is it a really redox reaction....
you can simply notice that both sides' electrons haven't balanced....
also the left hand side don't have any H atom...
from my view, i think the reaction should be...
Al + MnO4 + H2 + e- ----> Mn02 + (Al(OH)4)-
after balanced
Al + MnO4 + 2H2 + e- -----> MnO2 + (Al(OH)4)-
i hope it is correct since I am not very gd of this but I am try my best to help you~^^
