Champion Blower 400 Series issue

[Topher-Folkmar]

Hello all,

I have just recently inherited a Champion 400 Series Forge blower (along with forge). I have taken it off the forge to examine it, and I have discovered that it is not working properly. It seems to have a number of things wrong with it, but I have worked most of the issues out. I can get the cogs to turn, but the handle just spins inside the large cog. It is virtually useless unless the handle will catch and move the cog. I would take it apart and examine it further, but I am at a complete loss on how one would go about doing that. Any suggestions?


Thank you for reading, and thank you for any input.

There was a real good description on taking apart and fixing Champion blowers at Practical Machinist awhile back. You could probably go to that site and search for it. Hope this helps you

This is a great help to me. Thank you very much. I've pinpointed what the problem is, it's a "key" lock that locks into place in a groove on the large cog, and in another groove on the hand crank shaft. I still will have to disassemble the blower in order to fix the problem, but it should fix it. There is a considerable amount of rust, due to weathering, and It will take some time and precaution in taking it apart, but nothing out of reach of a blacksmith, eh? Again, Thanks for your time, and this has saved me hours of headache.
