Iseki tu170 rear axle removal for oil leak fix

[Aussie Tyson]

Gday from Australia, I need to remove the rear axle on my Iseki tu170 landhope tractor to change the leaking axle oil seal. Has anyone done this before or have a service manual. There really is no information on how to do this .I am going to make a youtube clip about it while l am in the process. I think l have to remove the whole side cover to access a circlip that holds the axle in place to slide it out or can it be done from behind the rear cover that the pto shaft protrudes from? Its only a small weep but l think its best to fix it now. Thanks Tyson
