I wasn't planning on this, but the opportunity came up this weekend to look at a PT1070 that was for sale.
I'm interested; because I have the exact same thing, and the last time I needed scrap parts for it, my wife had to call scrap yards in Pennsylvania, Kansas, Michigan...among others. We did find the part at Fry's in Pennsylvania after he searched for a couple of days.
That got me thinking that this seven foot haybine may be somewhat rare, and I should start thinking about the future. Either get another for parts, or start just milking the one I have with as little repair as possible; until I can get something else.
The question at hand is:
When I looked at the one that was for sale, everything seemed to be in working order, except the bottom conditioning roll had a wobble to it.
If I looked at the end near the hydraulic lift ram, I could definitely notice that it behaved like it was off center. I could see the circular outline of the roll move with respect to its mounting point as it went around.
Now, the bearing ran cool, there were no squeals or anything like that.
But, there was a noticeable motion to the whole haybine, where all of it moved up and down in rhythm with the off center nature of the roll; and I could see that the shaft was making the bearing move around as its center changed. (but again...no play, no squeals, no heat)
I've seen rubber rolls get out of shape and make a haybine rock, but their shafts ran true through the end bearings and they ran like that for years. With these steel rolls, I just wonder if this is more of an issue. That steel ain't gonna give. Isn't it just going to keep trying to wallow out that bearing...and won't it succeed after a short while?
Or, has anybody seen these steel conditioning rolls run like this for a long time with no issues?
