Are you familiar with the process for replacing and aligning the clutch disc? If so you know you need the alignment tool/pilot shaft to line the clutch up. You can use that tool, provided it's not a plastic one, to remove the old pilot bearing. Simply fill the entire pilot bearing cavity with heavy grease, start your alignment tool in the bushing and drive it with a hammer. The grease will hydraulic the bushing out.
Drive the new one in with the chamfer facing out. Use a good quality grease liberally in the new bushing, enough to fill the cavity behind the bushing then smear it on the running surface.
Before you drive your pilot bearing home, be sure it isn't too large for your crank or the rollers can bind. You can get them a few thousandths under size to solve this problem. If you install one that is too tight for your crank, you will have a chore getting it out, don't ask how I know this!

In case it's not obvious, that only applies if you're replacing the bushing with a roller bearing.

Edit, if you have a bearing in there now the grease method won't work to get it out.
I got this from a post on this forum and worked too easy to believe.
Worked on the bronze pilot bearings.
Might have the bolt size wrong, you will need to check. You need the bolt od to be a little larger than the pilot bushing ID
Get a 3/4" coarse thread bolt, maybe 1-1/2" long, & grind the bolt thread end down to a taper, kinda like the plugs you buy to replace a stripped out oil plug.
Screw your new tool in the soft pilot bushing. When the end of the bolt bottoms out in the crank end, continue turning & the bushing will climb the threads right on out.
good luck and hopes this helps.
Also suggest using a pilot bushing driver to install the new pilot bushing as it is easy to mushroom the pilot bushing id closed and then you will wonder why the 4 speed will not go together.
What type of lube do I use? Do I just coat the inside of the bushing?
I use a good quality regular chassis grease. I pack the entire cavity full of grease making sure it fills the area behind the bushing, if any. I then insert my pilot shaft into the bushing and force the excess out and wipe it off.
The splines on the input shaft should be cleaned and lubed. You don't want globs of grease on it, but you want the surface to not be dry. Kind of like you were cleaning the excess off with wax paper.
The trans frt bearing retainer where the release brg rides needs to be cleaned and lubed as well. Look for circular ridges where the release bearing might hang up. There is a recess inside the inner circumference of the release brg. This needs to be filled with grease. The pivot ball that the release fork sits on needs to be greased as well.
Remember that the retainer spring at the release brg end of the fork goes inside the groove on the brg, not over it.

Not sure what this means??[/QUOTE]
The release bearing sits on the end of the fork, but it slides on the tube that is part of the plate on the front of the trans. The release bearing needs to slide freely on this tube. Over time and because of inadequate lube that tube can show wear in the area the release brg rides. It will show up like rings around the tube, worn into the tube. The release bearing can hang up on those and make your pedal feel funky.
The tube gets cleaned/polished (assuming not worn to the point of needing replacement) and a light film of grease on it. Additionally, if you look inside the inner circle of the release bearing (the part that rides on the tube) you will see a groove . This groove gets filled with grease to flush with the surrounding part of the release brg.
