Lawnmower blade spindles

[cadet cub]

I am working on my mower decks this winter and I noticed that the spindles on my cub cadet and snapper z-turns were loose. I removed the spindle housing which has a grease fitting which I have been greasing religiously though out the cutting seasons 7 now.
My Rant here is that the people who assemble these parts use sealed bearings but they do not remove the inner seals which means that none of the grease gets to the bearings I popped off the seal and found that the bearings were dry even though the case was packed with grease. I have replaced these spindles but I disassembled the new ones and removed the inner seals with a pick. I also drilled out the relief hole and tapped it to install a spring loaded relief valve thought I would share this with you guys as this is such a great site for info

First off, the people who assemble the equipment aren't the ones who select the components. That's the engineers job. Secondly, bearings with seals on only one side are available. Again, that is the engineers job to make the selection.

With that said, I'd prefer that if there are grease fittings installed, the bearings should be the proper ones.

Now on my Cub, the mower deck uses tapered roller bearings and for sure the proper components are used to keep the bearings lubed.
