Older Maxll tear down

[tattooman]

I have started to tear down my new to me maxll. As I was removing the rims I noticed that the flanges are cast and have no grease zert. The grease fitting is in the middle of the hub. How on earth does the grease get too the bearing like that! Anyway, I got the top off. All wiring is set up on plugs. So it was very easy. As it came apart quick, I had time to remove the 16 hp Briggs. I have an electric hoist in my garage. Makes the job easier! I highly sugest everyone over the age of 50 get one! Anyway, I am sure before it's over I will have a few questions. If anyone can enlighten me about the center grease fitting, I would appreciate it! Thanks in advance. Bryan

Sounds like someone drilled the end of hollow axles to pump grease into inboard bushings. Quite common, probably find the axles full from end to end.

Yes, but that doesn't explain how grease got to the bearings?

If you're stating the 2 outer flanges are stamped with no fitting and the 3rd inner support flange against the outer frame rail has the fitting pressed into the stamping, I'd guess someone put it together wrong and needs a switcheroo.
That section of frame won't rust.

If not and the zerk is in the axle, then as msafi65 explained, it will send grease through the hollow axle to the inner bushing.

The outer flang is cast with no grease zerk! I should have the frame out in the next day or two. There may be a grease zerk on the inside of the tub. It's quite a mess inside the tub. I am going to set the frame on a wheel barrow and fill with hot water and dawn dish soap. Add a toilet brush an I should bee able to cut through years of grime! I am replacing the bearings and flanges anyway. While I have the frame out I will be adding inner bearings as well.
