My 17 year-old Noma snowthrower has a scored impeller shaft on the
second stage. Last winter the bearing assembly on the stage housing
failed and now the 7/8" steel shaft is about 3/4" for about an inch.
I'm having trouble finding the part although I can get the bearing
assembly. The impeller and shaft are all one piece. Is there anyway to
augment the scored section and restore it to the original diameter? Is
any kind of welding an option? I suspect there isn't any kind of mild
steel duct tape.
Keeping this thing running has become somewhat of a hobby for me. I'm
guessing it's time to get a new one and pay more attention to
Welding and grinding is an option if you can disassemble. Go to a shop that
Can you make an angle iron bracket to move the pillow block (I assume)
bearing over to a good part of the shaft? This could be done with drill,
nut, bolt work - no welding.
Keep the whole world singing. . . .
Try local machine shops see if any do journal repairs
impeller and shaft are all one piece shouldn't be a problem
we have a local shop that does it welded in lathe and cutting keyway
If you don't mind the 6 wk lead time
another that does flame spray 2 wk turn around about $160.00
and then there's always brush plating on site not sure what that

Your easieat way out is to find out exactly where the shaft will clean up, so
have it machined to some reasonably standard dimension. Then contact your local
bearing store, give them the inner, outer and width dimensions you want in a
new bearing and odds are they can pull one off the shelf. If the inner fit on
the shaft isn't perfect, don't sweat it, cement the critter on with red
LockTite and it ought to last for years. HTH
What came to mind to me was to cut a length of 3/4 water copper tubing, and
then cut it length wise with a hacksaw. That shoudl bulk it up a little.
I did something similar with lawn mower wheels one time, when I had a couple
really wobbly wheels on a walk behind mower.
