Small Engines (Lawn Mowers, etc.): snowblower belts replacement, double pulley, thanks in advance

Question
I have a approx. 1978 Beaver snowblower. It is powered by a 7 h.p. B&S engine. Both belts need to be replaced and I was wondering what would be the proper procedure for this project. It looks like that by removing 6 0r 8 bolts it would split except for the double pulley and idler pulleys/springs.
                Thanks in advance

Hi Rodger,

Sorry, I am not familiar with your model.  It seems that you are on top of the proceedure for accessing the belts.  Go ahead and remove what you need to, to replace them.  Often I don't have a manual to work with, so I just take a look and try to figure out a way to do the job, the easiest way.  Let me know if you run into any specific problems once you start.

Good Luck,
Michael
