Pilot bearing/bushing removal

Yeah, the insert for the bearing. . .you need a BIG nut. Weld it on and drive in a bolt to make a screw jack.

those are not exactly supposed to come out.

It's a TJ manual transmission thing I think. There were quite a few changes to the TJ era 4.0's.

didn't have white bread so i used regular flour tortilla, nice and doughy. compacted in there really well, used a 4 lb sledge and a 1/2" drive socket slid in backwards with a 1/2" drive extensions to fill the hole so nothing could squeeze by.

my puller is/was the type that has the slide hammer attachment, probably only 2 bs but the fingers slip over the bevel and slide out. sorta fixed that issue by using a disc on a dremel and flattening that groove so the fingers could actually grab a flat edge. then the 90* edge of the finger broke off. then i got disgusted and quit.

i've put a pilot bearing in one of these before after removing the original automatic from my 1998. the early transmission torque converters must have had a larger centering nub that fit into the crank because when i did that one i only had to install the pilot bearing without removing a pilot sleeve. the bearing i'm installing has an OD of 1.8 as seen in the link below.

Yeah, that style has the sleeve and bearing as one unit. The sleeve is likely too big for the hydro bread trick.

I had to do that once for a custom pilot bushing. I ended up drilling and tapping holes and using a steering wheel puller. I think now that I have a welder, I would weld a nut in the ID and press it out with a bolt.

SUCCESS! found a nut that fit inside the pilot bushing after grinding off the 6 points. at first it slid out as i threaded the bolt in but after tack welding the nut to the sleeve it came out. i don't think the small grooves from the dremel wheel should make a difference in the balance of the crankshaft.

Brilliant!

Brilliant!

Thanks!

weld a nut to it and take a few inches of appropriately sized all thread with a nut welded to the end and crank it down.
