?#1: Are you looking to do it on the boat or are you removing your strut?
#2: How old is the bearing?
#3: How thick do you think the broze material is that supports the rubber?
The reason for the #2 & 3 questions; some times it's EZ'r to just take a hack saw and split one side or even opposite sides of the bearing and drive it out with a brass/aluminum punch. If they are real thin and been in there for a long while, they'll never press out but just crumble up then seize up the press arbor.
Extracted properly, one can use a length of fine thread all-thread with several fender
washers and lube it with anti-sieze, which should draw it right in. Providing it's not too big (over 1- 1/4").
If it's out of the boat and in good shape (the bronze) take it to a shop that can press it out.
If it's attached to the boat, it'll take a porta-power, all-thread and the proper arbor to fit the bearing. Porta-Powers are not cheap
, even to rent!
You may be better off paying a yard to do it. You have to know what your doing or you can ruin the strut and trying to find the proper replacement could be costly.
If the yard ruins it, they buy it.
