troutbum70 858 #1 Posted July 27, 2019 Any one have an idea what component I am missing out of the pto to allow it to track so far out from disk when tractor is running? I am thinking a bushing maybe that is missing. Also pto will not engage with disk, tried adjusting still no lock up. I do not mow with this tractor so not a big deal, but would like it to be useful if needed. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,528 #2 Posted July 27, 2019 Only thing I can think of is the snap ring on the stub shaft that pushes the hub in has slipped out of it's groove allowing the stub shaft to be pushed into the outer bearing. Can you post a picture of the end of the pto pulley? Garry 1 Share this post Link to post Share on other sites
daveoman1966 3,841 #3 Posted July 27, 2019 we need better pics of the entire PTO engagement set up. Just shjowing the gap isn't enough to go on. Show the outer end of the PTO bell and the control rods at the top of the PTO rod linkage. Share this post Link to post Share on other sites

Pullstart 67,092 #5 Posted July 28, 2019 With that style pto, you should be able to run the 3/8” nuts on the end of the pto rod in towards the engine to suck up the gap. If it seems to bind when you adjust it, I’d recommend pulling it apart to look for any pieces of needle bearing or the like that is limiting movement.

gwest_ca-(File Mod) 11,528 #6 Posted July 28, 2019 Not what I expected to see. It looks like the inner bearing race has the word NICE stamped into it. The stub shaft diameter under the bearing is larger than the diameter outside the bearing. Wonder is the stub shaft was driven back out of the bearing if there is a snap ring groove in there. A snap ring would prevent the stub shaft from being forced into the bearing so far. Maybe I'm not seeing the bearing correctly and the NICE is stamped on the shield/seal. If that is the case what looks like a larger diameter on the shaft is the bearing inner race and all is good there. The parts illustrations show the stub shaft larger than the bearing ID and the bearing would butt up against the shoulder and go no farther. If you look at the pto manual the engine pulleys are mounted a specified distance from the engine face. Perhaps that is not correct. Section is named "Engine pulleys".

daveoman1966 3,841 #7 Posted July 28, 2019 (edited) Concur with G-West.... You are missing the OUTER snap ring. Edited July 28, 2019 by daveoman1966 Share this post Link to post Share on other sites
troutbum70 858 #8 Posted July 28, 2019 Thank you Gary for the link to the parts list and instructions. I have had the pto apart and it is missing the seal shown and also I believe it is missing the smaller snap ring. And I have wondered what the proper spacing for the friction disk should be from engine block, this shows 1/4 inch mine being a standard trans. I did try to search this information you have provided, but I am dummer than a box of rocks when trying to search. As I stated my commando is not designated mower, but would like it operable if the need arises. Thank you again for your help and I printed this information for future needs. And yes Daveoman I see the second snap ring it is missing also missing the seal. Share this post Link to post Share on other sites
troutbum70 858 #9 Posted July 28, 2019 Also I will need find out if the seal is available threw one of the vendors that may be a problem on an older pto I suppose. Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,528 #11 Posted July 28, 2019 The 6663 seal is available from SKF or Napa Snap rings are stamped. One side has rounded edges and the other side have sharper edges. The snap ring behind the bearing on the inside should have the sharper edges facing the engine. If you have a snap ring on the outside of the bearing that ring should have the sharper edges facing out. That sharp edge will withstand the load better in the groove.

Garry The snap can get worn and lose tention to hole them in place. It's best to just replace them with new ones when the start giving trouble. Share this post Link to post Share on other sites
troutbum70 858 #13 Posted July 28, 2019 Gary I never knew that about snap rings. Does that apply to all snap rings either inside or outside. Thank you for the numbers Share this post Link to post Share on other sites

Thank you for the numbers It does apply to the internal and external style of ring with the small holes for the pliers to grab. It also applies to the E-type of external snap ring that is pushed on which are also stamped or die-cut. Garry Share this post Link to post Share on other sites
