[Healeys] BJ7 gearbox assembly problems?

[Warthodson at aol.com]

Do not try to grind the laygear. You will destroy it.
You need to determine why it won't fit. Is it really too long? 
If you still have your old laygear, compare the length of it to your  
rebuilt gear.
If not, it is relatively easy to measure the distance between the two  
bearing surfaces & compare this to the  total length of the laygear  plus thrust 
washers & thrust plates.
You may need thinner thrust washers, but I would not jump to this  
conclusion.
 
It is possible that your problem is simply assembling the laygear, two  
thrust washers & two thrust plates. They can be a bit difficult to get them  
all aligned.  
 
Finally,you need to have the correct end float when it is all assembled.  
See the service manual for this information. 
 
If the rebuilt gear is indeed too long, then I would personally expect the  
supplier to replace it with a correct one, regardless of how much time has  
elapsed since it has not been used & was "dead on arrival".

Fellow  Healeyoids,

I'm having a difficult time assembling My 63 BJ7  centershift gearbox.  I
can't seem to get the laygear in with the  thrust washers.  The thrust
washers are too thick!  I have a  rebuilt #3649 laygear, courtesy of AH
Spares.  It has a new first gear  nicely welded to it.  It has been
refurbished and appears to be  hardened and really nice.  However, it appear
to be too long and there  is no room for the thrust washers to fit.  It 
looks
like the thrust  end of the laygear (nearer the first gear) is too long.
Could I grind this  down to the appropriate length?  That would be very 
tough
to do  equally around the diameter of the laygear.   Or,  should I  look 
for a
new laygear?  I bought this like six years ago, so I doubt  that I could
exchange it.  Also, I am using the original BJ7 gearbox  case.  Please
advise!  Thanks!
