| SunTour Two Notch Multiple Freewheel Tool. Made by SunTour, Park Tool, and many others. This tool is needed to remove multiple cog freewheels from hubs. To use, removed the quick-release skewer, slip tool into the matching splines of the freewheel. Clamping the quick release down prevents from destroying the tool and the freewheel during use which is common with this style freewheel remover. You can put the quick release back into place to help keep the tool in place. From there, its all about getting enough torque to break the threads free. One solution is to clamp the tool into a vice attached to a work bench and use the diameter of the wheel to provide leverage. Just make sure you are turning it the right direction! |

SunTour derailleurs have a two-letter date code. On rear derailleurs the code is stamped on the back side of the inner parallel arm. On front derailleurs it is stamped on the back side of the inner cage.
The first letter represents the year. Larry Osborn and I believe O (Oh) is 1972, V is 1979 and A is 1984. As with Shimano, the second letter is the month code, where A is January and L is December.

The earliest Suntour derailleur I have found with a code is marked OF. A rear derailleur marked OD (corresponding to April of 72) was reported by Leighton Walter. I have a bike that dates from between 1970 to 1972 that has the original SunTour derailleurs. These derailleurs do not have date codes on them, so I believe the coding started sometime between 1970 and April of 1972.
