G60 belt tensioner compressor

chaps, my G60's belt has sliped off one of the pullies by about 5mm, causing some chafeing to the belt. I need to square it up and posably replace the belt, if its worn badly.

Does anyone know of a good tool to compress the spring tentioner that holds the belt on, as last time it took me ages to get it on.

 

use a rag and lean on it...works for me

 

i think ill need to get down the jim first

 

or maybe to macdonalds...
