Gently rotate the hub to help push the oil out. I would plan on flushing several oil charges worth through the compressor to get the old oil out. One of the other AC guys on here should know if you can/should solvent flush the compressor.
As for distributing the oil charge, the FSM says you should.
This is for a 124 of the same era the 126 should be similar.

Jay Bob. After reading the link you sent I'm still not clear about the distribution of the oil. The link talks about specific component replacement and how much oil to add following a component replacement.
I've determined that my system holds 7.75 ounces. Once I drain the oil out of the brand new compressor, measure and that replace the same amount with mineral oil, do I replace the remainder of the 7.75 ounces into the dryer or other location along the pressure lines to distribute the oil?
thanks
