Gen V rebuild promblem

[chrisb]

hey guys i normally dont ask for help but im not sure on this one.

Heres the story I rebuild my gen v with new snout bearings, coupler, and the rear needle bearings (by the way there m112 needle bearings) and with it back together it makes a clunk noise when you turn the rotors back and forth. i cant remember if this is normal play? it turns great except the noise.
I have narrowed it down to one rotor that is not drivin off the snout that makes the noise. Can anyone rotate there blower back and forth and see if it makes the same noise?


heres a vid.

seems like normal gear backlash to me.... i know my gen 3 does that and it works fine lol

My Gen III did something similar when I got it together. Different from coupler play since I used a brand new coupler.

ive taken it apart several times and cant find where its hitting the case or rotors? just kinda werid it didnt do it before untill i replaced the needle bearings in it.
