures in the field. As air can be trapped in the valve tappets and cause valve train failure it is very important to complete these instructions in their entirety.
