So, I got this old enco mill. Bad motor. Good cone pulley.
My plan is to pull off the cone pulley and scare up nearly any suitable C face 3 phase 1hp motor, fabricate a mounting system based on the old mounting plate and mount the pulley.
Problem- I tried to remove the pulley's set screws. No luck! I figured that it would be a metric allen screw. Well, there are 2 different sizes. I found a metric allen wrench that seemed to fit one of them pretty well. I cleaned it out, put in kroil, held the wrench with pliers, held my mouth just right--and still, it smeared rather than break free. Dang I hate that feeling. You just know immediately when a hex wrench it not biting in properly.
The other screw seemed to be an imperial size- at least none of my metric set would fit at all. Same thing- I got one to fit pretty good- not perfect. I tried as carefully as I could, but it smeared.
I guess they put "roc-tite" on these things in Taiwan
So- what next? easy outs? I have a surface grinder, so I had the thought of carefully custom grinding some hex keys just for this purpose.
I may take it up to a motor shop and have them look over the motor, oh and by the way, can you take off that pulley?
