Claas lexion reel

Hi. Anyone had problems with reel speed during cutting on a Lexion? Seems to be slowing down then speeding up without any adjustment.

There was a thread about it a month ago.
From my so far limited experience with 400 series, check the reel speed sensor and wiring, then settings in Cebis, then when that still fails, live with it and just correct speed manually.

Thanks David. Checked the reel sensor and wiring but didn't seem to work so will check settings on Cebis.
Jonathan. It's a Lexion 520 but suppose similar to 400 series.

Our MF has a ground speed setting, so reel speed matches, had me confused when I first drove it. Just a thought

Thanks. It's increasing and decreasing speed irrespective of ground speed.

There is a potemtiometer on real pump if you open left panel reel pump is eye level near wheel on back of black pump theres a silver vale block with ram facing in combine on end of ram is a linkage to potentiometer chech that's still there

Also check for play in the arm that moves the sensor, there’s a little brass bush in the end of the valve that moves the arm. The bushes gets worn so the arm can move back and forth by its self.
I replaced mine when doing a winter service.

I had same problem with mine turned out it was electric solenoids on valve bolted to pump
