What would be the easiest way to remove the transmission pilot bearing out of the end of the crankshaft. Looks like it requires some kind of special puller. I finally got everything torn down in an effort to solve this chattering/chaffing sound while coasting in gear, but I haven't really found anything yet. The T/O bearing dosen't seem to be bad, although IMO it dosent seem to be retained on the clutch fork very well. Very loose, sloppy. I intend on changing the clutch fork and T/O bearing just as a precaution. I do want to change the pilot bushing while I'm in the area. The clutch/pressure plate is in real good shape, very little wear, so I'll pass on that and put the money somewhere else. Thanks, George:

You know I don't know the correct procedure for getting the bearing out, but this is what I did.

Found a punch that just fit into the center hole.

Pack the bearing with heavy grease.

Hit the punch with a hammer.

Punch compressed grease... and bearing popped right out.

Helpful hint... wrap end of crankshaft with a rag so grease won't splatter.

Method #2:

Run a 5/8"-18 tpi tap in and when it bottoms out keep turning and it will jack the bushing out.

I Agree, absolutely the best way. It'll be out in 60 seconds, it's so easy my mother could do it.

If you don't have a tap that size, just screw an old lag bolt in the bushing and use the bolt as a handle to work the bushing out of the crank.

That grease can get awful messy.

Use modeling clay in place of the grease.

I've used soap shavings with good success, less messy than the grease.

Thanks for the replies and the great ideas. I'll try the tap since I happen to have one handy. Thanks again, great forum to be on.

If you plan on doing this job a few more times it may be a good investment to get a pilot bearing puller such as OTC's 7318 . Proper tool for the proper job.

I bought the OTC puller and it didn't do jack s... 5/8 threaded bolt ground a tinch to fit, play dough, and few whacks with the hammer is all it takes.

I've been using the OTC puller for years and not just on chevys , never had a problem. To each his own, do what works for you.

Somebody should write this up for the tech tips section as it comes up quite often. I tried all the hydraulic methods and a puller with no luck. Didn't want to use a tap as I feared a broken tap would be worse. I cut a slice with a hacksaw blade.

Actually a tap works extremely well, since you are cutting into a very soft metal (bronze or bronze/iron depending on which composition the bushing is made from). Have cut the threads with a tap, and then used a bolt to force it out. Works every time very quickly.

Have never tried the clay, but see it working only on a bushing that is not worn much (and certainly not one with an ovaled bore, since the "piston" needs a straight round bore for it to work against).

+1 on the 5/8's tap trick. Works great.

That is now politically incorrect!

Just wanted to let you guys know, the 5/8" tap worked just great. Probably took me under 3 minutes, and it was in there fairly snug. Thanks again.
