I'm trying to find a proper key for 6 and 8 speed input shafts. The shafts are 5/8" diameter. I have a key from a mid 70s 8 speed here. Appears to be stepped?? Looks like it should be 5/32 but there's several. How can I narrow it down? @stevasaurus @Racinbob @pfrederi Share this post Link to post Share on other sites
Racinbob 10,256 #27 Posted April 7, 2023 I'm not sure Eric. I was thinking 3/16" on the 5/8" shaft. I'm not sure what you mean by stepped. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,478 #28 Posted April 7, 2023 937221 key is a Woodruff 6 and the size is 5/32" x 5/8". The key is listed as a Hi Pro type in the parts lists and that is what you are describing. The extended ends prevent the key from trying to rotate when installing. I do not know if the #6 is a standard key or one with the extended ends making it a Hi Pro style. 1 1 Share this post Link to post Share on other sites

Racinbob 10,256 #30 Posted April 7, 2023 I looked up the key for my 2005 8 speed. P/N 937108 which is 1/4" x 1 3/8" which likely is correct. I'm comfortable in saying that there isn't any of those stepped keys on the tractor. 1 Share this post Link to post Share on other sites

Is there a specific point or need to be extension other than ease of installation? Share this post Link to post Share on other sites
Racinbob 10,256 #32 Posted April 7, 2023 I have no clue. I've never seen one before. Share this post Link to post Share on other sites
