I did this on my 38 Master, which is very similar. I used a pipe and a rubber mallet to drive the sleeve on. It was tricky because of the following problem: If you don't drive it down far enough the axle will not go into the bearing far enough to install the C clip. When the sleeve was driven far enough, the end if the sleeve did not sit under the lip of the old style seal. However a new modern style seal had the lip further towards the outside and it worked perfectly. I looked up the sleeve online at the manufactures website.
