I bought an old Mott flail mower, I need to replace the bearings on the mower spindle and roller.
I've got the roller off and what's left of the bearings are out, only the races are left, and I had to split the outer races to get them out of the roller. There's a grease fitting on each end of the roller axle, but the port in the axle dumps out under the inner bearing race. I doesn't look like there's a way for the grease to make it into the balls. Maybe the bearings have already been replaced with something not oem spec. Unless there's a hole in the inner race that's packed with old ground up bearing balls.
The main spindle bearings may have been done too. On the end opposite the pulleys the bearing cup splits in half after removing 3 bolts. I can see the bearing on the end of the spindle. Thing is, it has the rubber seal on that side, which is the side the grease would have to enter the bearing. The rubber seal would keep the grease out, guess that's why the bearing is shot.
On the pulley end I can't see anything yet. I need a big gear puller to get the pulley off, then I'll have access to that bearing.
I did cut a couple acres with it before all that though. If it cuts that good with shot bearings, I'm looking forward to using it with good bearings. Just had to find the sweet spot on the rpm's to keep it running as smooth as I could.
I'll shoot Alamo an e-mail too, see what happens.
