How to tell % of track wear?

How do you tell what percentage of wear that the track parts have on them? Is there some way to measure how much use is left in the undercarrige? I have heard that the sprockets get pointed tips when they are worn alot. Also I have heard that the pins get a flat spot and that the rollers get a sharp edge on the outside when well worn. What are some ways to look at these to know when they will need work.

Keith what machine do you have?? From early to mid 40's & up odds are I have specs. What I would have doesn't show what you are talking about, it just give measurements. It's the bushing that can get a flat spot you can see & not the pin. Flanges can get sharp from poor alignment & not day to day wear off the roller surface. Sprockets can get sharp from packed mud, snow or whatever.

I was looking at an IH TD 6. I want to make sure I am not going to have to replace the under carrige soon because it will be used very litte. I looked at the rear sprocket and it was not worn to a point. It only has one roller on the top and it didn't seem to have a groove in it. The pins in the chain don't show flat spots on them at all. What else can you look at to see where. Where are the cushings that you are talking about? I couldn't see much on the bottom rolers. It doesn't run right now so I could not drive it to see if the tracks made any noise or were loose. Any information you can provide would be great. The machine looks to be pretty straight except that it isn't running. That may be a job in itself to get it going.

Today's Featured Article - Good As New - by Bill Goodwin. In the summer of 1995, my father, Russ Goodwin, and I acquired the 1945 Farmall B that my grandfather used as an overseer on a farm in Waynesboro, Georgia. After my grandfather’s death in 1955, J.P. Rollins, son of the landowner, used the tractor. In the winter 1985, while in his possession the engine block cracked and was unrepairable. He had told my father ... [Read Article]
