Mountain Bike Crank Size

how do i replace my crankset on my genesis v2100 mountain bike?
i recently stripped out a crank arm on my Kent Genesis v2100 26 inch MTB from wallyworld, can i replace just a crankarm and not the whole set? also what are the specifications like arm size, style, and everything i need to find a new one. GREATLY APPRECIATED!! i’d like to ride again w/o buying a new bike!!!
thanks, john
Check out the video from Bicycle Tutor.com. That should help tremendously. But I would still do a double check with your local bike shop to insure you have all the right tools needed, etc.
