Default Update.

I have removed the motor, the bearings are almost seized. Too bad it is 600 volt, it would be simple to replace bearings.
So at present I am adapting another motor to fit this machine, and this one is 220 volt. Then I will be using my existing VFD on it
I have been talking to tech support at Lagun with a guy named Carmen Morrow. He will gladly step you through the removal process and sent emailed instructions. It was such a real pleasure to speak with a well informed senior tech who knows those machines inside out and sideways.
And speaks clear English. When I told him I was putting a different motor on, he stepped me through things to watch for based on others experience, and didn't once try to sell me their parts.
I have a whole new level of respect for this company.

So here are some pictures of the motor, and it's replacement, and the welding required.
First picture is of the existing motor, it has a standard flange register, but has two exterior ears to mount it.
Second picture is the front motor flange that will fit the hole.
Third picture is milling some lugs for the new motor flange.
Then I welded them on to the motor flange, and set it up in the rotary table and drilled the holes in the new mounts.

Here is how the flange looks mounted on the mill.
The next job it modifying the motor shaft, to be continued.

Further progress is happening.
The motor shaft is exactly the right length, but too big, so I have machined it to 24mm.
I decided, just on general principles, to replace the front motor bearing, even though the existing one is fine. I also wanted a 2RS type instead of shielded.
So I checked the motor bell and it seems that at some time in it's past life, the motor bearing seized and spun in the housing, and wore it 10 thou oversize.

Not a big deal as it is still functional, but it would have bothered me. So KeithR talked me into this fix instead of laying in brass and boring it. Just bedding the bearing in loktite was also considered.
I bored out the casting and pushed a little dab of well tubing into it, and now am machining the bearing hole.

I just can't see the sense in taking something apart and not doing preventative maintenance. Now comes the test assembly and then mounting the motor in it's new home.

Done and turning.
It was relatively easy to assemble the motor to the pulley and not have to fight the weight of the whole motor. After that just pile the pieces together.
