Re: New motor for G4003G wired differently than original...LATE UPDATE
I finally got the gremlins chased out of my lathe!
Just to recap: My issue was first diagnosed as a bad capacitor. It was because there was sticky grey goo oozing out of the seam. No problem, Grizzly had a replacement here in two days. Not bad, except that wasn't it.
It was caused by a loose connection from the factory here:
Since the cap didn't fix it they sent me a replacement motor. It didn't work either.:angry:
After spending quite a while on the phone with the head electrical tech he determined I needed this transformer:
That wasn't it. It was then determined that the culprit had to be the forward/reverse switch (which is a PIA to change!:
That wasn't it.
After a bunch of jumping wires/connections there was an outside chance that the reset switch could be the issue. This little bit of kit did the trick:
I'm very pleased now. During this ordeal I learned I had a motor from the factory with bad bearings! Before they replaced the motor they had me remove the motor from the lathe and disassemble it to check the contactors. I had to pull the end and the fan off to get to it. It ended up being on the other end of the motor but no biggie. It gave me a chance to at least check the bearings. They were a little rusty but they were as grumbly as hell! My lathe had a slight vibration as I keep a mag base dial indicator on the headstock and the needle has always danced and I could feel a slight feedback through the levers. After reading here and elsewhere as well as consulting with my friend Tom I accepted that this was a light lathe and it must just be the nature of the beast.
Well guess whut? It ain't! After getting this motor finally running (and in the right direction!) I HAVE A NEW LATHE! My dial indicator no longer bounces the needle! The lathe is so smooth it's like it's not even running as compared to before!
I just turned these parts yesterday and this is the way they came. They haven't been polished/finished with emory cloth, file sandpaper...nothing. I've never been able to get this kind of finish. This is exactly what they looked like outta the chuck:
Thanks a million guys for all the guidance and suggestions. I'm now, after the nightmare, a very happy, happy guy!
Thanks again,
Dale
