I have Dr. Evils DVD (bought it forever ago and have yet to watch it) and am hoping to have some fun building up a shorter ratio gear box. I have a huge box of 914 gears and was wondering if I can use the "Ratio Calculator" in the 914/901 gear ratio workbook to pair them back up. For example:
KA 22 : 31 1.41 In this case would a KA be a 22 tooth gear and a 31 tooth gear? I understand that they are typically matched sets and I may get noise or increased wear if they are paired wrong. Thanks. -Aaron |

First you need to sort the gears to see if you can get them back to the original pairs. If they are 901 gears, they will have engraved match numbers. 914 gears don't have match numbers.
All gears should have a Roman Numeral I that shows that it belongs on the mainshaft or a II that shows it belongs on the pinion shaft. Once you have paired them, you can shift the pairs around on the 3rd, 4th and 5th positions. I don't think you will have durability problems with mismatched gears but can have some gear noise. Why don't you try it and let us know the results. |
