Help with a disc harrow

JMHO, the design of this type assembly was not changed very much for 75 years or more only the size of the various components so you're not going to make anything worse if you pump it full of grease. Early designs used a hardwood block as a wear surface for the axle which was later changed to a cast type material that was designed to be replaced when wear was excessive. The basic flaw in the design was there was no way to keep the dirt out of the assembly so the grease mixed with the soil and when it wore out it was just replaced. That's my conclusion after having disassembled the several that I have and repairing/replacing parts, etc. It helps if you have a torch, some big wrenches + a cheater pipe and a BFH with plenty of muscles.

EDIT: Agree with Jim Becker's post, he just has a more delicate way of expressing it!!!!
:D
 
Thanks for everyone’s help. I’ll keep pumping it with grease because I guarantee my father in law has never greased in ever. I’ll pump it with another 40 pumps of grease and run it and pump it again when I’m done. As long as it moves well I’ll probably not replace any discs for now. When I replace the discs will be accessing the bearings as well?
 
Here’s your old and homemade new bearing. They still use wooden bearings in some new equipment today.
Grease grease grease…

Yes, you have to remove the axle to replace the discs.. Bearings will be exposed then if you choose to do so. Stan
 
I will add that looking forward at future repairs, my experience has been that most of this equipment repair parts is NLA (obsolete) so if you intend to make some replacement/repairs it's never too early to try to source the needed parts. It might take a while to find what you need. JMHO Stan
 
There is a place out east that will bespoke manufacture bearings for these old disks…they quoted me $480 for a set of 4. I made my first pair for about $50. We’ll see how long they last..
