Here is a link to a video that Aircraft Specialites
made of a cutaway starter adaptor with a Iskra and a common old-style Presolite
motor.
Basically it just shows the sliding worm gear not
retracting all the way and it shows the end of the worm gear shaft no
relaxing.
The mechanism needs to be able to unwind a bit so
to relax the clutch spring after engagement.

I just put a skytec
starter to replace my iscra. Replaced one drive under warranty.
The skytec has a solenoid which disengages the motor from the starter. The
permanent magnet starters can create drag on the starter spring which results
in wear. Cirrus does not allow Continental to ship them motors with the
Iscra.

Also
had to replace my starter drive on an IO-550 in a Legacy. Unfortunately,
engine mounts had to be loosened and engine swung forward.
Apparently,
different starters vary in their tendency to kill the starter drive
adapter. My understanding is that the Iskra is the worst and that the
old Prestolite is the best. Allen Barrett can probably give you further
information.

I
know there was some discussion a while back about starter drive issues, but I
can't find any specifics. I've developed a problem where the starter
slips and won't engage, so I suppose I'm a victim of the TCM problem at 400hr
TT. Is is possible to remove the adapter without moving the engine
forward? I have an A/C pump on the back of the engine too, so it's very
packed behind the engine. I'm not even sure what to remove. Anyone
have some ideas to make this as easy as possible? Any
photos?
Thanks
Ron
