I have never worked on your model. I have a 7753 and did the right rear bearings. On that model you can't use a socket to loosen a nut and thus I had to cut up an old 1 1/4"??? wrench to put a pipe over to get leverage. The book said it was 450 ft/lbs torque.
I needed a 10 ton porta power some threaded rod and a bar to pull it apart and normal shop tools including the 1 1/4? open end wrench. I was lucky to have a sacrificial wrench. I'm sure there is a better puller, but that what I had.
Pro tip, I bought my bearing at Bobcat without thinking first. They were just standard SKF bearings that were 40% cheaper if I just bought them as SKF. So take it apart and get the numbers, then buy the parts.
