tantofolder Posted June 27, 2013 Share Posted June 27, 2013 More details would be helpful.Is it an electrical blower? Can you remove the shaft from the housing?Photos may help too.Have you tried liquid wrench or pb blaster? Maybe a propane torch to help loosen it?

123samic Posted June 27, 2013 Author Share Posted June 27, 2013 hi tantofolder it is a buffalo hand crank blower. and is liquid wrench similar to wd40? Link to comment Share on other sites More sharing options...
Glenn Posted June 28, 2013 Share Posted June 28, 2013 WD-40 In 1953, a fledgling company called Rocket Chemical Company and its staff of three set out to create a line of rust-prevention solvents and degreasers for use in the aerospace industry, in a small lab in San Diego, California. It took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40®—which stands for Water Displacement perfected on the 40th try—is still in use today. Reference Liquid Wrench Since 1941 Liquid Wrench has been making premium lubricating, penetrating and protecting products Frees stuck nuts, bolts and locks. Dissolves rust and cuts through grease. Quickly penetrates corrosion. Use on garden hose nozzles, clamps, pipes and frozen mechanisms. You want to displace water or penetrate corrosion.?

Glenn Posted June 28, 2013 Share Posted June 28, 2013 More internet research on the issue yields PB Blaster. This stuff WORKS. And if it doesn't work - then you didn't spray enough or let it sit long enough. And if it still doesn't work - then spray it again. Kroil Kroil's high solvency penetrating oils first penetrate to one-millionth inch spaces to break the bond of rust and to provide lubrication at the first molecular level. This frees the frozen metal part. There are other products out there as well as home brews that can be used. It did not rust and lock up in seconds, so go slow and let whatever you use have time to work.. Link to comment Share on other sites More sharing options...
Jim Coke Posted June 28, 2013 Share Posted June 28, 2013 Greetings 123. Everyone has their favorite brew for freeing up stuck parts... Rust is rust and unless you can get the lube to the rust it will take a very long time... I have restored tons of old machines and found a small amount of heat and tapping the area that is frozen will compress the rust and allow for material to do its job.. Apply cold after tapping the stuff will ignite.. Don't beat it just taps . On big stuff I use pneumatic hammers.. Always works... Good luck Jim Link to comment Share on other sites More sharing options...

Don A Posted June 28, 2013 Share Posted June 28, 2013 Agreeing with Jim, if you use heat, like a propane or Mapp torch, try to concentrate the flame on the collar of the fan and keep it off the shaft as much as possible. Any little bit of expansion you can get will help break it loose. Link to comment Share on other sites More sharing options...
123samic Posted June 29, 2013 Author Share Posted June 29, 2013 Thanks guys! I used a propane torch and gave it a few taps and it poped right off. Thanks again, Sam Link to comment Share on other sites More sharing options...
