Due too a recent accident I need to replace a few part's in one of my tail rotors. After pulling prints, and researching all web sources now I'm really baffeled on my output shaft and a new hub I'd like to replace in a plain MA plastic gear box.
Here goes' hope some one know's how to chase the correct replacement hub number
MA 0429 output shaft it's pretty standard and basic.
Bird currently has a solid hub which may be tweaked from accident.
Wanted to switch to a up dated dampened hub MA 0446-1 : shown on my prints : " It's a old #" I run one on my other gasser and I like it.
" # is missing on all suppliers web's" " vanishes with no crosses"
Chasing #'s and same bearing sizes lead me too a MA 0541-7 which I believe is back to a solid hub !
Chasing this MA 0541-7 number with it's bearing sizes --
Ref's me back to a MA # 120-58 ??
Which I have no clue if it's a solid or dampened or if it will fit the standard MA 0429 basic output shaft
I just want a hub
Gosh golly : I just want to swap out an out put shaft on a standand plastic gear box case and toss a suspcious hub, with a wee up grade.
Hub's, Hub's, Hub's - Whos's the prophet in the land on the Hub's and their number's ????
Some one please throw me a rope
Save me ! Or else I may use it for a unentended purpose - in that case just drive me over to the bridge !!!
First photo is the dampened hub - last photo solid hub
More diggin !
MA 122-65 " say's need to swap bearings to a 5mm X 10" X what mm?? thick ????
Theirs one more but's it for the Razor
