[TR] TR2/3 alternator conversion & belt length.

[Frank Fisher]

Angelo
i did the same thing and machined my old pulley.
before installing the
alternator i tucked the belt on, and then preceded to bold 
up the alternator
to the brackets.
i would warn you that just using one bolt through the front
bracket of the 
alternator will probably lead to problems. you really do need
to fabricate a 
rear bracket. what happens is when you tension the belt you
pull/twist the 
alternator out of alignment.
good luck
frank

TR2/3 alternator conversion & belt length.

Hello Listers:
Just finishing up
an alternator conversion - used a generic AC Delco 7127. I 
used my old
generator pulley with a bit of machining on the AC Delco. Tried to 
fit a new
belt and far too short. Pulled the alternator as close to the block as
possible and still many inches short.
Not sure if this is a "standard"
problem, as the larger o/d of the alternator 
requires a longer belt?
I had a
new Gates segmented belt (groves cut across the belt width). Just 
wondering
how common 3/4" belts are in various lengths? Anyone have a similar 
issue
using the stock pulley and an AC Delco? Any idea of the belt length 
required?
Thanks for any help with this.
Angelo Graham
