Bad Pilot Bushing Symptoms?

AJ/FormS said
No
You get a ball-bearing assembly that fits on the input gear where the bushing would normally go; and the OD fits in the recess on the crank where the Convertor hub would normally go.
If your regular pilot-bushing is damaged, I would either pull it out or ream it. but
if not, I left mine in there 25 years ago, and it hasn't made any trouble.

Ok wait, if you're talking "auto-crank " bushing, then No.
But if "auto-crank" ball-bearing, then yes, lol, as above.

Hey AJ,

I believe we are talking about the same thing. I call it the "auto crank" bearing, since it's what you have to use when you have the automatic crank without the machining for the bushing. Shown below.

I don't have anything against this bearing, but I usually defer to OEM methods. My crank is drilled / reamed for the pilot bushing, but I never reamed the bushing itself after install. I looked up the ID of the pilot bushing and its 0.754". I don't know how much of an interference fit is between the crank and the bushing. I don't work with interference fits often enough to know how much the OD interference will affect the ID, but I could always ream for 0.750" + a couple of thou.
