Don't know if this is true or not that's why I ask. I had a guy tell me that in a manual shift SBC 350 truck motor there is a bearing inside of the crank that has to be taken out for a automatic transmission? Any help would be much appreciated, Rob.

Yes, it is a bearing or bushing pressed into the backside of the crank, in the center of the flywheel bolt circle. It is the pilot bearing, and supports the front of the manual transmission input shaft.

So does this have to be taken out? If so, how would I go about taking this out? Do I have to replace it with anything? Thanks for the quick reply sbchevfreak.

yup, it's gotta go for an auto.. auto's don't use anything there

There's no reason to remove it, it's a pressed in bushing, no problem to leave it in place.

If you just want it out, you can get a small hooked puller or chisel one side of it. I've heard of people popping it out with compressed air...I don't see that happening.

You don't have to remove it to install an auto trans. It doesn't interfere. I remove the brass bushings by tapping with a 5/8 tap and turning in a bolt to pull it out.

Ayuh,... The Easiest way I've found to remove a Pilot Bushing/ Bearing is to find a punch or dowel that fits reasonably snug inside the bushing,...
Fill the whole cavity with Grease, Insert the punch/ dowel,+ Wack it with a BFHammer....

It'll push it right Out....

Another way to do it, If it's a Bushing, is to weld a little bead inside it,...
Then let it cool,... It'll shrink it,+ it'll come right out with the tug of your finger...

Ditto, it will not be in the way. If you do wish to take it out anyway, the wooden dowel and grease trick works very well, much better than you might expect. Another trick that works well is a bolt with grooves cut in it, and the end tapered slightly, like a tap. Now I used a dedicated pilot bearing/bushing puller, and one of those might be available for loan at AZ (AutoZone, or as I call 'em, Amateur Zone, ), as well.

Completely OK to leave the bushing/bearing in place. You will sometimes see needle bearing pilot bearings, but most are a sintered 'oilite' or bronze material.

If you decide to remove it anyway, the grease "hydraulic" method works fine (only way I've ever done it, actually), BUT be damn sure that you wear eye protection AND a glove or towel wrapped around the hand that is nearest to the bushing.

Reason being, the grease will be expelled from any crack or crevice that may exist between the bushing ID and the tool used to drive it. This grease will come out under tremendous pressure, enough to penetrate flesh, never mind eyes.

on some fords I have had to pull the stick shift bushing, the Ford torque converter has a protrusion that fits in the hole in the crank. I bought a Vega with V 6 5 speed conversion cheap because the shop that did the high performance rebuild pulled the bushing and the guy that put the engine and trans back together didn't put in a new one The owner had shifting problems. paid for 2 new transmissions before he had enough

Ok guys, thanks for the help again. I'm probably just going to leave it in.

That's what I was wondering. I'm VERY busy with all the stuff I need to do to my car haha. If I ever need to take one out though doubtful, I will remember.
