My bearings on that shaft are original at 3000 sep hours, i dont have variable drive though, i wonder if it isnt more the load from the corn head and that big sheave taking it out

My same bearing went out this fall too,dint catch it time and had to put a new shaft on also

I will have to check that bearing on mine this off-season. I thought mine had a grease line on it. How do you keep your combine so clean. Mine is filthy. Great video
