Paul,
If you really want to do it up right or if you're planning to keep the machine for along time, refer to thread # 28312 in 2010 Imperial Forum Archives. Volvoguy87's posting is very informative.
That fan and drum bearing will probably need a lot of attention by now. It will drink a lot of Zoom Spout oil. Be careful with that fan. You can't get 'em anymore. That fan is worth the price of the dryer alone (if it's in good shape). Try and get some new belts. And felt seal, like Dan said. Those pulleys will need some Zoom Spout too.
Hey, even if you aren't planning on keeping the dryer very long, it's a good learning process.
My avocado 806 is running just like it left the factory. If you hear of an avocado 806 or 808 dryer not too far from me, let me know. My washer needs a mate. My 806 washer has the gold strip along the bottom, under the glass, so I'm not likely to find an avocado 806 dryer in good condition with that gold strip. You know they didn't even make them for a whole year. I want one with a good dial, good buttons, little or no porcelain chips, and little or no rust. An 808 might be better anyway. The parts are easier to find. Tearing that washer down just about killed me. Dryers are usually easier, though.
I have a repair manual for Maytag Dryers, so if you have a question, ask and I'll try to answer.
Brian.
