Jointer bearing stuck inside block
Hi, guys! I'm restoring a rusty old magna jointer, and I've been able to get everything apart for cleaning, except for one of the bearings that I'm going to replace. The bearing on the short end of the shaft is stuck inside the aluminum pillow block. There is no hole in the back of the block. I just looks like a friction fit, but the bearing is in there really tight. Any suggestions how I can get this out without damaging the pillow block? Thanks in advance!

Something similar to a pilot bearing puller. Pulls bearings out of blind bores.

There is trick for blind bearing removal in this video. If you have delicate ears, mute the sound.

Re: Jointer bearing stuck inside block
Thanks for the ideas, guys! Love the Video of the grease method. I sat down with some Bud Light thinking juice and “scienced the f out of this.”
The problem was disassembling three parts- the shaft(steel), the bearing(also steel) and the pillow block (aluminum.) If I could get the pillow block off, I could use a regular gear puller to get the bearing off of the shaft. Aluminum expands more than steel, so I took a heat gun to it. A little persuasion and I got it off, then pulled the bearing. Ain’t science great?
