When trying to get a stuck faceplate off the spindle, I put the faceplate wrench on and gave it a sharp whack. Unfortunately, the locking pin apparently was not seated all the way in one of the holes in the pulley/indexing plate. The indexing plate now has about six positions (next to one another) whereby the pin will not seat correctly in the holes. I believe the only remedy is to replace the pulley/indexing plate. Has anyone done this? Can you give me an idea of what's involved to do the replacement. Thanks.

The holes probably have the edges dinged, thus blocking the pin. This can be cleaned up with a reamer at the top of the hole to open them up again. If you have drill bits the exact size you can use them by hand in vice grips to remove the distorted metal being careful to not go very deep so the indexing pin stay tight in it.
Do as Gary suggests, then use a 1/8” or so larger bit by hand to remove the burr that will stick up from the hole and slightly chamfer the edge.
Gary/Doug - thanks for your suggestions. I'll post my results once I've tried it.
Here's the update - I started by trying to identify the "bruised" indexing holes. I couldn't find them by visual inspection so I went through the process of putting the indexing pin in each hole, until I found those that the pin wouldn't seat properly in. During the process I noted that sometimes the spring in the pin apparatus did not move the pin into the hole all the way. Once I made that discovery, I made sure the pin went completely into each hole. Thus, it looks like my pulley/indexing plate is intact. Now, when I move the pin advancement lever to lock the spindle, I make sure the pin is properly seated.
Glad to hear that. The less you have to tinker the better.
Great! Check the pin - a little polishing may help and very slight radius chamfer if it doesnt have one. A little paste wax applied to the pin and each hole, possibly with a q tip, could help. There might be small burrs on some holes.
Good suggestion Doug.

Not sure what the Grizzly lathe indexing pin is like, but on all the lathes I've seen I wouldn't use the indexing mechanism for removing chucks/faceplates, especially if they are stuck....they are too flimsy and not made to handle that. There must be another method for your lathe or come up with your own method.
