Yes it has to be pressed/driven out from the bottom, they're a pretty tigh=
t fit.Also over the years I've run into several replacement bushes with the=
ID & OD bore axis slightly off, enough to cause misalignment on the oil pu=
mp drive end with the pump fitted up, so that's another point to pay close =
attention to when replacing them...Glen

I'm pretty sure you have to remove the bushing from the bottom, but there m=
ay be a chance to remove from the topside with an inside bearing puller/sli=
de hammer.=C2=A0 Do not drop the little woodruff key into the engine.

Hi - if the bushing is worn, it needs to be replaced. I would not run the =
gear with a thin shim under it, the shim will not last. I just looked at Mo=
ss and they have that distributor bushing listed for $75 plus or minus.
If you have slop with that distributor drive, you will never get the igniti=
on timing to be rock solid.
