How do I get mold out of my vacuum?

Every time I vacuum My vacuum spews a nasty musty smell out of it. I know the smell to be mold or mildew and I have replaced both the bag and the filter (of course), as well as wiping out all the inside parts that I could get too (even by disassembling it as much as I felt comfortable doing). And even after all this my vacuum still smells... HELP! I know most would say take it in and get someone else to clean it or toss it and buy a new one but I am totally strapped for cash so that is really not and option. Any other suggestions?
