Working with a friend on his -7A --- less than 250hrs total, and on his second Skytec starter. The first was replaced under warranty because of looseness between the starter motor and the gear drive. We checked his starter yesterday, during an oil change, and discovered the same loose condition. This starter had the same issue on last oil change and the (2) connecting bolts were tightened and safetied.
What we found, this time, after removing one of the bolts, is that the motor housing bolt holes are significantly larger than the bolt. There are only (2) small (3/16?) bolts holding the motor to the gear drive and the bolt we removed showed significant fretting/stretching/deformed. I believe that the torque is allowing the motor to shift due to the larger hole in the motor flange and wearing at the bolt.
This is the "NL" version of the starter. I was wondering if anyone else has seen this issue? We are placing a call to the Skytec folks on Monday to discuss the issue.
