Replacing Alternator

[Mike_420]

Hi guys, im gonna be replacing my alternator tomorrow as the one on my vtr at the moment is making a very loud whirring noise, i presume the bearings have went in it.

is this just a straight swap over, do i need to do anything with the belt? and will it need replaced or will it be ok to use until i can get a new one?

and also what tools will i be needing?

thanks :)
