[TR] TR 2/3 fan/alternator belts.

[Angelo Graham]

Hello List:
Have an alternator conversion on my TR2 and have struggled with the fan 
belt since installing the alternator. I have used a Gates TR24379 which 
is a 3/4" belt, 38 3/8" long. Impossible tight fit and a bear to try to 
get on or off. The next Gates belt in this series (Truck/bus Green 
Stripe) is 40 5/8" and is too long. Searching the Gates site and found a 
series of 7/8" belts that would seem to do the job at 39 1/8" - which is 
listed by Gates as the "stock" belt for the TR2/3/4 series - TR28386 
(Green Stripe).
Can we use a 7/8" belt on our pulleys? Always thought that the belts 
were supposed to be 3/4" - not worry about it and use it if it fits??
Thanks for any help with this one.
