oliver2-44 11,495 #2 Posted May 28 Check you idler pulley to make sure it has belt tight and the transmission drive pulley, maybe it lost its key. Also check that your axles are tight to the hub and not rotating while the hub stays still. 1 Share this post Link to post Share on other sites
peter lena 9,893 #3 Posted May 28 @Redtickuleez probable opportunity ? idler pulleys are known for lubrication failure and typical undersize bearings , do a complete functionality check for every related belt hand off direction , a lot of my problem elimination is based on REPEDITIVE FAILURE . look over every stage , pete Share this post Link to post Share on other sites

pfrederi 20,609 #6 Posted May 28 (edited) paint a line across the hub and axle on each side then after you try to move make sure they haven't shifted. D series have very hefty axle key but they can shear. Does the engine labor at all when yo try to move??? Edited May 28 by pfrederi 3 Share this post Link to post Share on other sites

pfrederi 20,609 #11 Posted Sunday at 05:46 PM There are no idler pulleys First question Did the 3 pt hitch or mid mount operate while you had it running? If they did work next question Can you push the tractor with tow valve closed...Yes or no? After you answer these 2 questions we can proceed with diagnosis 1 Share this post Link to post Share on other sites

I turned it to push it outta the way but then I tightened it back… im disgusted… about this… im eagerly anticipating your reply Share this post Link to post Share on other sites
pfrederi 20,609 #14 Posted 21 hours ago The loader and backhoe are run off a separate pump. Not relevant to you problem. Can you push the tractor if you close the tow valve. Share this post Link to post Share on other sites

pfrederi 20,609 #16 Posted 4 hours ago (edited) Those are needles from failed needle bearings. You are going to have to completely dissemble the transaxle to find out which bearing failed. Looking at the size it is one of the closed end needle bearing in the case, Edit depending on the year of your D it may be the needle bearing on the end of the differential (at least one year used it instead of the 1533 ball bearing) Do you have the sunstrand manual?"
