Bridgeport Series 1 Info Needed

Greetings,

I would like to know if anyone out there has a manual page
of a bridgeport series 1 cnc boss 4-6 head assembly. i have a
maintainance manual but it doesnt have any information on this.
I believe a machine that i'm working on has missing parts.
Does anybody have any torque specs for the spindle spanner nut
torque (the large spanner nut thats screws onto the z-axis ball nut)
cant find that anywhere in my manual either. boy those manuals
leave alot to be desired.

Thanks
Jeff
