HELP!  Bill Gingerich has kindly offered to fax me  some good 
instructions, but I thought I'd ask the Font Of Automotive Wisdom  on 
this anyway.

I'm still stuck trying to disassemble my GT6  gearobx.  Got the 
layshaft out, but the cluster gear is still loose in  the bottom of 
the case.  Got the input shaft out easily.  The next  instruction says 
to drive the mainshaft backwards to push the rear bearing  out, which 
will let the mainshaft tilt upward enough so that the gears will  
start coming off.  Did that.  Problem is, the gear at the back  (1st?) 
contacts the case long before the bearing is free.  I removed  the 
circlip which anchors the output shaft to the rear of the bearing,  
and managed to move the bearing a big further out (rearward) by 
moving  it on the shaft as well as the case.  Moving this bearing is 
tedious  and requires prying it on one side then the other, moving it 
mils at a  time.  It still has 1/4 in to go.  But I see no other way 
to get  the gears off the mainshaft.

I just finished off a bottle of Ipswich  Stout, but it didn't help.  
Now what?  There must be a  way.

Jim,
Just did this today (Sat) with a friend who, between the two of us, rebuild  
TR3 and '6 gearboxes for Green Country Triumphs Club members.  This was our  
first foray into a GT6 gearbox which I am doing for my latest purchase.   
Really, the ideal thing to do is to remove the rear bearing first (which we did  
not do) and byusing a bearing separator and a sort of jig (see 
_http://www.vtr.org/maintain/TransRebuild/TRTrans01.pdf_ 
(http://www.vtr.org/maintain/TransRebuild/TRTrans01.pdf)  Page  7 for picture of the jig).  We were still able to 
successfully get the  gearbox apart using the same arrangement.  Let me know if 
I can be of any  other help.
