I'm 99% done with the teardown of my 2001 4.0, and picked up a Lisle 18000 cam bearing installation/removal tool to do the cam bearings. Starting with the rearmost bearing, I'm already running into issues.
I have the appropriately sized expanding driver, and tightened it in the bearing... only to have it shave the bearing a bit without actually budging it even slightly.
To make sure I understand correctly: the expanding driver needs to expand into the bearing itself, right? The only other thing I can imagine would be expanding it into the race, but that would risk galling said race so that doesn't make much sense to me.
Given that this is a 240k engine, am I just looking at a seized bearing? I'm about to step out for a bit, so I was going to hit it with a MAPP torch and quench it with PB Blaster and revisit the whole mess in a couple hours.
Any personal experiences/anecdotes/tips are welcome. Thanks in advance.
