72AMFpolarbear

Hi Sam, I own a 1972 AMF Polar Bear 3-stage blower and have all of the paper work that came with the blower when bought NEW. The model number is 13620500, the paper work includes exploded views of the whole blower. It sounds like your unit needs quite a bit of work. If you have the 8hp tecumseh model #HM80 155027 ENGINE, parts are still available from tecumseh. The blower I have is in excellent condition and works great, yet I am always looking for a spare blower, please let me know if you decide to sell yours. If you would like copies of the paper work I have please let me know. GOOD LUCK!
