Don't know how you will remove the bearings. I use the special bearing removal tool from F&P. Don't know if they sell the tool over the counter to anyone who comes in. You can ask but they are quite expensive for a one off job. Would of been cheaper to get someone to do it for you. The shaft goes back in the same way you took it out, after fitting the new bearings.
