The brushes looked good as did everything else . I'm baffled. It is all buttoned up and I have to rip it apart. All in all I guess I shouldn't complain. I was just looking at those chinese digital read outs on E bay. 400 bucks with custom scales.

Installed the big 90 volt motor which is a Peerless Winsmith 183-18-0288 on the X'Y gear box. The mechanical end works great but the motor is throwing a blue arc from the brushes. Back to the drawing board!

Good old 10W-30 in the oiler. 90 weight in the gears for the Harmonic drive and ****** fluid in the drive itself. Also 90 weight in the traverse gear box. followed by a quick paint job. Then onto the surface grinder.

The spindle is operating correctly and I just finished the harmonic drive on the quill. Also working. I only have one of the large 90 volt DC motors and it is on the knee (Z) I removed it and took it apart. The ground wire had shed its insulation and was arcing near a brush. I took it completely...

I just brought up this thread and found you beat me to the punch. Yes the oiler is important, it will not run without it. There is a wire from the start switch #33 that passes through the oiler (wierd) but that is how it works. I have an emergency stop button which I want to leave off. As it...

The oiler has black, white and ground, it operates at 120 volts. There is no way it could trip out the spindle motor. I looked at the CNC Mazak I run at work. It has the same type of oiler but; downstream attached to the oil line there is a pressure switch that is wired into the ladder in the...

Mine is a Bijor oiler. I think I will take it apart and clean it up. I never would have thought of the oiler being in the circuit. My machine is wired 460 .

Took these while disassembling

I picked mine up for 500 at an auction . It was never used for anything other than aluminum bar but the electrical was a little butchered. The 90 volt motor from the Z feed is missing and I can only find one for 2 grand. The main motor is 460v 4 HP and runs great. To run it I have to hold the...

I just picked up a series 2 4j. I have it set up in the garage and it powers up but I have some wiring issues. I have the schematic for the quill and the 90 volt board but I can't find the general wiring diagram I will help you out with what I have can you help me with a wiriing schematic. Colin
