Motor should slide in. Put glue on and let dry.  Make sure it's aligned properly too.  A plastic guide can be purchased for this.

To ensure the safety and performance, we'd recommend you to send it in for evaluation and get it repaired by engineers. Besides, unauthorized modification will void the warranty, for details, please visit: http://www.dji.com/service/policy
