Renault 551 front axel

Hello. I can not take off the front axle, i can not remove the roller. I removed the safety pin, removed the plug at the front of the tractor, and I do not know how to take out the roller. after removing the front cover you can see the shaft and the hole which is threaded. I do not know what this thread is for. I attach some photos.
The tractor is a Renault 551 serial number 5131568
greetings

Bonsoir,

Certainement l’axe est grippé dans le moyeu de corps d’essieu avant.
Il faudra placer un extracteur à inertie dans le trou fileté et tenter l’extraction de l’axe de palonnage.
Si impossible d’extraire cet axe avec l’extracteur à inertie alors il faudra chauffer le moyeu qui reçoit cet axe sur le corps d’essieu.

Good evening,

Probably the axis is seized up in the hub of body of front axle. It will be necessary to place an extractor at inertia in the threaded hole and to try the extraction of the axis of palonnage. If impossible to then extract this axis with the extractor with inertia it will be necessary to heat the hub which receives this axis on the body of axle.
Best regards
