Well my fan motor EXPLODED! :lol: :lol: :lol: :lol: Tested insulation with mega :zap: thats OK , ran up motor , bearings sound a tad dry , checked shaft :palm: Looks like it has had an ill fitting pulley on it some time in its life ,,,,,,, the price you pay for using salvaged parts :coffee: and the centrifugal switch contacts could do with a clean . So its repair motor first job tomorrow :dremel: Rob |

Yikes! Wait a minute...... It didn't really explode, you just took it apart to make sure it was in perfect running order. Why I oughta.... |

Evening Lads :beer: A wee bit done to the motor , pressed off the bearings . Ground the shaft end parallel with the good old tool post grinder :dremel: And pressed one of the new bearings back on the shaft . Now when I removed the motor fan cover one of the wee screw heads sheared off . Well corroded in as per with ally and steel . A bit of heat needed ,for jobs like this I use a heat gun .waist of time trying to use penetrating oil at this point . File a couple of flats on the screw if poss , don't cut a slot for a screwdriver or you will be getting the drill out , warm the ally part up , just wiggle the screw back and forth to crack the bond once its loose a bit then spay some penetrating oil on . been using this method for yonks on motor bike and outboard engines .

Conventional advice is if you must use a tool post grinder, cover the ways in damp newspaper first, then after use, a good clean up and re-oil. Grinding grit trapped under a way wipe can cause no end of damage. |
