That makes it a Power Major with a Fordson Major lift. Your year will be 1960.
You will have to strip the brake drum and hub and also take the lift off to get to the nut that holds the halfshaft in. Once the shaft is out the bearing will have to be removed with a puller or press before you get to the seal.
On the website I gave you there is a free manual on the home page, which will help you see how to do it.
