where do you get the screw to hold on fan for LSJS 3mm plug?


Didnt find one with my Alpha A4 kit or with the motor or plug, would a regular 3mm machine screw work? Do I need a toothed washer? Thanks for the help-

You should've gotten one with the stock fanunit in the box....same bag the green locktite came in.
Anyway, its a small countersunk head type of screw without a washer.
Whatever you use replacing it with (toothed washer included) make sure it doesn't distort the rotor when you tighten it down.

Thanks a lot, I'll look again for that screw...


I would assume you would lock tite this screw... I will- thanks again-

No locktite on it!
That green stuff was to glue the stock plug to the motorshaft, it's almost permanent!
Don't use it on anything else!
I smear some clear silicone on the threads but the screw holds pretty well without anything.
Thats on a stock power setup.
If you're running a hipower setup(like a LSJS).
Add a dab of CA under the rotor. It helps keep it from slipping.

I used green threadlocker for the plug, and blue threadlocker for the screw, it's not permanent. I've had it come off before. Also, I'd recommend using a flat washer. If you notice, the countersink on the rotor isn't drilled by a machine, it's hand drilled. I had a couple of rotors that aren't drilled perfect and caused the rotor the wobble. The washer keeps it flat no matter how it is drilled.

Thanks for the info, I meant blue Loctite, not the green...


I've read about how strong the greenstuff is.. I found a 3mm countersunk screw fits perfect, will try flat washer also, thanks again-
