Neil's advice was right on.   When installed, there should be virtually no side play but there is nothing to restrain it when removed from the engine other than the pilot bearing on the prop shaft and that alone would allow it to wobble about quite a bit.  The clearance on that bearing is fairly large in order to flow enough cooling oil for the gears.

PS:  Congrats on getting 400 hours in your plane Christian, and to Bob on that great article in Experimenter.  I always get a kick out of hearing that rotary powered planes are out there and flying.

>> Hi all
>> Just wondering whether anyone can tell me what the play side to side should be in the rd1c gearbox input shaft and what to expect from the oil seal, i can move the input shaft a little and see a visible gap on the input seal once removed from the motor.Motor has done approx 400 hrs.
>> Just reinstalled the motor after some work and noticed oil dribbling from under the flywheel, thus why it was removed.
