What's a cf28222? Never heard of one. Maybe you meant cf2822??
What is it that you cant tighten?
Which grub screw is stripped? Is the screw stripped (highly unlikely) or is the thread stripped in the motor housing?
Why so many emoticons?
Problem has to be stated simply and clearly if specific reply is expected. No?

I think so he has stripped the threds on the motor housing , he might have over torqued it . If that is the case then you are in trouble , if you have stripped the threds of the screw , well then you can simply change it .

Re: STRIPPED GRUB SCREW PLS HELP

i think the threads are fine... he strips the inner hole where we put allen key.. (coz i too experience this many times)
the only solution is either use over size allen key or grind slotted screwdriver (on stone grinder) and try..
good luck Thumbs Up

Re: STRIPPED GRUB SCREW PLS HELP

What I usually do for such a thing is to convert it into minus screw . Just take hex blade and run it over the head , if you have small rotary tool use a cutting disc .

Re: STRIPPED GRUB SCREW PLS HELP

hmmm that would only work if screw is outside the housing(i.e hole). if it strips while screw is inside its housing( which happens in most cases) than only oversize allen key will works... Wink

I dont think an oversize allenkey will work here..
Shocked

Cutting the topedge using a rotory cutter
Or
Use a small new allenkey 1.5mm L shape
Put a drop of super glure in tip of that and put it in the stripped hexnut.. after a minute try to unscrew it.. i am damn sure it will succeed, may be you need to repeat for 4 to 5 times..

Re: STRIPPED GRUB SCREW PLS HELP

For same motor , i also experienced same . Allen key was slipping over Grub screw. Went to local hardware shop . The guy put BL motor rotor flat on his wooden table (inner core removed ) and pushed belly with hands against table . Shaft slips so Grub screw loosens. Also you can use 1/16 inch Taparia Allen key for such Obstinate Grub screws :-)
