Trying to remove pilot bearing from 1984 4spd tranny in 84 Fiero. I am origional owner. Have tranny out and clutch off. I can't get the old pilot bearing.

I have rented a slide hammer tool from O'Reilly's. It has a 5 lb slider and an Everr Tough attachment to hook on to the pilot bearing. It has two hardened steel claws that grab on to the back of the pilot bearing. After you slide the claws through the bearing, you screw the threaded back of the tool in to spread the claws.

The problem is, the claws seem to work fairly well. Lots of hard slams with the slider, but no movement of bearing. Now am cutting groves in the bearing. Have used penetrating oil for two days, no help.

any suggestions on how to get it out.

Collapse it with a chisel and pull it out in pieces

An old teacher of mine packed the hole full of grease, used a rod of the same diameter as the pilot shaft, hit it into the crank and the hydraulic force shot the bearing out. it was a neat trick for sure.

There are a number of threads, like: https://www.fiero.nl/forum/A...110502-2-103015.html and https://www.fiero.nl/forum/A...050119-2-055219.html
which indicate that the Fiero does not have a Pilot Bearing.

Pilot bushing is not used on fwd trans in Fiero, leave the old one in or get it out and don't worry about it. Input shaft of trans is not long enough to reach crank shaft, and has no pilot on shaft at all to engage in a bushing.

I guess we're wondering... why?

Ditto "Old school rules" although in my case I am usually the one telling that very same story of how you can quickly and easily remove a pilot bushing.

Detroit iron rules all the rest are just toys.

The clutch kits are a little deceptive as related to the Fiero. Since the plate and disk have a number of applications, the new pilot bearing is included. There's no need to remove the old one, but if you just must, the alignment tool that comes with a clutch kit is actually designed for this purpose. Remove the loop/ball on the end of the tool. Pack the flywheel cavity with heavy grease and insert the end of the alignment tool into the flywheel cavity. Smack the end of the tool with a good rubber mallet or dead blow hammer. In a crunch, I've also used deep well sockets on an extension. Never use a standard socket because it can get inside of some flywheels, requiring you to remove the flywheel. Wooden dowels are discouraged, too because they splinter. Deep well sockets can also be used to align a clutch disk in the absence of an alignment tool.

You can place a few chips of dry ice inside the bearing, repeating several times as it melts, then the slider hammer might work for you.
