[TR] gearbox

[Allen Hess]

I don't have the manual in front of me but I recall that the bearing  
is driven/pressed onto the main shaft before the shaft with assembled  
gears is put into the case. Years ago I bought a length of iron pipe  
and a cap which proved to be the proper (close enough) diameter to  
slide over the rear of the shaft and drove the bearing on. More  
recently I may have used a bearing puller to press it on--don't  
remember now. If its already in the case, there may be something you  
can't see that is preventing from going on fully. In addition to the  
manual there are some good PDFs on the internet from the Buckeye  
Triumphs and Green County? Colorado? something.
