[R-390] RF sub chassis slug rack problem

[David Wise]

Some kind soul on this list once sent me a bunch of spare racks.
I used one or two, and the rest are just sitting.  I'll be out of town
for a week, but when I get back I'll tell you what I have.

Hi Group

I'm new to the group and am restoring a 1963 Teledyne R390A.  I have a 
problem.   I'm cleaning all the slug racks and roller bearings and one 
of the rack's bearings are frozen tight.   They have appaerently been 
this way for quite a while as grooves have been worn on each side of the

bearing where it slides up and down the mount.   The outer bearings on 
this particular rack that roll on the cams are ok and cleaned up well.

I just can't get these inner bearings to unfreeze.  That's right, both 
sides are like this.   All the rest of the slug racks have been cleaned,

reassembled lubed and replaced.  This rack has been cleaned lubed and
replaced but I would like to either replace or fix it.

Any ideas ? 

Thanks guys...... I used the R390A 's in the Navy and and NSA during the
cold war and Vietnam.  What a machine/rig!!!!!
