Shade Tree Data: Woodruff Keys
The intrepid Shade Tree Mechanics have put together a list of all the Woodruff Keys used in the Cub Tractor. The TC-37A Parts Catalog has cross references to the Woodruff Key numbers. But the later Parts Catalogs only refer to the key by the part number and dimensions. But all is not lost. MSC (a supplier to machine shops and other industrial concerns), has a table in their Big Book that has a list of all the Woodruff Keys, their dimensions and a USA Std. No. We think that the USA Std. No. allows manufacturers other than Woodruff to also make Keys. In any event, the list of the Woodruff Keys used in the Cub are shown below in a gif, taken from the spreadsheet. The list is also in text format below the gif.
On the off chance that you lose a key or need an extra, you now know what to ask for.
