 
Hi Sheila. I'm no expert on motors and without a diagram I'm kind of at a loss to identify exactly what components interact how. However, there is a web page I found here: In general, gears and belt drives change rotational frequency by the ratio of their circumferences, which is the same as the ratio of their radii. So I expect a ratio of 11.474 / 7.027 (or its inverse) will need to be included. Hope this points you in a fruitful direction.
