I was astonished to examine the abnormal noise observed from RGB when GEN was removed found no abnormal during hand rotation. when the generator disassembled found rotor has rubbing sign but bearings are absolutely normal. what could be possible reason of rotor and stator are staking each other when bearing are servicable

Dear NATOPSI

Sir i have investigated the generator defect it was really bearing problem which you have mentioned. End plate bearing was wear off , due this reason stator & rotor stack each other The generator is CID part No so there no provision of bearing failure system any how A/C was escape from happening

Once again apology delay response

Investigation revealed that problem with bearing end plate.clearness increase due to temperature or at time of bearing replaced the proper clearness was not checked as per T.O so bearing outer move wear off the bearing as my opinion. are you agree Sir NATOP1
