Finished filling crib this weekend. Started putting picker away and I noticed the wooden idler blocks are the elevator drive chains are done and I am sure they are nla. What wood do you think I should use to fabricate new ones?

I have plenty of available Osage Orange, commonly know as Hedge, that would work for a LONG time. Any kind of Oak would do, or maybe Ash. Some Ash is much finer grain than others. The finer the grain, the longer it will last IMO.
 A few years back, I had a bearing out of my 6 foot 3 point disc. I was thinking of using hedge, but had a mulberry branch by my deer stand that seemed to be about the right size, so I made the new bearing out of mulberry. Probably not the best wood for a bearing, but it will last as long as I need it to.

Did you soak it in oil before using, or did you install it dry.
I have a project I'm building that I'm considering using pieces of 3" x 4" oak blocks for the bearings on 1 1/4" shaft.

Hedge, oak, other hard wood, cut in shape of a half moon key, soak in oil.

Also wood bearings in the old MM disk, had a pair and that hung in the shop for the pattern.

A rotary hoe I had had wood block halves for bearings

Years ago, the Gleaner wood blocks practically dripped oil on the parts room shelves. Some batches were oilier than others.

Lots of wood bearings still available for red combines. Some for the grain elevators might even work for you, with or without minor mods.

I think they are made out of some sort of hard maple, oil impregnated.

Found a scrap of white oak, got a neighbor to cut it on his band saw and it is soaking in oil as we speak. Never heard it called a hedge tree before. Here in politically correct New York we use to call them monkey ball trees, but I wouldn't say that out loud any more.

Believe it or not but you could also try sycamore. When dry it is tougher than oak.

When I redid an all crop 90 with a corn head I used white oak. A small table band saw and some drill bits and your done! Only thing I didn’t do was soak them in oil. Was in a hurry trying to get the project done. But the chains get oiled heavy anyway.

When we rebuilt an old case ground driven manure spreader wer used white oak had lots of it on the farm. Soaked over night in hot used oil before installing. They held up for 20 years when it was sold they still looked in good shape.

And Sycamore has no real grain,if you try to split a piece its very tough to do, dogwood is also very hard wood.

Find someone's firewood pile and ask for a piece of oak and make your blocks. If you don't have the tools to make them for the cost of shipping I will if if you email a sketch with dimensions.

I agree, Oak or Ash are common enough and should do a good job, I know someone mentioned Osage Orange, that is a really hard wood and used to be used as the pin in post frame buildings.

I remember pulling them out of the parts bins at Dad's dealership.  Some would almost drip oil they were so soaked.  Seems like sometimes they came in bags that would be oil-soaked.

Oil soaked oak seems to run forever.  My dad's F3 has white plastic blocks on it.  Seem to work very good as well.  Did Gleaner change over to the plastic or did someone add these?

I’ve used dogwood for mandrel bearings and worked fine.

 I did not soak it in oil. I made the bore about .030 bigger than the shaft, and cut a groove from the grease zerk, out both ways, to within a half inch of the end of the bearing.
 Put it together and pumped it full of grease.
 I'll never wear it out in 20 years of use. I only use it for a couple gardens and a couple acres of food plots.

My '81 L2 has all plastic block idlers too. I figured someone added them. There's hardly a chain on the R52..... I think just the reverser and the unloader drive.... I know the unloader drive has an idler sprocket.
