[Fot] Transmission Question

Yes, I played around with a spare transmission.  The stud can be moved a 
bit, both the reverse idler gear and the reverse gear on the main shaft 
prevent it from coming all the way out.  I'm always hoping for an easy 
way out.

As it turned out, two of my Triumph buddies, John Phillips and Sam 
Clark, came over and helped me out of this dilemma.  It didn't really 
take as long as you would think.  We pulled the transmission and OD.  
Pulled the OD off the back.  Removed the adapter plate. Removed the 
small metal plate that locks the counter shaft and reverse shaft in 
position.  Slid the reverse shaft back until the gear was lose.  Used a 
magnet to work the gear into the lever and align it with the reverse 
shaft.   Slid the shaft back in.  Reattached the locking plate.  Bolted 
the OD back on and stuck it back into the car.

In the OD repair manual at vtr.org, Sam and I suggested mounting the OD 
and transmission when in a vertical position.  This keeps the two 
splines from becoming misaligned.  We used that method today and it 
worked beautifully.  Mounted the OD vertically with the rear flange on a 
piece of wood.  Dropped the transmission into it and tightened it down 
without a hitch.  The worst problem we had was getting the tranny/OD 
back into the car.  That took a couple of hours of jacking around.  But 
eventually, the transmission relented.

This car is the TR250 I've had since it was new.  It served as the get 
away car for my wedding in 1970 and Tom's (my oldest sons) wedding in 
2008.  We are trying to get it restored (or at least semi-restored) for 
my other son (Matt's) wedding in a couple of weeks in Milwaukee. I 
thought this problem had blown us out of the water, but with the help of 
my Triumph friends, I think we still have a good chance of having it there.

Thanks,
Larry Young
