Combining beans today and concave indicator went from 2 to 64 and stayed there - pressing concave adjustment button wouldn't change it. I've had the little linkage that goes from the concave cam to the potentiometer break before and thought that was the problem but it was not - the concave dropped all the way open. It was about dark so couldn't tell for sure what was wrong but reaching back and grabbing the actuator I could move the ram part up and down 3/8" or so. I'm guessing the actuator is toast and the screw broke or something internally went kaput.
I have taken this actuator apart before and will do so again to see if I can fix it. I'm 99% sure dealer will not have one and JD parts shows to replace the actuator a new style is required AH170291 and in addition a new left cam and another part to make the conversion. Close to a thousand bucks in all (that is why I took the old one apart a few years ago and fixed it instead of doing the update - maybe I should have done the update
).
Anyway, to get back in the field so I don't have to wait for parts I will first try to disassemble and fix the old actuator. Second alternative is to lift concave to "2" setting where we use most for beans and weld, pin, make a strap to replace or something that will get me back in the field by noon.
Are there any alternatives to JD parts? Seems like a lot of money for something that looks like it should go on a tv dish antenna.
Any other suggestions as a temporary fix/replacement to get me back in the filed till a rainy day and permanent fix? I think I can measure the proper length with the concave raised to proper position and make a strap with pin holes to replace it. A turnbuckle would be nice.
Any other updates/upgrades to this area of the machine I should be aware of?
Thanks,
John
