Lincoln magnum chiller

I check my welder for dust and the cooler for water level alot.......Probably just a habit I acquired through the years but I guess it's a good habit.....Well I noticed a "Squeak" noise coming from the cooler and I had some time so I took the cover off this morning and found that the nylon fan had lost it's fit on the motor shaft and was slipping (Not turning)  I took the motor out of the cooler frame and saw that the motor shaft had a flat spot on it for like a set screw ?  evidently the fan is glued on from the factory with a small clamp that holds the fan on the shaft along with the glue  I cleaned everything up and mixed up some JB Weld and glued the fan back on.....Must have worked because the squeak went away..... weird   Miller Dynasty 350Twenty Six HammersThree Crow BarsBig Rock

Reply:The nylon might have originally had a molded hump inside the hole to match the flat. Lots of modern small 'plastic' fans have just a spring band on the hub to create enough friction to keep it tight on the shaft; some have both that and the lump. Sometimes when epoxy wont stick to plastics, first coating the plastic with cyanoacrlate (e.g. superglue or equivalent) will allow better adhesion.
