Non conventional pilot bearing removal

[black_demon69]

Is there any way you can remove a pilot bearing from a 4.0L without a blind hole puller?

Take regular white bread and force it into the center of the bearing with a tool about the size of the hole keep doing this and pounding it in there. It will eventually force the bearing out. I've used this method several times and it works.

^^That would probably work, but I think grease is quicker if you've got a rod that fits fairly snugly in the bearing. Pack the cavity with grease and hit the rod. It acts like a hydraulic cylinder and pushes the bearing out. The bread wouldn't be quite as messy though.

Yup. What he said.^^^^ bread or grease. I guess bread is less messy. You can whittle a stick down to use as a plunger. It just needs to be something real close to the I’d of the bearing so the bread or grease doesn’t just squirt out around it. You are using the principles of hydraulics to remove the bearing.

Thanks for the input

On a 4.0l it's easy... unbolt the flywheel and knock the pilot bearing out from the other side. The pilot bearing is in the flywheel IIRC.

I've also had to destroy the bearing once, and use a dremel with a milling bit to cut through the outer portion, then use a cold chisel to knock it apart for removal. Worked well, but you have to be very careful not to damage anything with the dremel bit and the chisel. This one was seized in place and no other method worked to remove it. I've since bought a slide-hammer with an internal bearing puller. Harbor freight brand. It works very well.

Bread didn't work neither did grease.. I ended up extracting bearings and cage then splitting outer race and collapsing it. Didn't even do any damage to the crankshaft ?

Wow. That one was really stuck.

Some of them just don't understand physics and you have to break them. Glad you got it out.
