Another one of those 'fun' jobs.
I use a spare mainshaft  as an alignment tool.  The only way to get them 
lined back up without damaging something,   you'll need to split it down 
to the spring bars. Two massive screw drivers,,,,you can lift the two 
crossbars (that the pressure pistons push on) to release clutch pressure 
and let you slip the shaft in to align the splines .  Don't be surprised 
it it's not just rotational alignment but actual  linear alignment as 
the annulus cup could be out of alignment

ptegler

When you say seperate the o/d..... are you talking just separateing the 
adapter or splitting it further back?  the adapter housing

I have the D-type.   Based on responses and a couple of videos I found, it
appears that I need to reduce spring pressure no matter what to be able to
get the splines loose enough to rotate.  So it looks like I need to loosen
the fasteners that secure the castings on either side of item 26.   Image
of D-type attached.  I can just imagine another (future) oil leak.    Still
a bit surprised the splines shifted when all I did after removing was to
pour solvent into the diff and slosh the solvent around.
