Manual Trans Pilot Bushings

This pics donated by Brian_wo. And shows the stock type and the new roller bearing types.

P4876056, designed for Magnum V8 with a manual transmission.

Hey Guy's,
Can someone briefly explain what one is and what it does ?

I am going to put a 4-spd to replace a 727 and if I am not mistaken when you go from automatic to a standard you need to put a pilot bushing in.

THX AGAIN FOR THE INPUT !!!

The pilot bushing goes in the end of the crankshaft and centers the transmission input shaft with the crankshaft. The manual transmission's mainshaft is not completely supported without a proper pilot bushing

better check to see if your crank is bored for a pilot bearing, also if its a 440 is it internal or external balanced. There are many problewms doing this conversion I know i'm in the process, any questions just ask

BUT BUT BUT...the cool Mopar roller bearing pilot that fits in the torque converter centering ring doesn't require machining of the crank, just cut enough off the transmission input shaft to clear.
End of problem.
