Post by newhollande » Sun Jun 02, 2013 12:34 pm

My 120-54 nectra's cluch has no progression to it .It is either in or out. It has TRACTOSHIFT gearbox [R 7922] with tripler-reverser with change under load capacity. Also has anyone got a gearbox manual for a nectra ! Thanks

your clutch is either engaged or dis engaged ? , is it more severe in reverse position as in very snappy ?

Yes the cluch is engaged or dis engage, as in how many lunches you need to hook on to anything. It might be slightly more severe in reverse position.
The only way to hook on to anything is to use 3 high and let the transmission slip

your problem sounds like your clutch peddle potentiometer switch in the dash on to the peddle , your tractor is gone into safe mode as it has a safety solenoid when the potentiometer goes faulty, you can get this part reconditioned , check your pressures to ensure your packs are ok also , get a good eletrical engineer to check out the potentiometer , I have got a repair manual with wiring diagrams if your stuck I can help ya

Thanks for that John.
I'll get that checked. Would be helpful to know what take off port to use and what pressure it should be.

No problem , if you take up the floor mat and remove the plate over the gearbox to get access to the valve block , 23 bar should be the pressure - remove the oil pressure switch and get a fitting to suit your pressure gauge ,

Correct me if I'm wrong John (and I probably am!) but am I right in thinking the clutch can be calibrated via metadiag software? Seem to remember someone I know having their abrupt clutch problems solved this way...

well when our model gave the trouble the computer couldnt do anything for us - the peddle potentiometer are very delicate switch - and are usually the problem - its no harm to get it checked to rule it out as most now Class dealers havent a clue bout the tractronic systems

hi john

im having a gear box problem with a 120 54 tx with the electronic for/rev on the steering and has 3 duels on the gear stick there is a red light flashing on the dash the tractor has lost drive and trys to move forward and backwards is the 23bar a standard pressure for the gearbox ? im going to lift the floor in the cab and check the pressure and the connections! with the flashing light on the dash im guessing it could be a electrical fault ??

is the tractor driving or does it seem like it is slipping and going no where ?, did it happen all of a sudden or what ?, message me and I can send you on my contact no. , yes 23 bar pressure is correct

First of all, you should callibrate your clutch packs. It should be possible to do that yourself without the need of a computer but you need a manual how to do it.
With most if not all pre 2004 models it works that way, no need for a computer most of the time.
I just recallibrated the revershift of my Ares 566, very simple procedure and works perfectly again now.
Email a good ex Renault dealer (maybe one from the Netherlands) for a manual.
Try tis guy Gerralt at kraggenburg@dijkstralangeweg.nl
Good luck!

Hi, I'm from Germany and I've a problem with the clutch of my Tracoshift. My Renault is a 155.54 TX.
When the direction switch is in forward or backward the clutch is not disengaging 100% and it's difficult to change the gear.
In neutral it's much easier. I already adjusted the clutch pedal by elongating the rod, but it's still not fine. In addition you are not able to dose the clutch carefully.
After talking with a ex Renault dealer, they told me it has to be calibrated by metadoc software. So a technician came with this laptop and connected it for calibration.
We could see all the functions of the sensors etc. on the laptop, but always when we tried to start calibrating of the clutch the software stopped. Looked like any important feedback from a sensor or switch in the gearbox was missing and calibration could not be started. For our surprise no fault was showing by the red light on the dashboard.
Do you know how I can check if all sensors are OK?

Is there a special condition that has to be fulfilled for calibration?

After the technician left I saw that the 1000min^1 power-take off was activated. Could this be the reason why calibration was not possible?


You wrote that I can do the calibration of my clutch without the software.

Where can I get the manual for this?

Thanks and best regards from Germany

Seb from Germany

Hi Seb welcome along , plug out potentiometer switch in dash behind fuse board round black plug on a black lead- see if it makes any difference - seems to me that you're switch is at fault , is your tractor jerking taking off when forward and reverse? , no calibration is needed in tractonic system, I have full workshop repair manual for the tractonic systems as we work a 103 54tx tractonic ,
With similar problems to yous that we fixed
let us know how you get on
John

Welcome along , whats your problem with your clutch is it jumpy ?, what hours are on it , if your potentiometer is worn it would cause a jerk, have you any fault codes showing
