mnelson721 0 #1 Posted April 14 Hello wheel Horse community! I recently inherited a C1 75. The tractor was running great until all the sudden my son shifted into forward really hard. And then it does not move forward anymore. The engine runs very strong trying to find where I may have broke something. The belt is tight. The pulley looks good. The fan on the transmission is running, but the rear axles won’t move anymore.. I would add a video, but it won’t let me upload it 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,509 #2 Posted April 14 It's possible you sheared a key in one of the rear wheel hubs. Draw a line with a marker from the center of each axle onto the hub. Try to drive and see if one of the hubs turns on the axle. It takes just one to fail to cause a no-drive condition. It could be the right one because the axle is out past the hub. I don't think it could be the pulley behind the fan because the fan is turning. 1 2 Share this post Link to post Share on other sites
mnelson721 0 #3 Posted April 14 Thank you for the advice!!!! I will look at that now drawing a line on the axle. Maybe a stupid question how do I get the hub off of the axle to see if it’s shared? Share this post Link to post Share on other sites
mnelson721 0 #4 Posted April 14 I tried with the marker on the axle to the wheel hub. Neither of them are turning on both sides. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,509 #6 Posted April 14 Did you remount the wheels on the hubs, set them on the ground and drive it? 1 Share this post Link to post Share on other sites
pfrederi 17,164 #7 Posted April 14 I am more a Sunstrand guy, only have 1 Eaton. If you had this problem on a Sunny I would say a transaxle key sheared. In your case #29 Hope some Eton guy stops by soon... 2 Share this post Link to post Share on other sites

8ntruck 6,399 #9 Posted April 15 is there a key in the pulley too? Share this post Link to post Share on other sites
kpinnc 10,822 #10 Posted April 15 There is also a key in the control lever on the pump itself. With the engine switched off, and the cam assembly removed- if you actuate that lever you can hear the driving side of the pump's inner race moving. It has an audible click to it. If the key shears, nothing will move internally. There also won't be a hard stop in the motion of the lever. Share this post Link to post Share on other sites
pfrederi 17,164 #11 Posted April 15 Does the hydro lift work??? 1 Share this post Link to post Share on other sites
953 nut 51,881 #12 Posted April 15 The lower portion of your drive belt appears to be below the guide, it should be resting on top of the guide to catch the belt slack when the tensioner is up. Could be the belt is in a bind. When the engine is running and you apply tension to the belt does it load the engine down? As @pfrederi suggested, if your hydraulic lift is not working then the pump isn't working. Tell us the symptoms one by one and we will help you through this. 2 Share this post Link to post Share on other sites
