cjb398 25 #1 Posted November 21, 2019 I just picked up a C-160. I bought it with a snowplow attached, so didn't notice that the PTO seems to always be engaged.The outer part of the PTO is always spinning and when I disengage it, it doesn't stay disengaged. It just falls together and there is no spring pressure on the PTO handle like on my 312-8 that keeps the clutch plates apart. The first picture shows the spring between the rod and the triangular plate (not sure what it's called). Is it connected right? It has no tension and actually seems too big. Also, in the second picture in area 1, there is no return spring like on my 312-8 that keeps the PTO handle in the disengaged position. Should there be? Or is there a spring in area 3 in the hub that keeps the clutch plates separated? The IPL's I've seen are fuzzy and I can't make it out. Thanks. Share this post Link to post Share on other sites
Pullstart 67,082 #2 Posted November 21, 2019 If I haven’t said hi yet, ! it looks like that spring is much too large. It also appears you are missing the pro brake components. This C-160 doesn’t have the spring, but it does have the brake at least. Share this post Link to post Share on other sites
cjb398 25 #3 Posted November 22, 2019 Thanks. Actually that spring was kinked when I took the picture. I straightened it out and it fits without a bend in it. However, it has no tension when it is engaged and very little when it is disengaged. So I think it is too big, too. Would the missing brake pieces cause the problems I'm having? Seems like there's still a spring somewhere that should provide tension that is missing or stretched. Just not sure how it is supposed to work. Share this post Link to post Share on other sites
Pullstart 67,082 #4 Posted November 22, 2019 I will have to look around to see what else I have for reference on that style PTO. The spring helps keep it in position (I think engaged and disengaged both alike) and the little brake stops the spinning when it is disengaged. Have you looked through manuals and parts lists for the machine to see what the proper spring is? Possibly if you have trouble finding one you could pull that spring and take it to ACE or another hardware store to match up to a similar spring. My local store has about every spring one might imagine in the GT size range. 1 Share this post Link to post Share on other sites
cjb398 25 #5 Posted November 22, 2019 I just ordered a brake on ebay. I've downloaded the manual and IPL from this forum. I do see a spring in the hub on the IPL, so I'm going to take it apart and see if it's missing or something else is not right. Thanks for your help. 1 Share this post Link to post Share on other sites
608KEB 796 #6 Posted November 23, 2019 Try adjusting your PTO engagement rod. Turn it back to the unpainted part on the threads of the rod. Share this post Link to post Share on other sites
rmaynard 16,373 #7 Posted November 23, 2019 (edited) Just an observation, but you are missing the brake. PTO will never stop spinning without it. Also, the little spring on top is only used to keep tension on the rod to keep it from rattling. Inside the PTO at the end of the crankshaft, there should be a stud (14-106 in drawing) screwed into the end of the crank. Over that stud should be a spring (14-107) that helps push the PTO out when disengaged. This spring pushes the PTO or against the brake pad to stop it. The gap between the pad and the PTO bell when disengaged should be .012". In later models the stud and spring was eliminated and the PTO bell was held outward by the action of a redesigned engage/disengage lever attachment at the end of the PTO bell.

cjb398 25 #8 Posted November 23, 2019 Thanks RMaynard. Spring 14-107 is probably missing. I have the brake parts on order. Share this post Link to post Share on other sites
cjb398 25 #9 Posted November 29, 2019 The brake parts arrived, but when I went to mount the bracket that holds the brake pad, it does not fit. The mounting holes are spaced 3.5" on the bracket and 4" on my tractor. This is a 1974 C-160. I looked at the owner's manual and IPL for that year, and there is no brake pad or mention of a brake. I then looked at the 1975 manual, and it has a paragraph added on how to adjust the brake. So, there is no way to put a brake on a 1974 C-160. Or is there possibly a bracket with 4" spacing?

Razorback 1,133 #10 Posted November 30, 2019 My 1974 C-160 does not have a PTO brake, either. So when the PTO lever is disengaged, the outer can still spin, but there’s not enough friction to turn the belt. 1 Share this post Link to post Share on other sites
Lee1977 7,232 #11 Posted November 30, 2019 (edited) It looks to me that the thorttle cable bracket has it jambed in place. If it mounts there it should be on the back side out of the way PTO triangle. Edited November 30, 2019 by Lee1977 Share this post Link to post Share on other sites

oliver2-44 10,782 #13 Posted November 30, 2019 My 1974 c-160 also does not have a brake. Engine is original to tractor Share this post Link to post Share on other sites
