Detector 72 #1 Posted October 16, 2016 (edited) This is a simple question I'm sure for the Kohler Mag. I need to remove the PTO pulley "the part that meets the disc or just the outer part" to sand and repaint.... I see a small snap ring and a larger. I'm thinking removing the larger one would allow it to slide off? Thanks Edited October 16, 2016 by Detector Share this post Link to post Share on other sites
doc724 925 #2 Posted October 16, 2016 You did not identify which model tractor. If it is one of the newer ones (1978 and later C series and its descendants) Just slide the bail (the curved thing that attaches to the stub shaft on the PTO) out of the way and removed the PTO brake. With those out of the way, the whole thing just slides right off. The snap ring that you see actually is there to hold the outer ball bearing into the PTO bell 1 Share this post Link to post Share on other sites

Detector 72 #4 Posted October 16, 2016 (edited) Great, with a yank it come off. Do I need to apply any grease the the shaft upon install? I know none needs to get on the friction surface. Thanks again Edited October 16, 2016 by Detector Share this post Link to post Share on other sites
doc724 925 #5 Posted October 17, 2016 Do not put grease on the shaft. If the needle bearing inside the PTO is dry, I usually get some high temp grease and force it between the rollers. The grease seal should keep the grease from escaping. The ball bearing that supports the stub shaft on the PTO bell is likely to be dry as well. Remove the large snap ring and tap out the stub shaft and bearing from the inside (it is a light press fit). Take the small snap ring off and the stub shaft will fall out. Carefully remove one of the seals on this bearing and repack with high temp grease. Reinstall the seal and reinstall the stub shaft and small snap ring. Lube the outside of this bearing with oil and the PTO where the bearing mounts with oil and tap the bearing in from the outside using a socket which matches the outer bearing race diameter. If you have a press, it is easier to keep the bearing square during the install, but with care you can do it with a 16-22 oz hammer. Takes a bit of practice. 3 Share this post Link to post Share on other sites

I've got a new brake ordered, mine is down to the rivets... I read .012" gap engaged Share this post Link to post Share on other sites
