tracto control shaft on Super 5D

Bonjour.
Je dois changer l'arbre de commande de tracto sur mon super 5D raison de cannelures endommagées sur les deux extrémités de l'arbre. Le propriétaire précédent avait soudé les bras à l'arbre et ils sont tous les deux des fuites d'huile. Par broyage de la soudure, j'ai enlevé le bras et le manchon contenant la bague d'étanchéité sur un côté. Si je fais la même chose de l'autre côté, je peux glisser sur l'arbre et un remplacement un retour en?
Tout conseil serait le bienvenu. Merci, John



Bonjour.
I have to change the tracto control shaft on my super 5D due to damaged splines on both ends of the shaft. The previous owner had welded the arms to the shaft and they are both leaking oil. By grinding off the weld, I have removed the arm and sleeve containing the oil seal on one side. If I do the same the other side, can I slide the shaft out and a replacement one back in?
Any advice would be very welcome. Thank you, John

Good evening,

And welcome on the site of "Amicale du Tracteur Renault" (ATR).
In series the tractors Super 5 D were equipped with the assembly of the detection shaft with a screw and retaining nut by pinching of the crank pin of detection on the tree and a sealing by O rings . In after-sales much with these tractors were equipped with the second assembly with a pin and a retaining nut by pinching of the crank pin of detection on the shaft, the sealing was ensured by a lip seal. It would thus be necessary to know with certainty which assembly exists on your tractor to answer you with precision.
Note: on the first assembly the crank pin and the detection shaft are grooved on all the circumference; on the second assembly the same parts are grooved on only one sector of the circumference.
Best regards.

Thank you for your quick response. The end of the shaft is so badly damaged that I cannot tell which type it is for sure but I think it had a spline all the way round the shaft. My concern is whether I can remove this shaft by sliding it out and fitting a replacement without having to remove the heavy top casting under the seat. My mechanical knowledge is limited and I don't want to get into something I cannot finish.
Thank you John

Merci pour votre réponse rapide. L'extrémité de l'arbre est tellement endommagé que je ne peux pas dire quel type il est certain, mais je crois qu'il y avait une spline tout le chemin autour de l'arbre. Ma préoccupation est de savoir si je peux enlever cet arbre en le faisant coulisser et montage d'un remplacement sans avoir à retirer la coulée trop lourde sous le siège. Ma connaissance mécanique est limité et je ne veux pas entrer dans quelque chose que je ne peux pas terminer.
Merci John

Good afternoon,

Thus the whole of part would be first assembly with O ring of sealing.
The detection shaft can be extracted from the right-hand side towards the left without demounting of the block raising by pushing it with a tube with a diameter 40 mm and one 400 mm mini length to guide the lever interns detection at the time of the reassembly of the shaft. During the reinstallation of the shaft it will have to be made sure that the axis of crank pin of detection is well in alignment with the axis of rigidification under the fixing of the sails.
Best regards
