scotty 252 #1 Posted August 28, 2014 (edited) Pully moves freely left and right tried tightening set screw it just loosens right back up. Edited August 28, 2014 by scotty Share this post Link to post Share on other sites
rmaynard 15,628 #2 Posted August 28, 2014 My guess is that the set-screw tip is worn. Get a new set-screw and while you are at it replace the woodruff key as well Share this post Link to post Share on other sites
scotty 252 #3 Posted August 28, 2014 Can I get them at Napa or are they toro only items? Share this post Link to post Share on other sites
rmaynard 15,628 #4 Posted August 29, 2014 Should be available anywhere good hardware is sold. 2 Share this post Link to post Share on other sites
doc724 925 #5 Posted August 29, 2014 The key word in Maynard's reply is GOOD hardware. You want a cup point, square head, hardened set screw. Big Box stores don't usually carry the best variety. Share this post Link to post Share on other sites
scotty 252 #6 Posted August 29, 2014 turned out the woodruff key was completly worn out put both set screw and key in and is solved. Share this post Link to post Share on other sites
rmaynard 15,628 #7 Posted August 29, 2014 (edited) That set screw should be an Allen head, 5/16-18 x 5/16, and the woodruff key is 3/16 x 3/4. If you have a Fastenal in the area, they should have what you need. Oops, looks like you are one step ahead of me.

kudzu3 323 #8 Posted August 31, 2014 My B 80 has two set screws. I didn't know that and the one on the key kept working loose until I found the other one and tightened it, seems to be fine now. Share this post Link to post Share on other sites
