I threw my iskra(p) away and bought a Presolite.
I know, big and heavy…big and heavy…but hey, it’s nice to my
engine…

problem IO550
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.

drive problem IO550
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.

TSIO550
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
