Another in the ongoing projects for my WD45's. This time I worked on fixing the sloppy snap-coupler system. Sometime in the past I found a very nice bell on e-bay that didn't cost a kings ransom. This shot shows the minimal wear, as opposed to the heavily worn one on the tractor. http://s1378.photobucket.com/user/dlsledge51/media/100_0812_zpsayym0ryx.jpg.html" rel="nofollow">  http://s1378.photobucket.com/user/dlsledge51/media/100_0817_zpsf26ss4de.jpg.html" rel="nofollow">  http://s1378.photobucket.com/user/dlsledge51/media/100_0818_zps7xphyytn.jpg.html" rel="nofollow">  The fork the bell mounts on. http://s1378.photobucket.com/user/dlsledge51/media/100_0856_zpspivobxak.jpg.html" rel="nofollow">  http://s1378.photobucket.com/user/dlsledge51/media/100_0857_zpshlbf4ztw.jpg.html" rel="nofollow">  More on this later, have to get ready for work. |

| Mike for gosh sakes replace that double c spring while you have it apart. It could save your life. Good luck with her. |

| Tom, I didn't have time to get to that part. Got a new spring from AGCO. That was an important part of the job to me. |

Mike, Would you be able to show some pictures of the worn out snap coupler bell for comparison? I'd like to see what to look for if one needs replacing. ------------- 1951 CA, 1952 CA with cultivator, 20 Series 8' disc harrow, 2 bottom pick-up plow, forage blower, 2-row rear mounted drill corn planter, Allcrop grain drill, No. 80T sickle mower, MN No. 130 barge box |

[QUOTE=Cernunnos]Mike, Would you be able to show some pictures of the worn out snap coupler bell for comparison? I'd like to see what to look for if one needs replacing. [/QUOT]The bell itself doesn't show wear in most cases, it is the rails where it contacts the fork. In the first couple of pictures you can see the difference between the one I installed and the one I removed. Also the fork gets a deep grove worn in it, hard to see well in the pics but there was a huge difference in the one I took out and the one I installed. In the future I intend to try welding one up and regrinding to fit. Maybe the side view shows the wear better. http://s1378.photobucket.com/user/dlsledge51/media/100_0815_zps2foqs0vf.jpg.html" rel="nofollow">  Minimal wear on the one installed. I cleaned up the edges with a file before assembling. You can also see the new spring in this shot. Getting that spring in there correctly and then getting the pin through is harder than you would think. http://s1378.photobucket.com/user/dlsledge51/media/100_0814_zpsrune7qp0.jpg.html" rel="nofollow">  |

One of the big problems I ran into doing this is getting things apart. Apparently 60 some years is enough time for pins to completely bond with other parts. Had to remove the whole drawbar support from the tractor and replace it. The one used here did not have the adjustable stop block on it. I think it came off an early WD. So I cut one off another piece and welded it on the one used. Of course I found this out after paint. http://s1378.photobucket.com/user/dlsledge51/media/100_0819_zpswxx13lk1.jpg.html" rel="nofollow">  http://s1378.photobucket.com/user/dlsledge51/media/100_0820_zpsf7skj8t8.jpg.html" rel="nofollow">  Not sure how important this is but wanted to have the option to adjust. The finished assembly ready to install. http://s1378.photobucket.com/user/dlsledge51/media/100_0859_zpsau1ydxe2.jpg.html" rel="nofollow">  |

Back together ready to plow. This really tightened up the system. Now when you step on the drawbar to mount the tractor it only moves about half as much as it used to. It's good piece of mind. http://s1378.photobucket.com/user/dlsledge51/media/100_0860_zpsprcus5dg.jpg.html" rel="nofollow">  |
