Good grief- if I only had $108 floating around - -it would be headed for
Oakland. Two times over, easy!
If your iRoast is howling on start-up, the bearings are dry and worn on the
1. Take it apart and pull the motor out
2. Remove the impeller from the motor shaft
3. Take the motor apart and remove the armature (the rotating
part)-don't lose the spacers
4. The bearings are phosphor-bronze cylindrical bushings, probably
have an oil felt each. The felts dried out and the bearings wore because
they were run dry.
5. Clamp a 3/8" dia pin punch in your vise.
6. Support the cylindrical end of one of the bearings on it.
7. With a 1/16" dia pin punch, swage the bushing at the other end, to
pincushion the bearing bushing and take out some of the free clearance. (A
sharp centerpunch would work, but you could easily shatter the bushing if
you tap it too hard in one spot.)
Re lube the felts with something heavier than the likely original sewing
machine oil. Use any oil you have- the original didn't work too well.
Reassemble the motor/blower/roaster.
