bent Champion 400 blower crank arm

Recommended Posts

I am refurbishing my champion 400 (just needs cleaning bearing check and paint) but the crank arm is bent about 20 degrees. The handle end just hits the blower housing. Problem is how to straighten the arm (hot, cold ???) I definitely don't want it busted. The arm is somewhat an oval shape and I believe it is a newer model blower. The bend must have been due to a light fall as it bent just ahead of the connection point to the blower gear assy. Thanks for any help, jgvarno

Should be able to straighten this cold. Lay it on the anvil with the hump up, put a block of wood on the top of the hump and smack the block of wood a couple times until the arm is straight. You might want to put a board underneath also to protect the contour. Or just clamp the short end in a vise and pull the long end to get it close.

I have adjusted many over the years. if it's a good bend,, I heat it. If it's simply an adjustment (tweak) I do it in a vise cold.
