Faunsdale, AL | I’m confident most of our fleet of old 20, 30, 40 and 50 series Deeres have never had them checked. Had one axle bearing go out on a 5020 once and had an axle snap off of a 6030 once but that had nothing to do with bearings since it snapped off outside of a good outer bearing.
I guess it’s just the best hope you’ll catch a bearing failure before it gets serious. Pretty low yield diagnostic but doesn’t take a lot of time or effort to do it. Question is are you willing to take off the final if you find one that’s a little high. If you take off the final, are you willing to follow the procedure that is required to adjust it properly? It’s not like adjusting wheel bearings on a grain cart or wagon. You have to measure for and use shims between the end of the axle and the planetary carrier so the retaining bolt can be torqued to spec. If you adjust bearing preload using that bolt and the lock plate on its head, you’re setting it up for failure later. Might work on a small tractor but not a good bet on anything that ever pulls hard. | |
