 Hello Vetteman,

  We wouldn't suggest running the engine that way.

 If the bearing is loose then something is wrong. If the engine is used, I imagine it was overheated then the bearing was able to spin which in turn makes the hole larger. That will allow the crank to contact the case and cause more problems like lack of power, over heating and metal debris that will cause premature wear and failure of the engine.

If the engine is new, you should send it in along with a copy of the proof of purchase from an authorized dealer for repair.

Wookie77,

Thank you for your unbiased opinion. I thought about trying bearing lock, but it is a brand new engine, and I think as a Saleman working for one of the largest Heli Sales Site, I was given the wrong info from them. It's possible he didn't understand the question, so I'm going to forget about their answer. I am a Commercial A/C Mechanic, w/ 22 years on the job, and deal with motors, pumps and seals all the time.I do believe it would cause the machined area to enlarge and cause major damage to the engine. I will contact Thunder Tiger to try and get this engine replaced...another setback...shsssh. Thanks for your time & thoughts, I appriciate it!
