rexman72 210 #1 Posted May 12, 2015 I bought a new pto brake to trytostop the pto from moving when disengaged.After two minutes of running the tractor the pto starts moving.I checked the blolts I bought for 15 cents at the hardware store and they were melted and one had broken.Are there an special bolts I need to get?I am pretty sure these bolts are causing the pto to move even with a new brake.

rmaynard 14,907 #2 Posted May 12, 2015 What is the model number? On manual PTO's, the brake is adjusted with the engine STOPPED. Engage the PTO, loosen the nuts on the brake, slide a .012" feeler gauge between the brake pad and the housing. With even pressure on the both ends of the pad, tighten the nuts. Slide the feeler gauge out. When the PTO lever is disengaged, the housing returns outward and the brake pad stops the housing from turning. Some models have internal springs that help push the housing outward, other just use the pulling effect of the housing rod. Share this post Link to post Share on other sites

First of all i am going to buy some grade 8 bolts instead of the grade 2 that i bought.I will engage the PTO and slide a feeler gauge in between the brake pad and housing.I think most of my issues are with the bolts i have in there.Theres so much friction that one of them snapped when i tried tightening it. My model number is 31-17KE02 Share this post Link to post Share on other sites
rmaynard 14,907 #6 Posted May 12, 2015 When properly adjusted, there should not be that much heat. Standard grade-5, 1/4-20 carriage bolts with flat washer, split lock washers, and nuts should work fine. I would remove the housing and clean both the friction side and the brake side. Be sure the clutch material is not glazed by roughing it up a bit with sandpaper. Be sure the bearing is lubricated but not over-lubricated. You don't want grease coming out on to the clutch disc. Re-install the housing and spin it to be sure it runs freely with no drag or unusual noise. Install the brake pad assembly and move it all the way out. Temporarily snug the bolts. Run the tractor with the PTO engaged and disengaged for a short time, then turn it off. It should not be getting hot. When engaging and disengaging the PTO with the brake pad moved out you should have about about 1/8" or more movement. When the PTO is engaged, you should not be able to turn it without turning the crankshaft. When disengaged it should not be touching the clutch plate at all, and spin freely. Then do your adjustments as stated above. 1 Share this post Link to post Share on other sites
rexman72 210 #7 Posted May 12, 2015 Is leaving the brake pad out to see if everything is running accordlingly after i take the housing off and go through it and make sure it doesnt heat up? Share this post Link to post Share on other sites
rmaynard 14,907 #8 Posted May 12, 2015 You can do that. Share this post Link to post Share on other sites

rmaynard 14,907 #10 Posted May 13, 2015 Sounds like the bearing is seized. Share this post Link to post Share on other sites
rexman72 210 #11 Posted May 13, 2015 you mean inside the housing? Share this post Link to post Share on other sites
rmaynard 14,907 #12 Posted May 13, 2015 Sounds that way. I've never had one seize, but I have had to pry one off with a couple of tire irons. 1 Share this post Link to post Share on other sites
rexman72 210 #13 Posted May 13, 2015 I will have to check that out and see if the bearing is ok but something has changed so you could be right on with that. Share this post Link to post Share on other sites
