I went through at least one a year for a few years. Bought an aftermarket one from someplace that was quite a bit beefier. It needed a little modifications of the shaft and bolt pattern to work, but it was good for the year before the combine burned down. Took the motor out before it left though.


What about some webbed straps for the links rather than the metal flat iron. something like travel limit straps on off road racing trucks.https://www.amazon.ca/Explorer-Pro-C...25404467&psc=1

Not sure those straps are the right product for this requirement ....... don’t know!

CihMech is pretty sure the software is continually trying to hold the concave at its “set position” so I’m thinking it has to have cushioning for up & down movement to be effective.

Think I would put a switch on it, shut it off when not in use.

That still won't be good enough when a wad goes in there. Remember there is 600HP in these combines now, something has to give!

That little thing made in China is not what it thinks it is.
That thing is terrible by design and will never have the strength of the old screw on the 1400 series.
They did it backwards, the worm gear should be the driven, not the drive

Pretty sure if you turn ACS off then the concave motor shouldn’t be trying to correct itself.

Actually they’re made in Spain.

You could have a very good point there.

You would think problem would be solved for all ‘50 series machines running full “harvest command”?

If not ...... there’s going to be plenty of pissed off customers with new machines.

I think this is probably right. The CR 900 series returns everything back to whatever the saved crop settings are when the resume button or whatever it is is pressed. I'm sure case has a similar deal.

You mean like a hydraulic cylinder positioned and accumulator protected mount?
Saw something like that somewhere, can go from 50 to 7mm in 2 seconds too!
