Pilot bushing

Is there a pilot bushing for the ZF torque converter? I always thought they just slip in there and are correctly sized to the back of the crank. If there is a bushing, then you definitely do need it -- running without it could cause the torque converter to move with eccentric motion and that would destroy the front seal on the trans, or worse. I'll look at that engine in my shed again but I'm surprised if there is a bushing.

I would make the main goal getting the M90 pilot bearing out first and then measure the crank recess bore diameter. Compare to the pilot stub on the ZF torque converter. Hopefully they are the same and it'll slip right together.

If not, and if there really is a pilot bushing, I'm happy to pull one out of an automatic motor and ship to you. I imagine it wouldn't be expensive to ship internationally, as small as it is.

I just looked at the photo on the other post and yes i can confirm 100% that there is a bushing that i do not have.
