[Roadsters] belt problem

[Bubba]

V-belt numbers indicate cross-sectional dimension and length.  There are 2 
different numbering systems that make it a bit more challenging.

V-belts are expressed in inches. For US V-belts, the part number first has a 
letter to id the cross section, and a number to id the approx inside length. 
Narrow V-belts are id'd by a number - 3,5, or 8 --- for the belt top width 
in 1/8" increments, followed by the letter "V." The rest of the digits 
indicate the effective belt length in tenths of inches.

The metric belts made to ISO standards have an ISO number showing the width 
about 1/3 down the "V" and the "theoretical" length based on the diameter 
when measured 1/3 down the "V".

For belts made to DIN standards, the numbers indicate top width and inside 
circumference in millimeters.

In other words, if you need a belt longer than the 7340, assuming the same 
manufacturer, you want a highter numbered belt, the number depends on how 
much more length you need.

Hope this confusion helps a bit.
