Found old disc set. Need ideas for worn out wooden bushings.

[SDBOB]

I found a used smaller gang disc. I guess that is what there called for my Cub Cadets. The axle shaft has wooden bushings. The bushings are split. What kind of wood be good to replace these worn out ones? Or use other material?

Back in the day the wood bushings were split to allow for the removal/re assy without taking the gang apart.
I've made them out of ash/oak or whatever we had on the farm.

I agree, some hard wood.

Sounds like an Allis Chalmers GT disc if it is a GT size unit.]
You might try nosing around simpletractors.com as Simplicity took over the A/C line I believe and that site includes the AC GT's as well

We had to make wooden blocks for a certain job. We used maple as specified on the print.

Split halves as you described, then drilled and end milled* to size.

* this was done on a CNC milling machine using circular interpolation. A hole saw for be fine for a disk

Thank you guys. I knew someone would know. Thought about aluminum, bronze. Then I have wood working tools so wood it is.Years ago my neighbor lent me his disc s worked well so when I saw these at tractor junk yard I couldnt pass them up. Rusty buy usable.

White Oak (closed cell wood) will take more wet/dry cycling than Red Oak or Ash (both open cell woods). Yes a real disk will see temperature and humidity extremes in use. I remember my brother rebuilding an old disk in Farm Shop class. I'm sure he used oil/grease soaked White Oak for that.

I have used hard maple for chain tightener blocks. Usually soak the maple in hot oil initially and then lubing the chain after each use keeps them from drying out. Example; some garden tractor snow throwers with drive chain.

Hmm thanks for the tips. Geez there is still a lot to learn at 72.

My son, who works part time for a manure handling dealer once told me Husky still uses wood bearings in their pumps. Maybe they make one close to what you need with little to no modification ?

I would think Maple is what it had, think that's what most old New Holland balers used for slides on the wadboard or on the plunger. Also think that's what Deere was using for auger bearings in combines into the mid 70's.

So who do you know at a machine shop? For tilling up a garden, wonder would phenolic, UHMW, or Nylon work? There are other pretty tough plastics, but I think these might be the best/most common. Modern plastics helped put wood bearings into the obsolete category--but often time they are way more expensive than metal. Its all about the application of the part.
