what is that thing called in the rear of my crank ?
 

sure, it is some sort of bearing for the input shaft of my muncie. i have an auto motor that i need to mate with a manual trans.....what is the "insert" in the crank called ? my new clutch kit did not come with one and i need to tell the local parts guy what i need......

pilot bearing

Hopefully you have a crank that a pilot bearing will fit in, I had to get a brass pilot bearing and turn it down to fit in the crank of a 1967 400.

thanks guys...it looks as if it will fit fine. i thought about trying to remove my old one and swap it over to the new motor....guess that is a bad idea ? is the bearing different than the "housing" it rides in ? are they two different part numbers ??

Pack grease in the old one, stick a pilot snout in it and hit firmly with a light hammer, it'll hydraulic itself out to be installed in the new motor. Better yet, buy new one, tap it in place and you'll have one in both cranks

I agree with KYflier buy a new one. They aren't that expensive. The do make a bushing and a bearing for this purpose I believe. Either one will work...BB

Keep in mind if you use the bearing instead of the bushing that the bellhousing alignment needs to be closer/tighter. This has an effect on shift quality and trans life. In my experience the bushing works fine, and no real advantage over using the bearing.

am i in trouble ? i need the rusty/silver one to be like the oily/dirty one.....

Sometimes the titles of these threads are absolutely priceless.

;);) ;)

Its called the base

No, your fine, the one on the left just doesn't have a pilot bearing/bushing in it. The one on the right has a pilot bearing in it.

Since the pic on the right shows a bearing instead of a bushing, I wouldn't try to remove it. Just get a new one and install in your "new" crank.
Every time I've tried to remove a pilot bearing it has come apart and was useless.You can remove a bushing with the method KYflier recommended.

Good luck!

thanks guys the new one was $30.00 ! but it looks like a much better unit than the brass "bushing"....fed mogul part #7109
