Hello All this is my first post.I have a champion 400 handcrank blower that may need to have bearings adjusted or replaced .Can anyone give me info on how to do these tasks. Any help much appreciated.

I used bearings intended for use in a bicycle steering column to replace the bearings in a Champion 400 blower years ago. If you have a bearing dealer in your local you could remove one of them and take it there to match it for a replacement. Our area used to have two bearing suppliers, but I don't know if either still exists. If you put your location in your profile on this forum, then someone local to your area might be able to tell you what supplier in your area has what you are looking for.

I already have the new ball bearings. Is there a way to align fanshaft in bearing or is it self aligning. With the new bearings inplace crank seems to be a little noisey.

The tapered nuts will adjust the shaft to run true and well...don't tighten too much or the resistance can be hard to crank.

There are six bearings on the 400, you may need to replace them all.
