Bridgeport manual needed

[bherr]

I have a Bridgeport Series II Interact 4-serial # 60653108A, at least I think this is the serial number as I found it on a plate behind the circuit board in the oil compartment. It also had these numbers below the serial number, 86782.
I'm willing to pay anyone that has a maintenance manual to copy and send to me.
I'm having trouble with the spindle motor, Cantraves and need to check the brushes, but don't know how to get to them. My work is backing up, please anyone.

Remove the cooling fan. I believe the brushes can be accessed from there. What I cannot tell you is a source for these brushes.

machintek,
Well I was reading thru the contraves book and noticed some penciled in wording that mentioned pin 19 to pin 21 on the one board. I noticed that a jumper was in pin 19 but not into pin 21. I called the previous owner and asked him about this but he couldn't remember. I decided I had nothing to lose so I touched the open end of the jumper to pin 21 and the spindle started truning. I shut down the power and hooked this wire up, but the spindle didn't turn, so I disconnected it, and then powered the machine back up. Launched the program and then touched the wire to pin 21 and the spindle started turning. I then left the wire disconnected and finished milling the program. the best I can figure is that this wire trips some relay that shuts down the spindle for whatever reason. I guess at some point I'll be replacing parts but for now I work with the status quoe.

thanks for your help.

Very good! Glad my notes helped. Still not normal to have to touch this on an intermitant basis.
