Sometimes when I turn the ignition key on my Rotax 912UL, the starter makes no sound and does not turn the prop. When I turn the prop to a new position by hand, it cranks normally. Someone said worn brushes. Does that mean the starter motor needs to be removed an overhauled? Is this a gradual deterioration (only happened 3 times) or will it soon not crank in any prop position?

What issues will I find removing the starter? Any special tools, warnings, obstacles, etc?? Should I send it to Lockwood Aviation? Thanks

The problem you are describing sounds like you are experiencing is due worn out brushes on the starter motor. If the brushes are not of good quality (low density material) or the armature commutator segments are eroded from electrical arching, then premature failure of the starter motor can be experienced. Never replace brushes on any motor without first carefully examining the armature commutator segments for a Britte clean surface less any eroded or blackened segment surfaces. If you seek out a local electrical motor shop that services and performs motor repair, you will learn some very useful service tips that will be useful in dealing with trouble shooting compressor, heat/cooling applications etc. The Internet also provides a wealth of information on servicing just about anything.
