A.o.A my 10kva generator with 1.0 liter vitz engine is making knocking sound coming out of coupling area. I made video of the sound and send it to the engineer who made my generator he said that your generator coupling plate is broken and needa to be replaced but for the past 3 weeks i repeatedly tried to contact him to come over for replacing coupling plate but he doesnot want to help me.
