nhfootdragger Posted May 17, 2011 Posted May 17, 2011 Well after much reading here over the years about the Landlord differential I had enough info to rebuild one 2 weeks ago. I read here that if one followed the Simplicity technical info to the "t" so to speak it would go well. I have a 3210V that had a differential that sounded like a blender on low speed with ball bearings in it when it was moving regardless of turning or not. I had a 2212 tractor chassis for parts that I used its differential along with the one from the 3210V and between the two I was able to make one good one. In taking the 2 apart I realized someone was into it before and had put in really low grade bolts that go through the gears inside and one had broken causing a mess inside. I replaced the bolts with grade 5 bolts, cleaned everything really good put all the spacers and bushings in their proper locations, greased it really well, and made sure that I put the one large washer/spacer on the axle before installing the outside hub, I torqued the 2 3/8-24 bolts on the outside hub to 25 ft/lbs and it works really well. Because of the fine threads it takes a while to get it to the proper torque and it almost seemed like the bolts were going to break of in the holes even though I chased the threads really well with a bottoming tap first, how ever it worked out well. I am deeply grateful for all the technical info provided by all you great fans of a incredibly well engineered machine. I have 2 landlords 990314 and 990568 I have had both working for me on my property for nearly 17 years now.
