Massy-Harris disc questions

I believe I have a Massey-Harris 7 foot disc. It has the M-H all over it and I think I can see some remnants of the decal on the draw bar.

My question is, should I try to refurbish the bearings at the end of the "gangs". Or just grease the hell out of them and go for how ever long they last? Are they the wooden bearings?

I am using a couple tubes of grease each time I grease them.

Thanks for any help.

I think there are still some places that make new oil soaked wood bushings if those are worn out. Do an internet search. There are Amish hardware stores that might sell you those.
 
If it were me, I am retired and have a torch,

I would at least remove the two nuts that hold the bearing cap bolts , take the lower cap off lift up on the top disk frame and have a good look
see the condition of the wood bearing,

Make some pictures of them and get a set ordered,

You keep using it, you could finally wear the caps down or weaken the axle ,

However the new cheap disk you buy today have no wooden bearings, only metal to metal and as you are doing I just grease them good, run it
till it squeaks, grease it again, it will last more than my life time,

Nice looking old disk, they do good work, just a bit hard to transport down a hard surface road,

I have made those out of white oak, soaked them in oil to keep them from rotting, drilled a hole in then so gun grease could get thru them. Still working on my old coultipacker after 15 or 20 years.
 
If you have woodworking tools avaible you can make them yourself. But use hard maple that all the factories used because it will soak in the oil that will just stay on the surface of wood like oak. Depending with new bearings how much ware the spools have it might still take 2 tubes of grease at greasings or if no ware anyplace you might be down to a half tube. I got lucky and found a set of new old stalk for the Massey I rebuilt a couple of years back. Mine had the crank for angle adjustment, Got it from scrap yard just a couple of days after they got it in and when rebuilt sold it to Amish. And a drag disk will always do a better job than a 3 point hitch model.
 
I seem to remember looking at wooden bearings before and found they were expensive enough for me to probably try to make them myself.

I have a nice metal lathe that will probably work.

Thanks for the help in how to take it apart to check them.

Can the bearings be replaced by dropping the lower cap and lifting the frame?

Have a 24 plate MH tractor disk that is different than that (bends in middle), but the bearings look the same as well many of the other parts.

Disk has been used for what totals to be several hundred acres since we've got it and it was ancient then. Bearings never been touched.

There is a grease fitting on back. Pump them full of grease and forget about them.
